MICHAEL CONTE: All right. Well, we'll begin. Welcome, everybody. Today we're talking about structural design and fabrication workflow for 3D reinforcement. So just before we begin, simple enough, just locate your emergency exit directly in the back, if you'd be so kind as to put your phones on silent or on vibrate. And we'll have a one-hour session, and I hope you guys enjoy.
So what are we talking-- [MICROPHONE SQUEAL] Am I in the wrong zone? I'll stay here. What are we talking about today? We're going to look at our learning objectives. Some of us may have registered way back when and forgot what we were looking at. So we're going to start with our learning objectives.
We're going to talk about who we are as your speakers and who we are as a company. We're going to talk about the "i" in BIM. We're going to look at a traditional workflow, the challenges that correspond to this workflow. And then we're going to look how we could optimize and fix this workflow for something a little more streamline, using the great tech-reinforced concrete BIM designers. And we're going to look at it at four different levels, at four different steps throughout the process. And we'll end with a summary and a question period. So here we go.
Our learning objectives for today is to learn the value of connecting our engineering model to a Revit model, creating a streamlined workflow. We're going to look at the benefits of transferring the intelligent constructability-- what does that mean, taking in our analysis results, and using them for something a little better, doing a design in Revit. We're going to look at connecting our advanced BIM workflow to utilize data that's created with the BIM designers. So we're going to create schedules and drawings. And then we're going to look at exploring Design-to-Fabrication workflow powered by BIM 360.
So my name's Michael Conte. I'm the local product manager for Graitec. In my co-captain seat over here, I have Joseph, who is the product director at Graitec in our headquarters in France. This is all our bio. I won't get into it. It's in the class handouts. You can find it on the web also.
So who we are as Graitec? We are an innovative CAD and BIM software author. We develop cutting edge technology for BIM implementation, and we support softwares for the AEC industry. We are one of the largest Autodesk resellers in the world. And you could see that we have 29 offices, some throughout-- oop, sorry. We have an office in Canada, US, and throughout Europe, with 400 staff. We have 30 plus years in the software analysis solutions and BIM solutions. We have over 50,000 customers worldwide, and we have an extensive BIM technology portfolio tech-tailored to customer service success.
So we'll start off light. What is BIM? We've been talking about BIM for a long time. More and more, it's becoming more relevant. It stands for Building Information Model. We have a nice definition here, but this is a global definition. It represents having a singular model from your feasibility study all the way to your management of your structure of your building.
What we're going to be focusing on today, in terms of a definition, we're going to be talking-- when we say BIM, we're going to see everything that's pre-construction, everything up until fabrication, including fabrication itself. When we talk about BIM here, that's what we'll be focusing on. And so we're creating a singular model to use from the engineering all the way till the detailing or creating the NC files. But we're talking about not just a 3D model, but we're talking about a work process. There's a methodology that's associated to this.
So we're sending things that are simple, like geometry. We're going to be sending things that are a bit more complicated, like intelligence, cross-sectional areas. But we're going to be focusing really on information. And that's where the real power lies, is sending the information, the "i" in BIM, essentially.
So we're going to look at a little traditional workflow of what's happening presently. Some of us may be a bit more accelerated in this. So you have your engineer. He's working many softwares. He's using software for maybe static analysis, for dynamic analysis, for concrete design, for everything that's different. Maybe he's using softwares to draw the structure. But this is very rare, but becoming more and more relevant.
They may be using Revit, but it's not in the same way that the designer or drafters are using Revit. It's in a bit of a different process. Or chances are, if they're creating their drawings, they may be using something as rudimentary as AutoCAD, sometimes maybe even hand sketches. And so these little pluses signify little add-ons to. Maybe they're using add-ons to help them process things a little quicker. These could be in-house add-ons that they've developed within the company. These could be commercially available add-ons.
But also, what they're using most of the time is, us as engineers, we'll use hand [? calcs ?] to validate our design, Excel to speed things up. And so we're creating reports. We're creating drawings as engineers. And maybe sometimes, we're creating a 3D model. This is obviously not the model that the designer drafter will need, or it may not be at the same level as detail. So the drafter or the designer, whatever you may refer to them as, may be using Revit with some add-ons or still may be using AutoCAD also for Rebar placement. So they may be creating Revit to collaborate with other disciplines, but sometimes they're still doing their drawings of Rebar placement in 2D.
So this is a general thing. Some of us may be more accelerated, like I said. And we found this quote, or we've been using this quote for a while. It's from Autodesk University maybe a couple years back. It says-- and we like it. It really highlights things. "Unless you have a very sophisticated modeling transfer application available between programs, you're stuck with maintaining two building information models-- one for your cross-disciplinary coordination"-- which was the Revit model that we had seen prior-- "and one for structural detailing"-- which may still be AutoCAD in certain cases. "Multiply that with the open BIM exchange format IFC, and your original world of pain now looks like the Bahamas." So it highlights things, and we like it. So it signifies things well.
So we're going to look at it more of a point of view sort of way. We said the engineer's using several softwares, and he may be creating a model. But chances are he's using a stick model, not using a true alignment. This is not useful for the detail or the drafter, because you don't have the true placement of things, which they need. This is creating definitely big inconsistencies in the workflow.
And the things that are created by the engineer are results and documentation. They're not BIM. They're resistance diagrams, reports, to show that the model is sufficient and resists, based on code. And these are maybe some other associated documents. But these are definitely not BIM, which creates a disconnected workflow. That means there's a lot of repetition and replication of your model between disciplines. This means that there's potential errors and a lot of time wasted. And so these are things that we know already about the BIM.
So we're not using the data yet. And so some of us, this may be a conscious decision, and some of us may be more of a less conscious decision. Why is that? So some of us may have tried BIM workflow and seen that it was maybe too much work, or it wasn't what we wanted it to be. So that they decided, OK, you know what? We're going to put it aside. Our workflow was working well. We're stuck in kind of our old slippers, which are comfortable.
And some of us, it's more of a non-conscious decision, because we don't know where to start. What's the best format? What's the methodology? Do we want the detail or the architect to start in the model? So this is a process that's involved in there, that they need to look at.
If we look at things on the drafter side of things, we're looking at a BIM workflow that's only basic information-- geometry, cross-sections, materials, at best, sometimes. But we're not sending more information, more detailed information, and we're definitely not sending Rebar placement. So the engineers, we said, were creating documentation. This works both ways. The engineer is creating the documentation that's useful just for him, but not for the detailer or drafter, which means that they have to interpret the results, and work things, and figure it out.
Sometimes they're creating their reinforced concrete in 2D, which is a disconnected workflow, which means that if changes need to be made to the Rebar, they have to do them manually. It's not connected to your 3D models. So it's a disconnect. And if they are creating 2D drawings and 3D, and a 3D model, and they're creating their reinforced concrete-- and we're going to see this in the next workflow-- it's a long process. It's doable, but kind of a long, tedious process. So
If we look at that, what is a workflow with Revit and Rebar placement, we're starting with our model, which is easy enough. We're creating a 3D model. We're creating cross sections and definitions that go along with this, our families that are defined. We're creating 2D cuts. These 2D cuts are twofold, one to create your drawings and one for your Rebar placement.
So that's the next step, is we're placing Rebar in a 2D view. So it's kind of a bit more difficult. That 2D view, we could see it here. You add your Rebar. You add your labels. You add your dimensions. With that, you're getting a 3D cage. So you're still doing things in 2D to get to 3D. And then, with those 2D cuts, like we are seeing over here, you could put them into a drawing. So that's what's happening, if you're doing things in a 3D view in the best case scenario.
So we're going to talk about incorporating the data-rich intelligence. We're going to look at incorporating the structural engineering model. What does that mean? So we have our Revit model. The model can be transferred through simple add-ons. We have the power pack or the BIM connect, which is transferring our Revit model to software that will do an analysis in there-- analysis or design. And you could see it's producing shear diagrams, moment, bending moments, displacements-- everything that we need to know as engineers.
And this data is actually very pertinent. And we can bring it back into Revit. Our finite element analysis results could be imported back into Revit. And I'll show you why we'd want to do that, in the next step of things, and the second level.
This is obviously important to look at. It keeps things centralized, with your analytical model. Your analytical model will have and store things. And some of us may have already worked with this and seen it. But the analytic model stores a lot of good information and conditions, bending moments, results on supports at the base for your foundation design. And this will all be utilized for creating and designing your Rebar, using the BIM designers. So this is stuff that's important. So there's a lot of good information in Revit that we can save, and we can keep this all centralized in one specific model.
We're going to look now at our second level of things-- benefiting from the structural engineering model data. So we were looking at importing our finite element analysis results and what does that mean. What are we going to do with that information?
So we have our model. We imported our results. With those results, we can define our hypotheses as engineers-- our concrete cover, which Rebar is available to us for transversal or longitudinal. We have some assumptions that, as engineers, we need to define in there. And then we could easily just click Calculate, and we'll have a Rebar placement, a 3D cage that's automatically generated.
And what does this mean? We have a design that's to code. With this, we could generate a report. This report is useful for the engineer to make sure that it's to code, that it's satisfying all of our requirements. And it's showing calculations. So we have ACI in there. We have the 823 for Canadians, so American Canadian, and we have Euro code, as well-- so a bit of transparency so that we could troubleshoot in case something is not being designed properly. We have our clauses, which are highlighted in there, and we have a full, detailed report.
And so the next two things you'll see on this slide are pertinent for step three, our third level, where we're creating schedules and lists, as well as our 2D views, which are still important. And we could automatically-- we can generate our lists here, and we can generate our drawings automatically. Because we skip the step of creating the 2D view-- because we're not creating Rebar in 2D anymore, we're creating it automatically in 3D-- we need to still generate our drawings. And we have an automatic generator that will do that in there.
So this was purposely done that we have a different color. We're going to do a little sidebar here. We're going to look at what would happen if I didn't have a software that transferred engineering data. What does that mean? Can I still use the BIM designers, and if so, how? Well, I could enter my loads manually. If I'm using another software that's creating bending moments and shear and all those excellent information that we need as engineers, we could enter those loads manually into our software.
And so here we have a simple example. We have a beam that's-- we're importing a uniformly distributed load. We can import concentrated loads, trapezoidal loads. We can create really the same scenario that our analysis solution has been producing for us, and we can define our assumptions, like I had mentioned-- engineering assumptions, Rebar assumptions.
And we can still utilize the calculation. Just we're putting in manually our Rebar and manually our code, our loads. And we're still producing a 3D Rebar, based on that, on those loads, and those combinations that we've created in the software.
Let's go back to our workflow of importing those results. We're importing the finite element results. We're benefiting from the engineering data that's stored in there to do a true BIM connected workflow for Rebar generation. So like we had seen, we have results in here that are stored in Revit. We can visualize those results in Revit. And some of this we're going to see live. Joseph is going to show us this live, in an actual model, and here we go.
JOSEPH PAIS: Thank you, Michael. OK. So in this first step of the presentation-- so I wish to welcome this Revit model. So as Michael, as Michael explained before, this model-- so here we have the descriptive model. So it's a building with the first floor on concrete, on the steel structure of other concrete part. And this model is obviously including the analytical definition of the geometry.
So here, for example, if I go to an analytical view-- so we see the model, OK? So the analytical definition is done automatically by Revit. You just need to fine-tune the model, define, for example, the boundary conditions on the beams. So you can work on the analytical definition of each member.
Also, on this model, to achieve the workflow Michael just spoke about, we created loads. So in Revit, you can manage the load cases. So you can create as much load cases as you want. You can apply the loads on the model, and then make the link with a FEM system that will calculate the global structure, for you to be able to store back the results in Revit.
To achieve this workflow, what you need to install over your Revit is the structural analysis toolkit. So that's another one provided by Autodesk. So you can find it on the Autodesk app store. So it's for free. Just log in with your Autodesk account. And then, you will have, as you can see here, at the end of the Analyze Ribbon in Revit, you will have tools to-- you have the Resource manager and the Results explorer.
So for example, if I just display the first floor-- so the analytical definition of the concrete menders-- here, you have the Results Manager. So from here, you can see the different set of results, what we call the results packages, that are stored in your Revit model. So you can store different results packages if you iterate several times on a model, on the project.
And then you can explore directly in Revit. You can, for example here, display the bending moments on the beams, like that. So you see the values coming directly from the FEM system. Or you can, for example here, decide to [? post ?] process-- for example, the actions-- the reactions on [? support. ?] So this engineering data, which is stored within the BIM model in Revit. I will use it to automate the 3D Rebar generation, using the BIM designers and designing all the concrete numbers.
So for that, I am just coming to this view. And the first thing I need to do-- so when you install the BIM designers over Revit, you get the specific ribbon called Greater Concrete Design, where you have different functions for the design part and for the detailing part. So we have two different kinds of tools, depending on who is using the BIM designers in Revit.
So now, if I want to design elements, the first thing I can do is, instead of defining manually the loads, as Michael said before, I will ask the system to import a FEM system-- a FEM results package stored in Revit. So here, I see the two systems. So I will select the second one, which is up-to-date. So you have all the information. That is very important on a workflow, on a beam workflow, to know when you created this package, at what time, and so on.
I just apply. And now from this moment, what is very interesting is that, if I select a column, for example, and I go to the load's definition, you will see that we get automatically all the load cases stored in Revit and all the internal forces. So I don't need to define them manually. They are already there.
And this is true for all the members, for all the concrete members, from the model. So if I take a beam, it's the same. I can go there. And here, for example, you can visualize the bending moments, the axial forces, all over the span. So that's quite useful, because from now, I can really automate the 3D design-driven [INAUDIBLE] generation.
For that, just select elements. For example, I can select those two elements. I, of course, as Michael said, I have to define the design assumptions, the reinforcement assumptions. Nothing is magic. Nothing is coming from the [? hut. ?] So I have [? two ?] here. So you click. You have all the design assumptions, depending on the design code you are applying.
So for example, you can change here the steel grade to design those columns. You can go also to the reinforcement assumptions. You have a different set of assumptions for the [INAUDIBLE], for the transversal bars. And you can set up your preferences to get the expected 3D Rebar cage. For example, here I can ask to extend the longitudinal bars up to the beam top face.
OK. So as soon as you have done this-- of course, I will not go through all the details, through all the details. But for example, selecting a beam, you will see that you have really plenty of options, so you can really manage, in detail, all your own design options, including, of course, the main reinforcements.
AUDIENCE: [INAUDIBLE]
MICHAEL CONTE: Can we dim the lights? [INAUDIBLE]
JOSEPH PAIS: OK.
MICHAEL CONTE: Sorry.
JOSEPH PAIS: Yeah. So you have options for the main bars. But you have also, you see, as you can see, the possibility to manage the [? anti-crack ?] reinforcements, the splice bars over supports-- so many advanced options.
OK. Now, what you can just do-- so as soon as you have the FEM results loaded, you just select multiple elements, go there, and push the Calculation button. So now the system is designing the elements and populating the 3D Rebar cage directly in the Revit model.
OK, so if I zoom in, you can see what we get. And it's really, it's really creating, obviously, a reinforcement, a Revit native reinforced Rebar objects, with all the properties as you can have if you model it manually.
AUDIENCE: I have a question.
MICHAEL CONTE: We'll do the questions at the end.
JOSEPH PAIS: Yeah, just keep it in mind.
MICHAEL CONTE: Keep it in mind, yeah.
JOSEPH PAIS: And we can come back on the questions after. OK, so also, what is important to know is that you are in Revit. So you have the 3D [INAUDIBLE] hosted on the elements. Also, you can use the BIM designers to edit, to change what you get from the design. For example, here, you can just select a column. And here, coding the reinforcement dialog, you will have the possibility to change everything, to adjust, depending on your needs.
For example, here, you see two Rebar sets on the column for the stirrups, for the transversal bar. So for example, here you can increase the number of bars, just to get stirrups over the beam here on the node. OK, so you can really access all the properties of the 3D design Rebar cage. And the same for the beam-- so as you can see, you have a lot of possibilities, a lot of details, to really manage your 3D Rebar cage with, really, as you want.
OK. Then here, we have done this portal. But OK, when you may also have continuous elements-- so it's the same, basically, as soon as you create a continuous beam. So here, I have a continuous beam with three spans. Here I have beams with cantilevers.
OK. Just select them, and ran the calculation. So the system will, of course, automatically take into account the continuity, place, top longitudinal bars over intermediate supports. In all the options, you can manage how you distribute the bending moments between supports and spans, and so on and so on. So you have a lot of options.
And if we zoom in, you can see-- for example, here-- the bars over the cantilever. If I zoom in the continuous beam, I see the bars over all the intermediate support, and so on.
MICHAEL CONTE: All right, so let's make this a little more interesting. Do you think you could put a hole in a beam for me?
JOSEPH PAIS: Yeah, sure, sure. So here, for example, what you need to understand is that the BIM designers relies on the geometry you define in Revit. OK, so with using the Revit families, the ready types, we map all the families with our system. So obviously, the system works with your own Revit families. You just need to do the mapping once, and then it's done.
And for the openings on the depressures, you have the possibility to create them with Revit. Of course, you need to use the Revit native object. But you can do the opposite. You can also use the BIM designers to speed up your modeling in Revit. For example, here, I selected this beam. I can call the geometry.
So basically, the BIM designer is loading the geometry from Revit. So I see here the [? band ?] lengths. I see the section of the beam. And I can [INAUDIBLE] an opening, or a depression, over this band.
So here, just [? had ?] the opening define the shape of the opening. You define the position of the opening, for example, five feet along the span, from the beginning of the span. On the vertical direction, I will put 8 inches. OK. Michael, just check if I make some mistakes on the imperial units, because I'm not used to this.
MICHAEL CONTE: It's good.
JOSEPH PAIS: OK. So 20 and 8, for example, OK? You can also generate a [? depressure. ?] So you have different possibilities. For example, on the bottom [INAUDIBLE] on the right side of the span, you can define the length and the height of the depth of the [? depressure. ?]
OK. So as soon as you do it, then you see that you have-- you see, in the Revit objects, you have the opening. OK, so that's also a possibility. Even without speaking about Rebar, if you just want to quickly create an opening inside the element, just use this tool.
OK, then after, what I need to do-- I can select, again, the beam, redo the calculation, and then the BIM designer module will regenerate a 3D Rebar cage, taking into account those features on the beam-- so taking into account the [? depressure ?] on the opening inside the element. You're OK with it?
MICHAEL CONTE: Yeah, it looks good. How can I make sure that it's designed to code? If I am an engineer, I want to make sure that it's designed to the right code and that I'm satisfying the requirements.
JOSEPH PAIS: OK, first, I showed you that, when you want to design an element, you select the element. You code the design assumptions dialog, or the reinforcement assumption dialog. Obviously, all those assumptions are depending on the design code you apply. So the first thing you need to do on your Revit project is go to the localization dialog here and just set in the system which design code you want to apply.
So for example, here we are applying the ACI with the imperial version. We have also the metric one. We have the Canadian codes, the Euro codes-- so you can choose whatever you want. And also, here, another thing is that you can define which-- OK, it's coming. You can define which design report template you want to apply to justify a column, to justify a beam, or whatever.
So here, we have different templates, the detailed, the standard, the synthetic templates. So we'll select the most complete one. You would just select a beam. So you select the host element. And here, you have the possibility to generate a report. So you can create reports in PDF, in DOC files, or you can just preview the report before printing it. So here, it may take some seconds, because the system is loading all the results and producing a very detailed report.
So here, I just selected the most detailed one. So you will see, I will have, I don't know, 10s of pages, maybe 20 pages for this beam. And you will get, really, a lot of results. OK, so get it, and we'll just increase a little bit.
OK, so here, of course, it's a lot. It's 23 pages. I'm not saying that you will always generate 23 pages per beam, of course. But if, in case of, if you really want to go into details-- as you can see, maybe I can zoom in a little bit more-- you have all the assumptions. And it's really something that you should write as manually, as an engineer.
For example, references to the code, the material properties, you have tables with all the values. You have diagrams, bending moment diagrams, traces, shear diagrams. And because I asked for the detailed calculation, you will have the detailed, really detailed, calculation on the worst points of the span. So you can really go in the details of the design. So you have everything to justify how you got this 3D Rebar cage.
Also, something else you can do, you can get some graphical results. For example, you can select a column and go here and code the diagram to [? post ?] process the design results graphically. So for example, here, I'm just getting interaction curves on the column. And for example, thanks to this, I can see that the column is a bit over-designed. So I can optimize the design of these columns, because the maximum ratio is around 14%. So that's the way you can justify the design results.
MICHAEL CONTE: Perfect. So I'm used to doing a group design. If my values differ by a couple of kips, is there a way of grouping elements, either through loads or to a cross-sectional area, to group them together, to design them one shot?
JOSEPH PAIS: Yeah, sure, sure. For sure, it makes no sense to manage those design assumptions element by element, even if you can do it on a multiple selection. There are two ways to really optimize your Rebar project. The first, you can create design templates. That's very important. I don't need to apply the design options every time. Just create templates and apply them on the fly.
And the most important possibility is that you can group elements. So the grouping in Revit is based on the family and the type. So you should have the same types, so the same materials. But elements grouped in a design group can have. obviously, different loads. And we run the envelope calculation. So we do the envelope of the theoretical reinforcements.
So here, for example, to create a design group-- so you see that I have different types, so including some specific Revit families for footings with slopes. That's those specific Revit families are coming with the BIM designers. And for example, here, I can select the four round columns. And here, I have functions to create a design group. When you create a design group, you can say, OK, I want to initialize the design, applying a design template from one of the elements selected. And I can give a name.
So for example, I will call it Column round, for example, OK? So when you have done this, the Dashboard is telling you OK, you created an element. Here you can see all the elements included in the design group. And of course, you can manage all the elements, remove elements from the group, and so on.
To prepare these presentations, do not create all the design groups manually. That's not very interesting. I created already some groups. So for example, if I select some of those elements, I'm calling the Dashboard here. You will see that I already have different groups for the footings. I have a group for the [INAUDIBLE] column sections, and so on.
So now, why it's interesting-- just keep in mind that, on my Revit model, I have all the FEM results loaded in the model. So now, what I can do, I can just select, for example, one square column, one round column, one footing, another type of footings, the section columns. Just push the button, and now lets the system running.
So what is the system is doing is designing the worst element in the group. How we ran the calculation on each member-- we calculated the theoretical reinforcements for each member, and we make the envelope of the theoretical reinforcements. Then, we produce the same 3D Rebar cage for all elements from the group. So that's what Revit is doing now, is populating. In fact, the BIM designers are populating the 3D Rebar cages inside the elements.
And here you see you have the Dashboard. That's always very important, to see that where I am standing. So they are calculated. And here, you see you get the 3D Rebar cages on all the elements. OK, and obviously, the Rebar cage of this [? L ?] section column is strictly identical with this one. So that's the way you can populate the 3D Rebar inside the model.
Just before giving back the mic to Michael-- the [INAUDIBLE] Michael, also something important, because Michael was speaking about data. OK. We populate the 3D Rebar cages. That's one thing.
But also, if you select an element here-- Michael will go more in the details in a few minutes about that-- we are also storing on the elements, on the objects, some design parameters. OK? And we'll see why it's useful-- for example, the array diameter and so on. OK, so Michael, I give you back the presentation.
MICHAEL CONTE: Perfect. So we're going to now utilize the "I" in BIM, creating design drawings and schedules. So Joseph had highlighted the information. But what we can do is, with this beam, we could automatically generate a drawing that comes along with it. We simply pick the element we want. We create a drawing. It creates that the 2D cuts and creates the 2D cuts, the two sections of 2D cuts, and adds them to a sheet automatically.
With that, we also could create schedules and lists. So these elements, these Rebars are true Rebar in Revit. And we could create whatever lists we like, using the information that is available to us.
We could also take these Rebars and assign them to a specific sheet, as we're doing here. And we could take the schemas or the drawings, the images, and add them to our Rebar schedule. So there's more than just generation of Rebar happening here. It's all the documentation that comes along with it.
JOSEPH PAIS: Yeah, so just to illustrate this point, back in Revit-- OK, so for example, I take a beam. So first, you can use the BIM designers to boost, to speed up your process, producing views and drawings within Revit. OK, so for example, I select this element. First, of course, you can, with the BIM designers, you can use all the Revit templates you have created for your Rebar project.
So here, just go there. So here, you can define templates for beams, columns, footings. Here, we have a set of templates. But basically, you can browse your computer and just load the Revit file, which include the notations you want to apply-- scales, forms, and whatever. So you just load your Revit template just to get the expected layout; the same for the title block and the same for the bar schedules. We will speak about the bar schedules within seconds.
And then, just press the button to generate the drawing. Generate drawing means that the system will, according the template-- the Revit template-- in the Revit template, you define how many sections, how many detailed views you want to generate automatically. OK? The system is now doing it. So it's first creating those detailed views.
So for example, here you have the elevation. Of course, we are in Revit, so you can fine-tune or fix the small glitches you may find-- for example, just, I don't know, moving this tab, for example. And you see that you get this elevation automatically in seconds. So you have the sections, so different sections with different level of details.
And here, we have a drawing, a drawing sheet, including all those sections. The content of the drawing, again, is nothing is out-coded. Everything is coming from your Revit template. So it's up to you to say, OK, I just want one view. I don't want three section views, or whatever. OK, you set, in the templates, the level of details that you want to achieve.
Then, when you have this, what we want to do-- so you have also tools to help you to schedule the quantities, the Rebars. And we have two interesting tools. So we'll not show you all the tools, but that's the two main ones. The first one is to be able to assign a set of bars to a drawing sheet, [? or ?] [? else ?] Revit will schedule everything.
So in this model, I created here a Rebar schedule, as you can see. But for the moment, this Rebar schedule is scheduling the entire model. So the first thing I can do, I can go to the elevation. I can select everything. And here I have a function, Assign to Sheet. Basically, this function is-- I just select an existing drawing sheet. I press OK. So I have selected the bars. I assign to a sheet, to a different sheet, those bars.
And then what it's doing, it's adding a parameter in the properties of the bar. So that's a shared parameter, P55. And now, with this parameter, I can go back to the Rebar schedule, and I can filter the Rebar schedule-- sorry, first, I need to add this parameter in the schedule. So I will add the J sheet parameter. Then I will filter on it.
So for example, equals to P55, OK? I can just hide this parameter, because I use this field just to filter the content of my Rebar schedule. And then I press OK, and you will see that-- sorry. Now the Rebar schedule is only scheduling what I defined.
Also, something else you can do-- I can add another field, which is called image Revit [INAUDIBLE]-- yeah. I'm looking for the-- ah, it's already there-- sorry.
OK. So I will put it at the end. OK. So I have the image. And here, what you can do, you can also, for example, again select all the bars you want. And then here, you have a function, Schedule Schema. So basically, it's creating all the bending schemas with an hyperlink to the element. So the hyperlink is just because, then, if you change the bar, the schema is automatically updated.
So now it's doing the job. So in a few seconds, I will have a message that confirm the creation of the schemas. OK. And then, now, in the Rebar schedule, you have, as you can see here, all the schemas generated with the hyperlinks.
So why it's really useful is because now, if I'm coming back to my drawing, I can just drag and drop the Rebar schedule on it. OK, so I can place it here, for example. I can maybe drag it here, like that. OK, and then, you see you get the Rebar schedule with all the bending schemas. OK?
So as you can see, you can also use the BIM designers, not just to design members to populate 3D Rebar cages, but you have also tools dedicated to the detailing. And those tools can be applied on any Revit Rebar. If you take a strange shaped column, you place manual Rebars inside, you can use those tools to create, to automate the schedules' generation.
MICHAEL CONTE: So now we're looking at monitoring our Rebar project. So we're looking at-- Joseph was showing the 3D cage. He showed that there is a lot of good information that's produced here by the BIM designers, things that are important for the constructability-- framework, form work, or amount of Rebar, the weight of reinforcement. This is information that is created in the BIM designers and, once again, that famous "i" that we refer to.
With this, we can create our Revit lists. And so everything that has the G in front, it comes from the Graitec BIM designers. We're creating-- this is the list that was created. We could link to Excel. This is a dynamic link that is bi-directional. It's not just a one-time generation of Excel.
So what happens is I could create-- this is just the information of creating-- the Excel, and we could send it to Excel, monitor our project. But we could also add columns and information. And like I said, it's a bi-directional link. It's a dynamic link that it'll take the information back into Revit.
The final part is centralizing the project design information to provide easy access for the extended team members. So Autodesk has a large portfolio of cloud-based solutions. They are there to help the communication, to help the coordination, and to help resolve problems easily. So there's a lot of information that we get. And this results in a faster, more efficient project delivery.
So we have a BIM 360 Team, that allows team members, the players of the team, to coordinate and make sure that things are well done, the documents, to make sure that there's revisions. And if there's changes that need to be made, the people that are making changes, Glue for interference or clash detection. And so we have a lot of information, a lot of coordination, that we can do in field, in case there are sometimes things that happen in that we can't catch before going on to the field. So Field is there to coordinate and find the resolution as quickly as possible, to get the information to the right people as fast as possible, to keep that information centralized, and everyone could use it.
And we also have A360 viewers. We created a 3D model and uploaded it. This is for free. And we created a QR code. Do you want to?
JOSEPH PAIS: Yeah, so basically, just in addition to what Michael said, what you need to know-- maybe you already know-- is that the A360 drive and the A360 viewer are free. So basically, you can share a Revit model, including the 3D Rebar model. You can share it with your customers. Just load it on the viewer, share the link, and your customer even don't need user account. You just need to click on the link and get the model.
So I did it just before the class, to not lose one or two minutes, the time to load it on the browser. But then, you can see you get the model. So basically, you can navigate through the model. You see you have different points of view to navigate. So it's very nice. You can select an element. You can hide the selected element, for example here.
Then you can see the 3D Rebar car. And it's not just a viewer, because if you select an element, really, you access, you see all the properties of the element. So it's really a way. You see the badger meters, the bar hooks, the bar lengths, and so on. So it's really a way to share the data with your customers or with the different stakeholders of the project.
And also, for example, you can sketch. And you can also load not only-- here, I have only the 3D view. Anyway, so you can also load the drawing views. So if you have a drawing view, you can load it also on the viewer, and you can sketch it, get any information from the 3D model.
As soon as you upload a model on A360 viewer, the model is available 30 days. So if we are back to the presentation, you can scan the QR code and scan it with your mobiles, for example. And you will be able to navigate through the model. Also, after AU, it will be available for 30 days. So at home, if you want to share and show it to your colleagues, you can do it. Just click on the link.
MICHAEL CONTE: I think we're running late on time. Is that it?
JOSEPH PAIS: No, it's OK. We still have 10 minutes, so we are fine.
MICHAEL CONTE: Perfect, sounds great. So that brings us to our conclusion. Our BIM transfer is a true BIM transfer. It's a workflow with zero loss in data. We are transferring intelligence and information, not just geometry or cross-sections. We're sending results. We're generating more information when the Rebar is being placed, so that we could create our schedules. And when we look at our design, we're calculating a design based-- the reinforcement creating those 3D cages, based on-- and we're getting true design results. So we're getting our reports to ensure that, as the engineer, that they're right and they're to code. That includes Canada and US design codes.
We're creating the necessary views in the drawings with one simple click. So you create. You click Create drawing. It's creating your sheet, creating your 2D views, and applying it there. And it's utilizing the BIM information, like I said, that when you generate the Rebar, we're creating also information that goes along with that, to create our lists and create our bending schemas.
So just to come around full circle to end where we began, our learning objectives-- so our first learning objective was related and linked to that import, export, and synchronization of finite element results in the model. The next was to make sure that we did a true design for our 3D Rebar cages, creating and automatically generating those 3D Rebars, ensuring that they're designed to code. Finally, we created our schedules and lists that went along with it, also monitoring our project with the link to Excel. And then our final step was making sure that everyone that needed that information, using BIM 360, using BIM 360 teams, the team players had access to that information readily, so that we could solve problems quickly, and we could resolve them as quickly as possible.
So I thank you. You guys were a fantastic crowd. I hope you enjoyed it. I hope you learned something here. You could visit us at GRAITEC.com, and here's our logo, and Questions. The QR code is up. If you missed it before, you could scan it again. So yes?
AUDIENCE: Hi. Thanks so much for the presentation. It was really good. When you're putting the depressions in the underside of the deep phases, secretly, you do enough of them, and they're deep enough, you're actually going to start changing the [INAUDIBLE] analysis column. So when you do the mean calculate, is that pushing back, [INAUDIBLE] reanalyzing, or is it still using the original analysis results just to change the reinforcement design [INAUDIBLE] process?
MICHAEL CONTE: You're absolutely right. It is playing with the stiffness matrix, but it is using the analysis that was already launched prior. Essentially, the right workflow would be to go back into advanced design, make sure that your forces are [INAUDIBLE] and the stiffness matrix makes sense, and then bring back the right results. So the depressions, obviously, you wouldn't want to go too big, and then you would really cause yourself a problem.
AUDIENCE: [INAUDIBLE]
MICHAEL CONTE: No, that sounds great. Don't worry about it.
JOSEPH PAIS: And what is important is that, in the Revit results package-- so as soon as you make some geometrical changes, the results package turns to outdated. You'll still be able to use those results, but you have this message. So then, after, it's you to decide to make a loop again. Yeah?
AUDIENCE: [INAUDIBLE] analysis?
JOSEPH PAIS: Do what?
AUDIENCE: Seismic analysis [INAUDIBLE]?
JOSEPH PAIS: Yeah. In fact, the seismic analysis, it's the same. What you can do you, you can, for example, take the 3D model to the FEM system, run the seismic analysis, store back all the FEM results with the seismic load cases in Revit. And then, when you design the members, the members, according to design code-- for example, the ACI-- they are able, for sure. The design of the reinforcement quantities are considering the seismic forces. And we also take into account the constructive dispositions for the seismic for the [INAUDIBLE].
AUDIENCE: OK, so it doesn't do a concrete moment range like [? check and ?] all that stuff?
JOSEPH PAIS: Yeah, yeah.
AUDIENCE: OK. Do you guys do shear walls and check all that ?
JOSEPH PAIS: So shear walls, we are working on for the moment. So shear walls, you will have, unfortunately, to reinforce them manually in Revit, for the moment. We are working on the [INAUDIBLE] module that should be available middle of next year. But we are working on it, yeah. Yeah?
AUDIENCE: What's the average cost, roughly, for a [INAUDIBLE] of the [? Revit ?] package?
JOSEPH PAIS: Depends on the countries, but if you want the-- depend on the countries and because we have some factors. And we have two packages. We have one package including everything, design plus detailing. So it's around-- [INAUDIBLE] in the rear of the room-- it's around $4,000, $4,000 or $5,000.
AUDIENCE: [INAUDIBLE]
JOSEPH PAIS: OK. So I didn't say a mistake. But after, if you have-- because, in your company, you may have draftmen using Revit, engineers maybe using Revit. Not sure. So we have also a detailing package, which is cheaper, which is a bit less than $2,000, where are you access all the detailing part-- so the possibility to generate 3D rebar cages, defining parameters, schedule quantities, hard bending details, and so on. Yep?
AUDIENCE: You said, shear walls [INAUDIBLE].
JOSEPH PAIS: You mean [INAUDIBLE]?
MICHAEL CONTE: No, out of plane. So just a basic wall that's not taking any forces-- no. The shear wall will be the next one that takes in the loads.
JOSEPH PAIS: The shear wall module will take over-- will take both. Yeah?
AUDIENCE: Does the BIM designer work with the [INAUDIBLE] beams and [INAUDIBLE]?
JOSEPH PAIS: At the moment, the sloped beams, yes; the [INAUDIBLE] beams, not yet.
AUDIENCE: OK. And how it works with other [INAUDIBLE], such as [INAUDIBLE]?
JOSEPH PAIS: In fact, the BIM designers are not connected to a FEM system. The idea of the workflow is that-- the first step is linking Revit with a FEM results package. So for example, let's take Robot. You can use Revit, link to Robot. Robot is saving back the results in Revit, and BIM designers are applying those results. So--
AUDIENCE: So it works with any analysis package.
JOSEPH PAIS: Yeah, with any analysis package which is able to store FEM results in Revit, it works.
AUDIENCE: Thank you.
JOSEPH PAIS: Yeah, welcome. Yeah?
AUDIENCE: Question on the-- you said about the fabrication. You didn't-- [INAUDIBLE]?
JOSEPH PAIS: Yes. So yes, you can. In fact, for the moment, we don't do it automatically. That's also something we are working on, at least for the beams to be able to define the maximum bar lengths and to automatically split the bars. But as soon as you have the 3D Rebar cage in Revit, then you can do it in Revit. For example, you can--
AUDIENCE: Do you have to do it manually after?
JOSEPH PAIS: Yeah, yes, for the moment, yes, unfortunately.
AUDIENCE: Does it group the bars types together?
JOSEPH PAIS: For the moment, we don't use the groups. That's also something we are thinking about. For example, when you create, when you create design groups-- so you define the 3D rebar cage on identical elements. For the moment, it's independent 3D rebar cages. So they are not groups. So then you also have to group them, using Revit functions. And then, after, for sure, if it's groups, as soon as you change something, it's populating the change on all the elements.
AUDIENCE: [INAUDIBLE]
JOSEPH PAIS: The class detections are rendered either in Revit, but with some limitations, either in Navisworks. Or also, something that Michael said, you can do it in BIM 360 Glue.
MICHAEL CONTE: [INAUDIBLE].
JOSEPH PAIS: Yeah, yeah, yeah, yeah. Yeah, after, what is very nice-- if you use BIM 360 Glue to do the clash detections, you can filter. For example, you can say, OK, I want just to detect the clashes on big bars, on big diameters, not on small diameters, because I don't care, things like that. But this is functionalities from the Autodesk ecosystem. Yeah?
AUDIENCE: [INAUDIBLE] the outputs placed inside Revit, like just the [INAUDIBLE]?
JOSEPH PAIS: Yeah, yeah. In fact, after-- there is no limitation on Revit side. As soon as we have the 3D rebar cages in Revit, you can do really whatever you want. If you want to change, to adjust, the position of the bars, to avoid clashes, but keeping the design, then you should do it, not moving the bars manually in Revit. But for example, coding-- you saw it very quickly-- coding the dialogue, changing the position of the bars inside this dialogue, and then, as soon as you validate, the BIM designers is running a new design and telling you, it's OK. You are fitting the design code checks on it. For the moment, if you do the changes manually in Revit, then you cut the link between Revit and the BIM designer module.
AUDIENCE: So I will not be able to recheck online?
JOSEPH PAIS: Not for the moment, yes.
AUDIENCE: OK. So by by the way, are you going to plan to support the [INAUDIBLE] soon?
JOSEPH PAIS: Yeah, yeah, yeah, we are working on it, yeah. We should. We should, but I cannot promise you. Maybe AU next year. Yeah, maybe one or two more questions.
AUDIENCE: Does it do anything else [INAUDIBLE]? Does is do background construction?
JOSEPH PAIS: This is on your FEM side, so it depends on your FEM software.
MICHAEL CONTE: It's finite element analysis.
JOSEPH PAIS: OK.
AUDIENCE: OK, so that's what you guys meant by a [INAUDIBLE].
JOSEPH PAIS: Yeah, yeah.
MICHAEL CONTE: Well, we have a software. We have a software called Advanced Design, that does do P deltas in the nonlinearities, yes. And those results are imported into the BIM designer. So today, we were more talking about the BIM designer section. That's why your question threw us off. But Advanced Design, the analysis solution does do P deltas.
AUDIENCE: OK. So it's software-- [INAUDIBLE].
MICHAEL CONTE: Exactly, yeah.
AUDIENCE: [INAUDIBLE] software [INAUDIBLE].
JOSEPH PAIS: Yeah, exactly, yeah.
MICHAEL CONTE: Thank you very much.
JOSEPH PAIS: Thank you, guys.
MICHAEL CONTE: Thank you, everybody.
JOSEPH PAIS: And enjoy AU.
