Make It a Round-Trip: Workflow from Design to Construction Site with BIM 360 Docs

JULIEN DROUET: First, good morning, everyone. So thank you for joining. So it was not the best time right after the party. And so we do appreciate to see so many people in our room. My name is Julien Drouet. I'm based in Paris. So maybe you could guess that with my accent. I'm a Senior Technical Specialist focused on MEP, MEP fabrication, and construction. And so for this session, I will be with Cyrille Fauvel. So Cyrille, maybe if you want to introduce yourself.

CYRILLE FAUVEL: Sorry for that. We only have two microphones. So I'm French as well but not based in Paris. I'm based in Brest, so a little city in the west of France. I'm a developer and I'm working mainly on the Forge API at AutoDesk.

ALEXANDRE MIHALACHE: And I'm Alex, also based in France, and my focus is I'm a technical specialist for AEC collaboration.

JULIEN DROUET: So 14 this session, we wanted to provide you a workflow with imaging based first on a real project. So what is important to keep in mind is that what you will see wasn't applied during the real project, but it could have been, actually, because everything is based on existing solution except the end. And then what you will see will be our proposed workflow. And for this workflow, we wanted to cover the construction phase from the Tender to the installation.

We use BIM 360 Docs of the common data environment, and we wanted to provide something highlighting how interesting it could be for all the design team, the construction companies to use all together BIM 360 as the common data BIM 360 Docs [INAUDIBLE] common data environment. And as I'm an MEP specialist, I'm focused on the MEP stuff. And you will see how to use Revit, MEP, and MEP Fabrication solution just to be applied during this construction phase from the Tender to the installation.

So the agenda for this session. So we split it in four parts, plus the Q&A session at the end. And we will see first the Tender and pre-construction phase and explain you how to use Docs an MEP Fabrication and Revit MEP during these phases. Then it will be more focused on MEP Fabrication. And I will try to highlight what can be positive in the use of MEP Fabrication for optimization.

And of course, the fabrication of each duct work elements. We will have a short part about coordination. Once again, just to highlight the different features provided by MEP Fabrication for the construction and for the coordination. And the last part will be the cherry on the cake. So we asked Cyrille to think about a development based on Forge that will bring to the construction site all the advantages of using Docs MEP Fabrication to provide something to track elements on the construction site. And then we will be able to answer the question, hopefully.

So first the Tender and pre-construction So for the Tender, so the [INAUDIBLE] was to focus on construction project type, design, bid, build. So because we think it's the most complicated in what we wanted to show involving the more people, the more different companies. So if we would have taken an integrated project delivery, certainly it would have been easier for each exchange and collaboration. So that's why we focused on this kind of project type. And as we said, we focused on Tender and the construction phase. So the design phase is supposed to be done. And we won't focus for this session on the operation and maintenance phases neither.

The project we are using, as I said, actually, it's a real project. So the models and document we used for this presentation are part of the green overlay project. This is a project. Schneider Electric asked and built. I think it was delivered in April this year. So you have the opportunity to have more information on this project on the Schneider booth. So they have a dedicated booth on this project. And they kindly provided their data for [INAUDIBLE] purpose.

So this project is composed of two of his buildings. It's located in Grenoble in the southeast of France in the Alps. And we will only focus on one of these two buildings, which is called the [INAUDIBLE]. And the next screenshots will show you a few details about this project. So the amount it's under 20,000 euros.

So it's a design build. And you have the different kind of information. And here is an overview. It's the short overview of how it looks like. And the MEP. So the HVAC, only HVAC on this screenshot. So it's a real project. Really interesting database for [INAUDIBLE] purpose. So Alex, go ahead.

ALEXANDRE MIHALACHE: OK. So I just wanted to take two minutes to talk about BIM 360 Docs here. A very short description and how we used the different workspaces we have in BIM 360 Docs. So that's basically just a suggestion and our choice that could be, of course, adjusted to any type of contract needs, et cetera.

So we have here, as you can see, the two workspaces. One is red and one is green. They are called plans. So the first one here is called plans and the other one is project files. We use the project files, just as you can see here in the bold sentence here, bold characters here, we use it as our work in progress data. So basically all the Revit models you'll see in the next steps you will also use it for the coordination models, the Navisworks models. And we can actually manage any type of file in this workspace. So you have a screen capture here also with our hierarchy of files.

And then we also have the plans, the plants folder. We used for basically Tender and building purpose. So this is the more official folder, I would say. So this is where you transmit the different files, data, to subcontractors, to the general contractor as we will see in the next few minutes. So here we can manage Revit files, 2D views, 3D views, but also plans from Revit, intelligent plans from the Revit database files.

But also we didn't [INAUDIBLE] for this session, but we could use AutoCAD drawings. And we will also show you that we have a very nice way to manage PDF files as well. Not only plans, but also documents, as they are omnipresent, I would say, on the different sites in construction operations. We could also manage DWF files, of course.

So again, that's only my second slide about BIM 360 Docs here and then we go to the workflow. We have the possibility for administration to, of course, invite people here. So you can see my nice image here. And the emails, the different persons emails. And what's important also, so that's the administrative view, is to assign companies to assign the users to different companies. So we did assign users to the general contractors or AutoDesk or whatever. And also we can create groups. Groups, for example, the design teams, general contractors, subcontractors, et cetera. And this will be important for permissions later.

So this is how you create. And the manager sees the different companies that we have created for this session, for example. And also, you could see here how easy it is to invite the different members. You just type the [INAUDIBLE] address once they're in the project and then assign a company and eventually a role or a group, which again, will be very important for the different permission settings on our [INAUDIBLE].

So that's the next one. And we wanted to show you that we can easily assign permission per user, per company, or role. I mean, it's just two clicks. Don't have to have a lot of knowledge about permissions. Everybody can do that. Just invite people into the specific folder and then assign the permissions for a user role or company.

And we also added a short description here. For example, upload only could be for subcontractors. So they could just upload their bidding or the general contractor. They could just upload the bidding and maybe not see the documents the other subcontractors uploaded. So that's pretty easy. Very easy to set up. And we just wanted to give you a glimpse of this.

JULIEN DROUET: So first video here. I think we need to click on it. Yeah. Thanks. We are in Revit. And we prepared the model and we can also publish the different-- this is where we choose the different views or plans to publish to BIM 360 Docs from Revit. And we imagine the workflow and we'll provide the dynamic script. We imagine a workflow with a dynamic script to automate that and to choose a different sheets or plans or 3D views to upload to BIM 360 Docs from Revit.

So from this model here, that's the upload process where we could easily upload linked files. So we had six disciplines in this model. So as you can see here. And we just uploaded six different disciplines as linked files. So we can have the information in context. Not only on the 3D views or the plans, but also in a split view, which is possible now in BIM 360 Docs, where you can see the 3D view, the 3D aspect, and also the 2D plans. I can click on an object. I can see it on the 2D view and, of course, browse the properties of this object. So I have the information in context again.

So in this workflow, I'm the owner. I'm the owner now. So it would be Schneider Electric. And I would need to interact with my design team using a feature called Issues. And I will ask my design team to add the section, for example, to the different models here. You can also see that I can add a comment at the location. Of course, assign it to my design team. So I can ask them kind of officially to add the model.

And also I can put into the system that I need a due date, for example, for this change on the drawings, for example. So this is the view of my design team who receives the request, basically. And can now go back into the design process and, as usual, add the section to one of the drawings to explain a specific problem or a specific area on the project.

You can see I can easily interact here and also provide an official response. So we can close this request. And you can also see. So I'm in the browser. You can also see sometimes my BIM 360 Docs is in French. So this could be applied on international projects. Everybody uses its internet browser in his or her own language. So that's very easy to use it on an international project.

So this is the workflow. You can see I can interact. So the owner and the design team can interact, ask questions, provide answers, and of course, even add link files if needed. For example, a PDF file to explain the different changes.

OK, so I told you about permissions in BIM 360 Docs. This is what we used. So for the next couple of minutes, we set up the system with one general contractor. Of course, in the Tender you would have many general contractors. We just chose one for our workflow, our example. We set up permissions. And of course, I also have these two profiles here, the project manager and the designer who are part of the design team. And you will see, we will show you the request for informations. And all these three profiles will be involved in this official request for information.

So another screenshot here showing you the different RFIs, the Requests For Information, available in BIM 360 Docs today. So it's pretty simple. We have somebody asking a question. Then the manager dispatches it to the right person in the design team who could bring the technical answer. This is what we wanted to show you. So the creator here is the general contractor. The manager will be my project manager from the design team. And then he will dispatch to what we call here a reviewer, which is the designer in the design team. Specialist. MEP specialist, I would say, HVAC specialist.

This is how the workflow looks. So the creator just asks a question, an official question. He submit it to the manager, who finds the right person to answer. Then he gets the answer, and then he provides the answer to the creator, which could be the general contractor, in our case, or a subcontractor.

So this is another video here showing you this RFI workflow, which is a bit more official than the issues we showed you earlier. So the general contractor here opens the model. I'm still using the web browser version of BIM 360 Docs. We use Chrome here. Opens the model and creates the RFI. What's important here, again, it's about context.

So he has the 3D view here. He can filter on the specific system, which is concerned about the question, I would say. And then we can add a title, add suggestions for the answer, and of course, add a specific person to ask the question to, and the due date. That is also important, because you will see that in the next steps, we also have email alerts. Basically the system tells you if you're late or not in the different RFIs.

So now we are seeing the project managers. So he's from the design team, right? And he reviews and looks for the right person to answer this specific type of question. So the question here was about the velocity of the systems in general in the HVAC models. So we can see that, again, every user, every group of users, can see the info in context without having to install anything. If they're not Revit users, they can just open the browser, connect. They have permissions on that folder and they can actually access the information in a very easy way.

So here we are the designer, again. We receive the RFI and we use this interface to first check the request and then provide maybe an official answer here. So this is important also because we will be able to, with this system, we'll be able to keep track of all the different changes and interactions on the documents.

So it adds another layer, I would say, in the context view I was telling you about a few minutes earlier. I'm the product manager now. I'm just basically here verifying that the answer was OK. And I can actually close the request for information. So this will mean that the answer will be provided officially to the subcontractor or the general contractor. In our case, it's the general contractor.

So this is the official answer. I receive an email. I just click on the link. I go straight to the right section in BIM 360 Docs. I can check the answer and adjust my bid according to the different velocities that the design team providing me.

OK, next step will be-- so we are, again, in pre-construction. And this is what we called bidding and detailing. So this is where general contractors or subcontractors will prepare their response, so their bidding, and of course, refine a bit more the detailed models.

So we are on the Tender and bidding documents here. We showed you on this screenshot the folder and subfolder system. So we are in the plans area of BIM 360 Docs now. So this is important. Those are the official documents, I would say. And we set up specific access rights for the general contractors. Or eventually, the subcontractors.

OK, so now let's consider that I am the MEP contractor for the GC I associate with. And I would like to be able to provide a price for all the MEP stuff I have to do. So in our projects, we will focus first on a dedicated area of the project. So for this video purpose, we won't do it for everything, because it would be much too long. And we will focus on one specific system. It's a return system. And so here we have the design model.

And we will use the MEP Fabrication features to convert it quickly so that I will be then able to get the price of total cost for all of this system. So I just select the system and use the converting tool inside MEP Fabrication. And it will convert each element into fabrication element, which are much more accurate or actually the level of detail of my model move from 200 to 400, more or less.

And once it is done, I can adjust it quickly by using the Revit feature to change a type of element, for instance. Then if I want to change the way this connection between the two ducts are done. So I will just add quickly a new tap. And then use the Revit feature to just reconnect everything so that I-- something really accurate based on fabrication elements. That will be then easier to estimate.

So once this work is done, I can also apply. So I think it's one of the new feature from the 2018 the [INAUDIBLE] version. So you can apply on fabrication element any kind of feature, for instance. And then you will get actually the same representation you had with design model.

And once it is done, I will then export it to the fabrication solution. So I create an MAG file. And this file will be then open in [INAUDIBLE]. So once again, the purpose is to get shortly a price to be able to answer to the general contractor and propose my bid price, actually.

So this is a very easy workflow from design to fabrication and get an accurate price for this system. But just consider that this could be applied for every single system you have in the global model. So here we have immediately in one click the price for this global system. And you can also check for each single part and get the breakdown cost for each element of your system. So at this stage, the goal was only to get quickly a price, but the most accurate I could for this phase.

But then I am lucky. I won the bid, the Tender, and I will now rework on the same system to optimize it and try to provide something that will be better and cheaper. So I will use the Revit MEP Fabrication feature to, for instance, remove all the small straight part that is nonsense to fabricate.

And I just, for instance, adapt the length of my elbow so that I will remove for the same system. I will be able to have the same system but with less parts, so which logically should cost less. Another focus is to try to get the most straight element that are exactly on the same length. So for instance, the specifications said that a straight element with the specification is 1.5 meter. I will try to have as much as I can this kind of element so that it will cost less to fabricate to have a lot of similar parts. So this work can be-- yes?

AUDIENCE: [INAUDIBLE]

JULIEN DROUET: By default, no. Yes. I think the question is if there is something in the program that is able to identify every small part to remove it quickly. So I would say by default, no. I guess that's something that could be done through Dynamo, for instance. That's something that we could ask also to our project manager team to provide. But also I think it's important to keep the contractor to have choice to do exactly what he wants. Sometimes it could be maybe more important for him to do on a way. So to have the choice is not a bad thing. But we could provide this kind of feature or create a Dynamo script to save time.

So let's move on. OK. Something important also when we think about the installation is to identify where are each element. So we can also number each element, create the views that will be useful later.

ALEXANDRE MIHALACHE: We did it, manually, but we could have used a Dynamo script for that.

JULIEN DROUET: Also for this part, for sure. And then once I have optimized my system, I recreate a new fabrication file. And just check first if it costs less as expected. And then this new MAG file will be used for fabrication purpose.

So a good thing is that I have only 74 parts. Previously I had 80, I think, if I correctly remember. And so here is the price we had previously. And now I close the previous job. Open the new one I created. And at this stage, I can get immediately the price to check. And yes, it's cheaper. So about 150 pounds for this system. So about 5%. It's not huge, but it's still interesting.

Now I move to CAMduct. So the next step will be to fabricate, of course, each element of the system. So I open the same file I created previously in CAMduct. So I get the list of each element. And I will nest all of this part on my sheets. So I think that the most impressive tool inside CAMduct is this algorithm able to nest very quickly and very smartly all the part development on sheets.

And then, of course, I will create the NC file to fit the cutting machine I will use. So there are different settings. So you just have to choose which machine you will use. It create the NC file. You can then visualize inside CAMduct the way each development part will be kept. So you have a kind of viewer for your NC file. And you can see quickly the way all of this cutting will be done.

And so actually relatively quickly, you could get all of this work done. And you create also some labels that you will stick on each element. And that's really important, because for the end of the presentation, we will use actually these kind of labels.

You can export it into a multi-sheet PDF file. And this PDF file will be stored on BIM 360 Docs as well. So you not only store the models, the plan and so on, but also all of this fabrication information that will be available on BIM 360 Docs during the installation phase. So something important also. You are able to I think you will speak about that later for the-- yeah, OK. [INTERPOSING VOICES]

ALEXANDRE MIHALACHE: I think I can take this one.

JULIEN DROUET: Yeah, go ahead.

ALEXANDRE MIHALACHE: OK. So that's a PDF OCR on BIM 360 Docs. So basically, we have character recognition. Usually we use it for recognizing the information in the template. And then we can use this information in the attributes of the many documents we could share on the BIM 360 Docs platform.

We use it for these labels Julien showed you for this workflow. You can see here that we are setting up the different, I mean, the character recognition on the number, just as an example. And we also created a new property on the sheets, on the plans, which is about weight. So we want to take this info and feed the different properties in the system.

So once we uploaded all these multi-page PDF file into Docs, we also get an alert. So we just click on the link and go ahead and review the publishing, because that's what we're talking about. And we can see, just as Julien showed you, the different pages of my PDF. So I think we had 86 something whatever. We had many pages of our PDF. And there were split by label and, of course, by number. And this is the property we created in BIM 360 Docs. We just created a manual property, the weight, and it automatically read the weight on the labels. So that's coordination. That's your stuff.

JULIEN DROUET: Yes. So I would say in parallel of this fabrication process, you have also, of course, to take care about coordination. And so I wanted to just to focus on the supports that you have to add in your model, because it's something needed.

And generally, most of the coordination issue that you have at the end of the coordination phase are coming from these reports because they are not so often modelized. And most of the time, you could have these kind of issues of coordination issues that are appearing at the end of this coordination phase. So MEP Fabrication features inside Revit provides you the capability to create really quickly and easily all the supports.

So here I just focused on two different systems. So the previous one and the one that is just besides. And I add my different hangers on these two systems. Quickly, but maybe too quickly. And to be sure that there is no coordination issue, I will, of course, use our preferred tool do so. So I will export this view with these two systems in the NWC format, so for Navisworks.

And in Navisworks, I will just check if there are some interference between, some clashes between hangers and ducts. Of course, I use the search set feature in Navisworks to quickly get my sets. And I launch. So I run the test between these two sets. And actually, yes. So I worked too fast. And I have five clashes to fix.

So with the switch back feature, I will go back to Revit. I quickly, of course, fix this kind of issue. We export a new version of my NWC and just check and see that these five issues, these five clashes I have, change their status. Now they are resolved. And yes, a question?

AUDIENCE: [INAUDIBLE]

JULIEN DROUET: Excuse me, could you repeat?

AUDIENCE: [INAUDIBLE]

JULIEN DROUET: Yes, we could have done. But actually, what I like to by using Navisworks is the search set tool that is not existing in Revit. And so in Revit, you will use the [INAUDIBLE] the category type.

And on my point of view, of course, when you just check between the two angles, so between angles and [INAUDIBLE], it's something easy you could do, I agree, in Revit. But if I would like to find quickly all the clash between the rectangular [INAUDIBLE] that have exactly this size and the hanger that are this shape, certainly the search set is something more powerful to proceed that the first thing.

And the second thing is that most of the time, the point of view you get when you create a clash easier to understand so that you can navigate. You have display features in Navisworks that are, on my point of view, better to understand and to fix. So that's a preference.

And the other thing is that, in that case, everything was done in Revit. If, for instance, I would have tried to find the clash between my MEP and my structural stuff, and if it's not a Revit file, Navisworks is maybe more relevant. So I agree in that case, we could have used a Revit interference check too. Yes?

AUDIENCE: [INAUDIBLE] Did you have to manually go to each clash then and check [INAUDIBLE] or did it automatically know [INAUDIBLE]?

JULIEN DROUET: Yeah, could you repeat and then I will repeat? Because it was a long one.

AUDIENCE: [INAUDIBLE] Then you go into your [INAUDIBLE]. Does it automatically recognize that those two elements are clashing?

JULIEN DROUET: Yes.

AUDIENCE: [INAUDIBLE]

JULIEN DROUET: So yeah, the question was when we use actually the Revit switch back and move back from one clash to the Revit environment when we fix it and back to Navisworks it seems that sometimes it's not automatically displayed as resolved. So when I created this video, it was automatic.

AUDIENCE: [INAUDIBLE]

JULIEN DROUET: The version, you mean?

AUDIENCE: [INAUDIBLE]

JULIEN DROUET: How do we switch? So Revit switch back is--

AUDIENCE: [INAUDIBLE]

JULIEN DROUET: Yes, yeah. Actually, I re-export and then I refresh in Navisworks. So the switch back allows me to get the right view whether the element is selected. Then I fix the issue. But then I don't use the Revit switch back button. I recreate a new NWC file. And then in Navisworks, I just refresh the project. Yes?

AUDIENCE: [INAUDIBLE]

JULIEN DROUET: So in that case, the Navisworks model, it also push on BIM 360 Docs. That's important. We are using the work in progress environment for that. So actually, we didn't use BIM 360 Glue for this demo. We could have. I guess with the next gen, this kind of workflow will be even more relevant for that.

So here is an overview of the coordination model in BIM 360 Glue where you can highlight easily the different elements and take profit from the BIM 360 features available. So that's it.

OK, so for this last part, we were thinking about a way actually to move forward with all these elements we have on BIM 360 Docs. So we have the design model. We have the fabrication model. We have different views, different plans, different labels. And we were thinking about a way to track elements on the construction site.

Of course, MEP Fabrication provide a tool which is called Tracker. But it's not linked to any kind of viewer or any kind of geometry. So we thought about a way, actually, to identify quickly when I scan a label that is stuck on a part. How I could display it in BIM 360 Docs [INAUDIBLE]. Actually how I could be easily informed where is the part, how to install, to get information on it. And we asked Cyrille if it could be possible to develop something based on Forge to get this possibility. So Cyrille.

CYRILLE FAUVEL: So yeah, with the mic it will be better. How many of you knows what Forge is? A couple. That's nice. So for those who don't know, Forge is a web platform API, so that's made for developers, which will allow you to access all the information that you store on BIM 360 Docs or any other web applications that Autodesk provide. It also has a set of APIs, so you can build application from that.

So as Julien was explaining that they created these QR codes that you can stamp on any component in your building. Not on the HVAC components. And for maintenance reason, it could be a very nice way to track items into your building and connect these items to BIM 360 Docs on your ERP system. So for example, if you have some electrical device which are faulty, you can scan the QR code and then goes directly to your ERP system to make an order for maintenance or make an order for replacement. So we want to apply that to this example as well.

And we wrote a very quick application that can run on your phone. And we'll use all the information from your BIM 360 account. And the application I'm going to show you is this application. And it was written in 30 minutes. So you'll see what you can do very, very quickly. So before I use my phone, I just want to show you quickly the application itself running on my desktop.

And this is exactly the image you saw previously. So you have the actual Revit model. Let me change the-- yeah, better for you. So you have the full 3D model available to you directly from a web application. As well as if you prefer to work in 2D and the drawing was provided, you can have the exact same experience in 2D.

So it's really flexible in the way how you want to bring your digital information on site. And what we're going to do from the phone, and here just to simulate I'm taking a picture of a QR code that is available on the component. Then I can go directly and find this element. Once I have it, I can load even more information from the BIM 360 Docs account. OK, so that runs on my Chrome browser on my Mac.

And now what we're going to do is try the same thing from my phone. And actually, if you want to try yourself, you could. But for technical Wi-Fi limitation here, I have my own Wi-Fi just to make sure that everything is working properly. And doesn't show? It was working. Yeah. So now what you see is my phone. So if I do it here, you can see that I have the exact same model. And now what I'm going to do is take a photo. Where is it? Here?

If I was on site, say I want to use this photo. And I want to select the item. And what you've seen on this left side is the photo I've been taken is displayed. So I can identify the element on site. So I can save this image back to BIM 360 Docs or to my ERP system if I want to. I have internal identifier of the item that has been generated by the fabrication tool.

And now if I want to receive more information about this particular item-- and remember, it could be anything, not only what we presented today. I can load. the PDF that is available to me. And then if I have more information on the data sheet, I could have some maintenance, historical information about what was done before, what I'm supposed to do, maybe some ERP system will tell me what I'm supposed to maintain on that item, and report information back to BIM 360 Docs or any of the system.

So that just to show use that to complete a workflow is that not only through that process you created information, but you can actually continue to use it after fabrication and installation. For maintenance reasons, could be [INAUDIBLE], could be anything you want. OK.

AUDIENCE: [INAUDIBLE]

CYRILLE FAUVEL: Yeah, exactly. So if you connect-- I don't know what kind of information system you have, but from the phone now, if I connect the phone to that information system, I can exactly do what you say.

AUDIENCE: [INAUDIBLE]

CYRILLE FAUVEL: Yeah. Absolutely. So that's really it about the demo. Maybe if you want to see the code, because I said it was done in 30 minutes. It's 50 lines of code to get all that experience. So it's very easy to write, very easy to deploy. For technical reason, again, I'm running everything local. So it means that I would be completely offline if I want or I could be connected to the system directly. So it's very flexible in the way you want to work with Forge. And if you have any question about the code and you want the application itself, we can easily share it. It's not a problem.

AUDIENCE: [INAUDIBLE]

CYRILLE FAUVEL: 50 lines of code. Actually, let me show you. You'll see the whole application. So it's one HTML and 50 lines of JavaScript code. So let's start with the HTML. So the HTML is actually a set of reference to script files. Oh, maybe it's a bit small. How can I change the resolution? Yeah, like this.

So a couple of references to the viewer, which is a Forge viewer. And this is a whole HTML body for running the app. OK? And the JavaScript file is this. Nothing very exciting, but it does the job, which is more important. So remember, it can work offline or connected to BIM 360 Docs on other information system. It's really a matter of defining what you want. There is a question here?

AUDIENCE: [INAUDIBLE]

CYRILLE FAUVEL: So the question is, can I access everything which is on BIM 360 Docs? The answer is yes and no. It depends. It depends of your privilege on BIM 360 Docs. So I'm an administrator, so I can access anything and I can override anything. But if you say this guy can only access item one to item 15, it can only see that. So you access only what you are supposed to see.

ALEXANDRE MIHALACHE: I would just like something about the way it's also working. So actually, we needed to create another Dynamo script we didn't show here to be able to bring back the information that is behind the QR code and to bring it back into Revit so that when you upload the Revit file on BIM 360 Docs you have access to this information.

So by default in a fabrication element, the QR code information are not visible in Revit. So we just added a kind of short script that involved one of our colleague, [INAUDIBLE]. She's unfortunately not with us. So it worked in a couple of minutes, this short Dynamo script, so that we were able to have the QR code in Revit and so in BIM 360 Docs.

CYRILLE FAUVEL: Yeah. And this is what I'm showing here, that the fabrication node you have here is a QR code that has been decoded on the left side. So you can see that all the properties you have in Revit are also available here. So you can enrich your model with more information as you wish to connect to other systems.

So for example, let's say you have an electrical device and you want to get from you say Schneider Electric? So Schneider Electric. So technical information about the device. If you have the link here, you can connect to Schneider Electric website and download the technical information sheet directly on your device. So it's really up to you how you want to build the experience.

AUDIENCE: Take a step back. Those PDFs were created in Revit from the fabrication?

JULIEN DROUET: It was created in fabric-- I think I created it in the CAMduct. So just by printing in PDF format the different labels. I think from the last to 2018.2 in Revit it's also possible to do so. So it's a new feature. So actually, I did it in CAMduct. But I could have done it from Revit as well.

AUDIENCE: [INAUDIBLE]

JULIEN DROUET: Yes, that's what I said. So actually the labels were created in CAMduct. Each part was associated with this QR code. But by default, when you look at the part in Revit, you don't have the QR code information by default. So that's why we created this script to bring it back to Revit. Because when you open the Revit file in BIM 360 Docs, you can have access to this QR code information.

CYRILLE FAUVEL: I think if we had a bit more time to do the things more a bit deeper, I would say, we would have connected the fabrication database to the Forge app. That would be, I think, the easiest and the more professional way to do it.

JULIEN DROUET: Other question, if you have? So thank you. Yeah, another question?

AUDIENCE: [INAUDIBLE]

JULIEN DROUET: I guess, yeah. For sure.

CYRILLE FAUVEL: We only have two mics. Sorry for that. So we I actually work with many people doing these kind of workflows. That's why we developed the example to show us that you can connect your digital information with people on site. So they can access not only the design information, but as well also maintenance and details about the same.

So we have another example which is based on [INAUDIBLE] where we have some IoT data where we display the IoT information. But we actually connect machine to the manufacturer that are sheets. So whenever you have to do a maintenance operation, you can connect [INAUDIBLE] from different system. So yeah, many people are implementing this kind of workflow nowadays. Whether they use a phone or tablet or something more funny for a couple of them. They try to use [INAUDIBLE] now as well. So [INAUDIBLE] operation on items. I hope I answer your question.

JULIEN DROUET: Yes?

AUDIENCE: Go back to the [INAUDIBLE] you added a little orange dot [INAUDIBLE]. Does that model element tell you if it changes or [INAUDIBLE]?

ALEXANDRE MIHALACHE: Well, we could comment on that RFI once we modified the element. Maybe with the element ID, or we could also consider some kind of Forge development like, I guess, and hope like another 20 lines and 30 minutes work from Forge. So that would be the way I would consider it.

Sorry, the question was, when I make a change in the model, does the RFI automatically understand the change, basically, on those specific object I made the change? The answer would be no, not automatically, but I could use comments or even consider doing some kind of Forge development on that.

JULIEN DROUET: And you have also this kind of information with the compare model too.

ALEXANDRE MIHALACHE: So should you have any more questions, we are here for a few minutes. Thank you very much for making the effort.
