- Vincent FredonVincent Fredon is an Autodesk Solution Engineer in AEC. He is an Infrastructure specialist working with all the Autodesk infra solutions and mainly Autodesk Civil 3D, InfraWorks and Navisworks. He is based in Paris. Vincent has worked 13 years for Engineering companies in the Infrastructure domain. He then moved to an Autodesk VAR (GraphLand) where he has been Trainer and Consultant for various enterprises and projects (road, rail, energy…) on different software and BIM processes implementation. During the last few years, he has developed a strong expertise in meeting the needs of French civil companies. Vincent also worked on the French Civil Country Kit and the Autodesk InfraWorks localization, as a contractor for Autodesk.
STEPHANE BLAMAIN: Just a small precision-- here we will see InfraWorks, Civil 3D, Revit, and AutoDesk Robot Structural Analysis. But we don't put in the detail because after it was too long as detail. And if we put RSA, some people don't know what is it. So we don't know put it. But I can show you, and we'll show it to after. We can start? OK.
OK, so we will see a class, how to use InfraWorks, Civil 3D, Revit for civil engineering. So what we will see in this session is a workflow. So after we'll see-- so now you have the PDF and the PPT, but in PDF, so no video. So after, we will see how to share this in video. Of course, it's recorded. So you can go on AU [INAUDIBLE] and have it. But maybe we will post it on our blog too, so maybe sometime it's easier. OK?
So we will see all this. And of course, this study is fictive, so it's not real. But all the manipulation we have done are real. OK? And we will show how to use star products. And that's why Robot is in there also, because internally it's not a star product. Even for me it's a star product.
So you will learn how to use InfraWorks, Civil 3D, Revit together. And we have some tips and tricks because sometimes it's not so cool as we can expect. And we learn better communication in-context visualization of the project, with a part of engineering to have accurate data. So, Vincent.
VINCENT FREDON: Oh.
STEPHANE BLAMAIN: You can introduce?
VINCENT FREDON: Yes, good morning, everybody. Thank you very much to be here with us this morning. I am Vincent Fredon. I am a technical sales AEC. I'm specializing in infrastructure. I'm a geotechnical engineer. And I was also road designer before being in Autodesk. And I have also a blog called Civil Made in France.
STEPHANE BLAMAIN: In French.
VINCENT FREDON: And it's in French, yes.
STEPHANE BLAMAIN: So, my name is Stephane Balmain, as you can read. I'm a technical specialist, like Vincent. I'm a structural engineer from training and construction. And I used to work in robot company before it's Autodesk as product manager for concrete, because there was one for steel, one for concrete, one for wood. And I have a structural engineer background in SNC Lavain office in Nice. So that's why we choose Nice to build our element.
So I am based in Grenoble. And Grenoble is a city in the French Alps, near the Montagne. So it's famous for the bubble. There was the Olympic game years ago. And for real, I come from a little ski resort, [INAUDIBLE], which is one hour driving away. And I am ski instructor, because it's so cool to give a ski lesson. And of course, I like French [INAUDIBLE]. And I never cook, except this. Vincent?
VINCENT FREDON: I'm based in the AutoDesk Paris office. And we also have some ski slopes in Paris. Sometimes in winter we have snow. And perhaps you know that we are the Sacre-Coeur at Montmartre with the funicular. And you can, if you want, make ski along the funicular.
But I come from La Rochelle, which is a little town on the west coast in France. OK, thank you, Stephane. And let's go.
The starting point, this is the summary of what we will explain you this morning. The starting point is this, very poor data, just those 2D polylines on a IR image. And the result, what we want to achieve this morning is this proposition with very poor data.
What are the inputs? What do we have to achieve this proposition? We know the localization. It's near Nice on the Cote d'Azur, the south coast in France. We have some numbers provided by the owner, by the client. Here we have the area of the platform and some numbers for the hold of the building, the parkings, green space, and other areas. We also have some geotechnical data from previous campaign. And we know that we will have some difficulties with the earthworks.
What the owner provides to us then is just the localization and the main position of what he would like to have, the idea he has of the project. Then here we see the polylines on the Civil 3D with the IR image and the localization of the six boreholes we could use for our proposition.
We have the data from the boreholes. You see here two CSV files we will use in Civil 3D, the location detailed CSV, and the field geological description CSV. Then here you have the position of the six boreholes. And in this file, the detail of the different layers we will have to manage in our proposition in InfraWorks and in Civil 3D.
To begin the sketch, we will use InfraWorks, of course, and Model Builder to create the [INAUDIBLE] to work in. First to be faster and more efficient, I will create a shape file from this area. It's just a 2D polyline here in Civil 3D. To use this shape file in Model Builder, I just used the Map Export command from Civil 3D. I chose this polyline, and I can use the result, the shape file, in Model Builder in InfraWorks. Just drag and drop the result of the shape file, and automatically I am geolocalized at the right place in Model Builder.
I just have to add the name and the group for the publication. And I launch the request. Some minutes later, I have a mail telling me that it's ready to use. Come back in InfraWorks, and I have the result. It's always impressive, how it's easy and fast to get the context of the [INAUDIBLE] you need. And here it's quite impressive on the source, on the coast. It's really, really nice.
From this master I create a proposition. I never work in the master. I want to keep it. If I make mistakes, I'm able to come back to the master. I make the first proposition, and I will work on the road networks in this proposition because you know that those roads come from OpenStreetMap. Then I have to make some adaptation to get the right geometry for those roads. Then first I cut the roads to be more efficient and to avoid to manage some-- too much longer-- too much longer roads. And I will adapt also the style, because it's a very little, a very simple road here in near Nice, just two lane.
I convert this road in Component Roads. It's the more advanced kind of roads in InfraWorks. I can do a lot of manipulation from this type of roads in InfraWorks. And I adapt the geometry for each reduce, for example, to get more accurate geometry for the road, to be more precise according to the existing road.
I can also work in Profile view. I can adapt in plan and in profile. I can display the profile view in InfraWorks. It's easier to work. I can move different PVIs. I can add some. I can remove some PVIs, just the work to have the best road network near the project. OK?
Another interesting tool in InfraWorks is I'm able to add the right of ways. And I will use the right of ways to manage the interface between the project and the road to be more precise in my project. And this is the result for the context, the beginning of the proposition.
Now we can begin to work in this context another proposition. Each step I create a new proposition. I remember it's to be able to come back if I make any mistake. And first thing, I import in InfraWorks the platform I've exported in SDF file, also using the Map Export command in Civil 3D.
First step, I just drop the platform on the one because I don't know the elevation I will need for this platform. And now I would check what would be the best elevation for the platform. And in a second step, I tell the platform that the elevation, the better elevation, seems to be 289 meters. Then, OK, the platform displays at this elevation with the specific gradings. Now when we say that I can very easily, in InfraWorks, adapt the gradings, the different slopes for the earthworks.
I can display different settings for gradings here in the Settings palette in InfraWorks. I can use the existing one, the default one. And I can create also by copying my own gradings with the specific slopes and texture material for the slopes.
OK then now I can adapt more precisely the platform, the size of the platform, because I have here the right of ways of the road. Then I can adapt just using the grip, the grips of the platform, to be exactly at the limit of the right of ways of the road. OK? It's important for the project to have the exact area of the platform at the interface with the road.
Next step-- this is the next step, OK. I will, for the interface here, add some components to the road, first curb and gutter and sidewalks to be able to manage exactly the interface between the road and the platform. It's very easy to add any object, any component you want to the road here. First it was curb and gutter. Now it's the sidewalk, just on all the-- along the platform. And in the palette here, I will be able to manage the size of the sidewalk to have the exact contact between road, sidewalks, and the platform, to have something very clear here.
Next I will drag and drop the SDF file of the building to have the sketch of the building in this platform. This is one of the elements I add from the owner, from my client. It's just a basic volume on the platform. It's just dropped on the platform. I can adapt the height because I knew that it would be almost 20, 20 meters.
And I know that I will have to propose to design two access, two roads here, with a road cross-- very easy to design it always with component roads. It's better to use the components roads. You have more functionalities, more possibility with the component roads, just that. I've added curb and gutter, sidewalks. It's always the same manipulation that I don't show all the detail.
I also added a road for the access, the internal access on the platform. And I will now add some land areas, some objects as land areas, to propose to my clients the different areas on the platform to have parkings, green space, et cetera, to be the more accurate as possible from the first request of the owner. But it's also very easy to use. With the grip, you can adapt the different size.
And this is the result with some tool tips automatically displayed to know exactly what is what in the proposition. And when I click with the mouse on each area, I have the name and the surface in square meters to know exactly what is the sketch and that I want to show that it's what the owner asked me to do. OK?
I think it's still me.
STEPHANE BLAMAIN: That's you.
VINCENT FREDON: OK, but I don't remember. OK, yes, from this, I'm able, no, to manage some specific view in this context, for example, for a driver, from this side or from this side. We will look at this one. For the architect that will work in Revit on the building, he is able to know what will be the perception and what will be the exact view from a driver or any person from the model. That's really interesting because it's the really beginning of the work on this project.
In Civil 3D, I can open directly the InfraWorks model. And here I want to import the surfaces from InfraWorks in Civil 3D to work on it, because I want to give the surfaces to Stephane to work with the surface in Revit.
This is the result. You see all the triangulation, which are the different surfaces automatically created in InfraWorks. Here it's in Civil 3D. I will just turn off some surfaces to keep only the surface from the platform and the grading created in InfraWorks because I want here to do a manipulation to get only once surface, the more accurate possible to give to Stephane for the Revit context.
First I use a feature line in Civil 3D. And I draw the platform. Because, remember that this geometry has been done in InfraWorks. I need this exact geometry as a feature line. On this feature line I will add a lot of COGO points using the command of Civil 3D. The command is Measure Object. And I will put all these points in one group to create a specific surface in Civil 3D. It will be the specific surface for the platform.
I do this to have a more accurate final surface for Revit. The goal here is to have-- I add a lot of points to have a lot of triangles. More I have triangles in Civil 3D, more the surface will be accurate in Revit. OK?
STEPHANE BLAMAIN: Because Revit don't load the triangles. It will load the nodes and recreate the triangles.
VINCENT FREDON: So here I've created a new surface in Civil 3D called Platform. And I add this first the feature line in the definition of the platform and the group of points. And then I have a lot of triangles as the definition of this surface.
Now come back in InfraWorks, in a new model in InfraWorks. This models is just on any surface aggregation. Here you have the wizard. Those surfaces in InfraWorks, the wizard is only one surface. It's automatic. You don't have to do anything. And you have exactly all the triangles you have created in Civil 3D, and everything is aggregated. OK?
Come back in Civil 3D in a new drawing, and I input the result of the last InfraWorks model. And this is my wizard here. I just have only one surface. It's the ground surface from the model I created in InfraWorks just for the aggregation. And I'm able to export as AutoCAD 5 to get 3D faces to give this file to Stephane to work in Revit. OK?
STEPHANE BLAMAIN: Show AutoCAD. So now, of course, when you start in Revit, you start with your own templates. And I will load this AutoCAD file, coming from Civil, but which is AutoCAD, in Revit. So here I will rename to 00, the level at 0, because it will explain how Revit works in fact. Because when you load the DWG, since you come from AutoCAD it's [INAUDIBLE]. So the bridge is there, and I have a nice object. It's there. But, in fact, it comes according to a level. And if you move the level, the object will move.
So here it's according to zero. And after I will load the coordinates of this element, when they load this I load center to center, to work in the middle of Revit. And you see, I'm in Nice with the correct value. OK?
And after, I will recreate the topo according to what Vincent have done. I just select the DWG and say OK. And you will see, it creates nodes. OK? And after you recalculate the triangulation. And here it's not-- the slope are not too high. It's fine. But the limit between Revit and Civil, we saw during our little test, are not the same. And at the end we will see, since we will create a wall, it was not the same. So we reduce a little bit.
After, I will manage to have something with a better view of the lines, the elevation. I create the level I needed. And after, I will link my 2D DWG to this level because it's not as a good Z value So here. And when I've done this, I will define the north project, because obviously, it will be this line. And you have to do it now because in Revit it moves all. And if you create something, after you can have some problems. Here you have no problems. But if you try some one ways, you could have problems.
So when you've done this, I will save this as my topo terrain. OK, and when I've done this-- so I publish, I save all of what I've done. And I will be able to load a building too. So the building, that will come from InfraWorks. OK? So I will select the same zoning. And I will export to FBX. And after all this FBX, I will load them in Navisworks to create Navisworks file. And after, I will load the Navisworks file in Revit.
Here you have to select 00 because you want to be in GIS. And if you let this, it will create this as a local 00. And so it's no more on your GIS. And after I load to create my NWC file, or NWD, like you want. And after, you can here load your coordinates with short coordinates. OK?
So you can take your building in NWC. So you have all the building around. And where you start to do some works in InfraWorks, we could have done less and start here. It was a choice, but we start to do a little bit more in InfraWorks. OK.
So after this, to tell the truth, I start, I've done the same sketch as Vincent. And after some of my colleagues, which is architects-- I know it's not all architectural work. So I try to do my best to do something not so straight. And after you have the real building, which is more classic. But we will see on the workflow.
So here, if you want to do this, the best is to create a conceptual mass element. And so you will be able to sketch the volume. So you will work on this volume. And you can put a line, a node, or what you want. After you've done that, you can load it.
Here, to be more accurate, I load the DWG in the mass element. So it was easy to coordinate to. OK, so here, after I align, and when I've done this, of course, I need to display the mass object. And after, I will create all the levels to have-- [INAUDIBLE]-- to have all the surface. Because now I have the volume, I create my level according to this building. And after I split this mass according to-- what it this? And I have this. And here I can check if it's correct according to what I want to do.
So looking this building was not so fun. So I edit a little bit. And it was odd for me because I do something which is quite strange. But at the end, I have some idea, and I want to create the faces to look at the sea. OK? And so I create two nodes and to have balcony from two sides. OK? And of course, as you know, since in Revit all is like dynamic, after I will load back, and it will create and update all the volume of the soil in my project. Here, I can check.
So at every stage, and depending of what you want, what challenge you're facing, maybe you will start more with this or more with Vincent and load after this. It's up to you. Now after, sometimes I will draw a little file about what I've done, OK, but without GIS in 00. And I just want to show you.
I'm sure you know how to load the correct value of the real building in my old project. So I have to open the topo project and load the building in center to center. OK? So it will arrive in the center. And after, I will say, OK I want here. I can move a little bit around my project to see what is the best option, so a classic. So we don't split any manipulation for two things, so you can follow when you look back. And I can speak on it. OK?
And after I rotate, and once I will do that, I will publish in this building file the correct GIS-- geo reference points. OK? Here and here, I will go to publish. Oh, yeah, not, because 00, of course, it's zero in level. So I moved to the correct level too. OK?
And you can't remove the zero because all [INAUDIBLE] according to the zero. And after I save. OK? And here, I will publish. I'm sure you all know this kind of manipulation, but it's just to be sure.
VINCENT FREDON: It's up to me. Thank you, Stephane. Now, the next step is the context consolidation. We come back to InfraWorks and, once again, a new proposition-- each time, the same. And first thing, I want to import the Revit with the result in InfraWorks. And here, the manipulation, for this manipulation I have to manually enter the coordinate of the base point from Revit, x, y, z, and rotation, to be sure to have the building at the right place in the InfraWorks model. It's really important because here the architect has work on the best position of the building on the platform. OK?
STEPHANE BLAMAIN: I create this file in Revit, in fact. It's a zero internal of Revit.
VINCENT FREDON: Then after checking the predisposition, I see here the detailed building at this right place. Then I can delete the sketch, the basing volume I did previously in InfraWorks. This is the final building in its context. Then I can easily adapt that all the areas around the building, very easy just to move the different grips and to check all the surfaces of each area.
And now I can go on with the specific views. I can add from the balcony, for example, in this building. And to see how can I see the sea, and the roads, and what I will see from the building. And here, very interesting checking here is the security for with the road cross. I can see that there's initial with a part of the gradings. There's not enough visibility to have a secure circulation and secure access on the platform, just by adding a model of cars in InfraWorks and to be as if I was a driver, and to look right, look left, what I will see in the building, in the model.
OK, then I know I have to adapt something to get a better security in InfraWorks. Then this is the crossroads I will have to secure. Then I will adapt the grading here. Then I select the grip of the platform. And I can add some vertex. And I can move them to have a different geometry of the gradings. It's very easy, very graphic to do. And automatically I have the new gradings in InfraWorks. OK, I can add all the vertex I need to be accurate along the road.
I previously had add a very high slope for the grading in InfraWorks. Here, this is the result in InfraWorks after adding sidewalks, gutter, et cetera. And here I can check with the different viewpoints what I will see with these new gradings in InfraWorks from the balcony, OK. But it's not the most important here. What I want to check is the security view, yes, this one, for a driver coming to the crossroad. And here I have the good visibility. I can see the car waiting to go and to engage in the road here. OK, so it looks-- it seems to be the good proposition to have the security, a good security here for this crossroad.
I can check all the crossroads, right, left. This is the most important here. I can see all the cars on the roads at each position. OK?
Now, I know that I have to do some optimization of the gradings because I have specific [INAUDIBLE] geological context here. I know that I have two different materials from the geological campaign. I have clayey marls. And it's wrong materials. I know that I have to propose a retaining wall. And we have this idea to create sprayed concrete and ground anchors for this material. It's the first, a the base, at the platform. It will be clayey marls. And the layer above the clayey marls is limestone. And it's possible to do a grading at one to one. It will be OK for this proposition.
Then for this geotechnical work, it's in Civil 3D using the Geotechnical module in Civil 3D. Then it's the classic manipulation. I import the two CSV file we saw at the beginning, with the localization of the boreholes and all the details of the layers in the boreholes. You can see the results. You see the six boreholes modelized in 3D objects in Civil 3D. And I ask to the Geological module to create the different geological layers I need to work on this project.
You see here? It's a very big triangles, not very accurate according to the surface, to the ground, in my project. I can adapt this with a very simple workflow. I need the rear ground surface. I can import it from InfraWorks. But you see, there's a big difference between the size of the triangles angles after the workflow.
I don't show the detailed workflow here. You can contact me. I will send you the different manipulations. It's quite easy. You are able to use all the different layers of the boreholes. But to shape the different geological layers to the existing ground surface, it's really interesting workflow. I could explain you. I could show you. I can send you the details.
After the creation of the different layers, it's easy to create 3D solids using two surface in Civil 3D. And these 3D solids can be important in InfraWorks to have a good visualization of the geological context in InfraWorks. I see the boreholes. This layer, this is limestone. This is the limestone layer.
And now I want, in Civil 3D, to create the details, gradings I want for this project. This is in green, the shape of the platform and the gradings. And in red is the limit between limestone and clayey marls I want to use for the detailed gradings.
I turn off the surface I don't need for this manipulation. And the beginning is, once again, to create a feature line on here, on the platform, because I remind you that I've, in InfraWorks, I modified the size of the platform to have the better visibility for the security. Then I recreate, with a feature line, the exact platform from InfraWorks from this feature line. It's easy to do just to pick the different triangles in Civil 3D.
From this feature line, I create a first grading with a high slope because it will be the base of the grading. And we will have sprayed concrete here. Then it's almost vertical, not exactly but almost vertical, not with too much high slope because we have difficulties with Revit. Revit is not able to create vertical triangles. This is the result of my first grading using the limit with clayey marls and limestone.
OK, first step-- but I need to have a more simple line here. I can create sprayed concrete with this shape here. Then I will use this first grading to create a second feature line here, just clicking the different points on this grading.
I want to have something more simple. I do all the all around the-- I do it. I do the feature line all around the platform. And I delete this first grading. I don't need it anymore. It was just to be able to construct the second feature line. OK?
Now I have just, in my Civil 3D drawing, two feature lines. And with those two feature lines, I'm able to create the final grading, detail grading I need in Civil 3D. And I will impart after in InfraWorks.
Here, from this feature line, it will be above this feature line, it will be the limestone. It's the grading with the slope one to one. It's very easy to do in InfraWorks. The target is the ground, the existing ground. And for other part of the grading, it just fill in with inside the feature line, very simple to do with Civil 3D. Just click inside the feature line, and you have your final grading. OK? Here I've displayed in red the limit between the two geological materials. OK?
Always the same manipulation, to have something better for Revit, I add a lot of points on the feature lines for the platform to have a lot of triangles, little triangles. It will be easier for Revit to create its own surface.
Before going in Revit, I can add this detailed grading, final gradings, in InfraWorks. OK? For the moment here, I have a simple grading in InfraWorks. But I just drag and drop the Civil 3D file in the sources in InfraWorks.
And after some settings, I delete the surface I don't need to keep just the finer gradings. This is the result here without any texture. It's just the InfraWorks grounds. And I'm also able to add the specific texture to have a better view of the result here. It's always the manipulation Map Export to create the SDF, et cetera. And here, with grass texture, here, I see better the result. It's exactly the Civil 3D grading in InfraWorks, in the context of InfraWorks.
I think it's to you.
STEPHANE BLAMAIN: Yeah, I think it's to me. So now of course, I will have this in Revit. So to have in Revit, I will link this new pure AutoCad file, so by [INAUDIBLE] date, of course. And I open. I will change this surface. I won't create a [INAUDIBLE] because I have all the results I need in [INAUDIBLE], much more accurate than doing it in Revit. So I delete the note where no more accurate, like this. It's where it's green, OK. Because if you keep it after-- that's not correct. So I delete all of this.
You see the new DWG here. And after, I will select from this DWG, and it will create the new point. OK? So here it's-- in fact, it's only this one, but it was working. And here you see, I have all the detail. And we have done, I think, three or four tests, because we used to have something really strange here because [INAUDIBLE] twice. It was correct in Civil, but not in Revit.
And so here, from the line, I will create a wall to the-- [INAUDIBLE] to the top wall and bottom wall. To tell the truth, at first I want to the sprayed concrete to the top because I will have a constant layer of anchor. And with the variation, I have to move from two to one. So I'm not sure it's really optimum in calculation and what's needed. But I'm not sure it's optimum in the [INAUDIBLE]. But we will see after.
So here I have to display the triangles to have this line. OK? Because it's the triangles between the top of the wall and the bottom who gives this. If you display only the classical line of the terrain, you won't have it. OK, and after, of course, I check. And since I have a line after, I can do what you can do to create a wall, and same for the other side. OK?
And of course, you have to cut and to look the other way to see where we are. So here you see, here we'll have-- no, you will have less anchors [INAUDIBLE] to the top. Here it's different because it's really high. So of course, we want to create something like this. And of course, when we do this, moreover, it's important to review, so here. And it's easy to select the right [INAUDIBLE] classic. OK?
So here I create all the wall. And when you create this in Revit, you create two things. You create the volumic object, that you can see. And you create the analytical element too. And of course, I don't [INAUDIBLE] of the building because it's not so much [INAUDIBLE]. Here I have the analytical element of the wall. And of course, I will now do the calculation of this sprayed concrete with the anchor in Robot.
So I sent Robot. So of course, here it's easy. It's very simple because there is only one wall. But you have the properties of every wall. And you can align independently the analytical element from the [INAUDIBLE] element on the axes, or reference line, or plan to have more accurate file. OK?
And after, I will need to put all the loads in it here. So here, since after it's not applied, I have some coefficient here. That's why it's up here on there is some load at the top. Of course, you can change the local or z-value you have the load in the correct view and the correct direction.
And after here, you will produce the load on the part. So here, of course, I will choose three points, and I will choose the value of the pressure on three points. And I have a linear regression between these three points. OK? [INAUDIBLE].
So when I've done this, I don't know the space value, so I create a [INAUDIBLE] in Robot directly. But to tell the truth, it will be more accurate to create in Revit because it will be more polymetric because here you [INAUDIBLE]. It's five minutes, but is it better to have 3 meters or 4 meters and not the same size of sprayed concrete?
Of course, in Revit you can modify easily. Here it's a classic [INAUDIBLE] of the element. So here it's the ebb and here the tube. OK?
So I think now I would have done this in Revit with some parameters, so it means I will create more roundtrip between Revit and Robot. And changing the parameter in Revit send back to Robot instead of doing that. But in fact, I think I've done this at first because since there is a big slope here, the pressure is I. So I don't know if it was 3 meters or four meters, So I started in this.
So here, after here you have the terrain. So I don't need to have all this. So you can adapt by selecting and changing the value of the nodes here. And of course, here I can create some axes and move the axes. It's same, same timing. And here it's-- because at one time, I want to do them not always on [INAUDIBLE], but with some inclination. But it was not accurate.
So here we'll put support at the bottom, because as we spray concrete we will create support here. So I select all the nodes. And after, on the same, I will create support here and on the other way. And I create a beam at the top and at the bottom, a beam, but in the [INAUDIBLE]. We can see. After I choose the mesh, and I do the analysis. So first I will look at the deflection to see if it's too much or not.
Here I don't have all the building on top. But if I have I would do it a little, but much harder. Here, I have no problem here because I put a lot and I don't see here. So here we'll do some more on [INAUDIBLE], so Classic select, and after Copy, Paste in the elements.
So, I could have clicked graphically, but in fact, I don't create enough axes. So I put the value and copy. OK? And of course, I do the calculation again. Here, I want to have one here. So I copy two. And I don't trade the classic combination because they are already done in Revit, so classic [? SLS, ?] [? ULS. ?] And here since in [INAUDIBLE]. There is no seismic or wind. It's fine with the free or a classic combination. OK?
And here I have the result. Of course, I can always adapt, here we don't see exactly because here you have some lines. And after, I need only two lines. So at one time, I have to move from three lines to two lines. So if the height was the same, maybe it will be other. Because I need to have, really at the top, this because, since there is a lot of pressure at the top, I need this. And after, I will do the calculation of the concrete, sprayed concrete itself.
I'm doing it according to US rule. OK, so here I check all the values, apply it to the element. And after I do the calculation of this shell according to analytical element. And after I display the value. So here we could have an optimization between the size of the sprayed concrete, so distance between anchor and the global displacement and local displacement.
And once I've done these ones too, I can update, of course, in Revit, the element. So it will update according to the analytical element, because I created analytical elements. So it will be in the middle, the physical elements. So if I show you in here, you have. OK?
So I think for this kind it's fine. If I have done some beam or current change in the building, sometimes you have to take care because you will have, if it's a new beam, it will create from the new line in Robot back to Revit. And if it's an existing beam, it's where you have created the beam, of course the beam will change.
But, for example, if, I don't know, we have a beam there and a wall there, you won't keep the center line because sometimes the wall is in 20 and the beam in 20. If you adapt the size of the beam, after you will put in the wall to facilitate the [INAUDIBLE]. So your can update like this, so sometimes it's cool because there is no other constraint. But sometimes, it better to say, yes, this beam is not so accurate. What do we do? And you can adapt and have to move a little bit from a drawing point of view and [INAUDIBLE] point of view. [SPEAKING FRENCH]
VINCENT FREDON: Thank you, Stephane Oh, you can click-- OK. This is the final result, importing in InfraWorks in a new proposition, again, the results, all the stuff done by Stephane. Then we can use the visualization, all the tools for the communication in InfraWorks, using the alignments of walls or creating a orbit view to see, to check everything in the model. Then you see all the angles here and the sprayed concrete as a retaining system.
And to check and to show to the client, to the customer, you can come back to specific views to show the security, to show that the perception of the building in this context, everything, that it would be impossible to do with a classical approach only in Civil 3D or Revit, for example.
[INTERPOSING VOICES]
--only, of course. This is why InfraWorks is really powerful to do this. When you can be wherever you want on the platform to see exactly the proposition with all the parking areas, the green space. You can add, of course, any 2D models from the InfraWorks libraries for vegetation, cars, any people, what you want, to be more realistic when you do the presentation of the results of your proposition. OK?
STEPHANE BLAMAIN: And with this kind of thing, since you will spend less money in the earthworks and the sprayed concrete, you can have more money for the building and more for architecture. That's a true structural engineer who tells that, because usually the global price of this project is really depending on the earthworks and of technology to maintain all the elements and how we will create it because you see, here I have three lines. After I have two lines. Maybe we will see with the final. but it will be easier to have a constant and to have always the same. Because when you have to create this, you won't do like we have done. You won't do by [? fuzzies. ?] OK? And sometimes it's easier to have only one line and have another line, even you spend a little more reinforced concrete.
VINCENT FREDON: OK, thank you, Stephane.
