Trapezoidal wall cladding

[stuart_willows]

We are trying to produce a model of an industrial building complete with trapezoiodal profile wall cladding and roof sheeting. I have tried to get something from Kingspan but it;s not usable as you can't attached their parts to a sloping roof (!!) and the sheets on the NBS BIM Library are not profiled, even though the adjacent picture shows that they are!

Does anyone have any prfile cladding sheets that I could use or pointy me in the direction of one. TIA.

I've had success creating a curtain panel to represent once cycle of a repeating wall/roof sheet.

Some notes:

1. In this case, it was a typical 'R' panel sheet. I made a 1' wide representation of it as a curtain panel. I went back and got rid of the smaller ribs because they just made 1/4" scale elevation views (or smaller) look black.

2. I assigned this panel to a curtain wall placed outside of, and in addition to, a structural wall. This curtain wall was set to have no mullions and have a vertical layout.

3. Since I made it 1' wide, the wall you want to sheet had better be an even incriment of 1', or else you're going to have a sheet hanging out past the corner that you're going to have to use a void to trim.

4. On a larger building you'll soon discover that such a curtain wall has an upper limit on the number of vertical grids it can support before failling. The limit is smaller than you would think. You'll end up using many curtain walls, and performance will suffer.

5. It's a pain in the neck.

There are other methods. You could make voids that cut the appropriate pattern into walls and roofs. You could use adaptive components on a patterned mass.

Unless you absolutely NEED such an accurate model, I'm going to strongly recommend the following:

1. Don't even attempt it.

2. Just use a model pattern to surface normal walls and roofs so that elevations and roof plans look approximately right.

3. Cut your sections and details where necessary and use a 2D profile drawn as a detail item to represent your sheet where it's needed.

Thanks for the response. Not quite what I was expecting but no worries. I can't believe that it should be that difficult to get this working properley!

I was led to believe that the reason for using Revit was to do things correctly, so that they looked right. A picture of a cladded wall is not a cladded wall and will nerver look right when renderd. Trapezoidal sheets cast different shadows depening ion time of day, orientation, etc.

Sure.

I wish Revit would allow VERTICAL sweeps/voids, along with a spacing parameter, in wall structures (and roofs). Furthermore, I wish they would allow it on a subsurface layer (such as insulation) and then the surface layer would follow the profile too. This would be an easy way to get the insulated metal panel that you're looking for.

But it doesn't, so I answered as best as I can.

If you do want to pursue the curtain wall method, you start by makeing a curtain panel family with an extrusion to represent one cycle of your panel. Here is my simple R-panel.

I’ve struck the same problem numerous times. I’ve tried a few approaches, none of them are a good solution. Autodesk really need to provide a solution to this.

1. Create a wall the thickness of the core panel, then create a face based family for the ribs. 

2. Create a wall the thickness of the core panel, then create a custom beam family and use beam system to array the ribs/beams at the necessary centres. 

3. Model in place a kingspan panel and copy paste using masses to trim out openings.

I also want to model the trapezoidal sheet metal facade in a vertical grid in Revit and fix the facade to a roof with slope. I tried different ways but at the end there are problems with openings.

Has anyone solved a solution for this?
