How to create Triangular prism geometry

Hi

 

Im trying to create a very simple 'loft' between a line and rectangle in a curtain wall panel family (like how it is captured in photo using adaptive components). I was struggling to create it in REVIT.

 

Any ideas?

 

Many thanks

Draw 4 triangular flat surfaces, all with a common vertex at the center point of the panel. Then, elevate that center point.

Thank you Alfredo but I dont think that's achievable through a curtain wall panel family or any other family types, other than MASS family or Generic Model Adaptive. Any other ways you know of?

Sorry, in my previous post I was thinking of a pyramid with one apex point. That won't work for what you need to do.

Now I realize that you want do this in a curtain panel family. Do you mean a regular curtain panel family or a pattern-based curtain panel family?

I think there are several ways to do it....

If you use Curtain Panel Pattern Based , then a way can be that shown in my screencast:

  • Do all the sides have a slope (it's hard to tell by the image).
  • Does this need to be a generic curtain wall panel family? (not pattern-based)

If you need this to be a generic curtain wall panel family, it is possible. You need 3 solids by sweep, joined (parts A, B, C in this illustration).

This has some difficulty because you need to constrain the path of the sweeps so that the shape keeps its integrity with any size of panel in the project. But it is possible. This will work for any rectangular curtain wall elevation, not for irregular shapes of panels.

If you use a Curtain Wall Panel family you can do it also in several ways beside that mentioned by Alfredo:

  • a way could be using Reference Lines as guide and parametric Extrusion - Solid + Void

An easy method could be to make a Curtain Wall Panel using: Create > Forms > Blend.

The condition is to accept a chamfer of minimum 0.8 mm.

In practice this is entirely acceptable , but it's up to you to do it or not....

Thank you guys,

 

These are great solutions. I did the chamfer for now since the triangular prism was the void I was trying to achieve in order to cut another geometry. The geometry is angled at all different sides, it would be too much effort to constrain it and may not be even possible. It's really frustration such a easy geometry is not achievable using the most generic models.

Maybe you should post a picture of what the overall thing you want to achieve instead of asking how to do this one piece so that we understand the context and may come up with a broader solution.

"Not even possible"? The previous posts show some 3 ways to do it. It is possible, and it can be done in a few minutes.
