The Question was...

How do I make a Solid.....

__Yes Solid...__. Tetrahedron in Revit...?
What is a Tetrahedron?

It's the simplest solid with the least amount of sides (like a pyramid in Egypt)

So.

My first reaction was "just" create it in the massing or adaptive component family editor... simple right?

Wrong.

Wrong.

It turns out it is not possible to create a Solid Terahedron in Revit using any family editor. Why? Because a Solid Tetrahedron requires 4 triangular faces and one rectangular face. You could read more about it here.

So then I thought the best way to do this is to use Dynamo and bring the Dynamo geometry back into Revit. So below is an example on how to create a simple Tetrahedron or pyramid that is 1 unit x 1 unit x 1 unit.

Once you have mastered this concept you could apply this to any sided solid. Good luck polyhedron building and dont forget Dynamo is always Revit's "wingman".

Sorry to be pedantic Marcello, but that's not a tetrahedron. A tetrahedron is a regular 4 sided solid. 4 triangles only, no square face, i.e. a triangular pyramid. I'm sure you can make one of those also :)

I know this is a dynamo blog... but you can also do this via formit 360...

Great stuff, this blog is a gold mine, and thank you for sharing.

I would like to contribute by showing how you can make such a form i native Revit family editor with this short screencast:
