complex wall shape

[codevark]

I'm imagining a roughly tetrahedronal structure. Each side is a right triangle with the lower corners cut off, leaning at a 45 degree angle to meet the edges of the other sides. Each side also has a roughly semicircular hole in it, which would line up with the second floor.

Yes, I got this idea from looking at a plastic shipping brace that came in my air conditioner packaging.

Is there a way to slope the bottom of a wall? If so, I can make a four-sectioned wall with slants, export as furniture, and rotate it appropriately.

Otherwise, I have no idea how to do this.

Why would you want to slope the bottom of the wall if you are going to export for furniture anyway? Just slope the top, export, import, and turn it up-side-down!

If you want a tetrahedron you could create that with the Generate 3D Shape tool (tools menu). And there is the geometric forms library from OK Hoff: https://sourceforge.net/p/sweethome3d/d-models/299/

Good luck!

I forgot: there's a new relatively new function under the tools menu: Generate Basic Shape. Guess what? It also generates a tetrahedron!

nm, figured it out with an invisible triangle lol

speaking of grids, a hexgrid would be nice for things like this.

[codevark]

the three triangles (missing the lower corners) will comprise the roof. can you generate a tetra and put windows in it?

[codevark]

I'll have to accurately measure my physical model and scale it. the angles are 45, but with the side lengths I'm using, the edges don't match up correctly.

Nope, you can only create holes in walls and floors. In walls you can use any object imported as "Door or window" and to create a hole in a floor you use a staircase. Export the wall or floor without selecting the object that creates the hole and the hole itself will be retained in the export.
You can of course combine multiple geometric forms 'around' a hole and combine them for export.
