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.

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

nm, figured it out with an invisible triangle lol

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

<r>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.<br/>

Yes, I got ...

Nope. It was something even more silly than that. When I set the floor height for new floors in prefs, it somehow thought I meant 10'6". I've noticed sometimes when you type in a number it second-guesses you and changes the input to something odd.

<t>I created a rectangular first level with 9'6" walls. Most of the perimeter of this level is intended to be earth-sheltered.<br/>

I created a rectangular second level with 2' 4-1/2" walls. In 3D view, they look taller than the 9'6" walls.<br/>

Note the slanted walls in the front of the ...
