But if it works for you that's great. I looked at a number of programs but the only one that fits my understanding is Wings 3D.

You essentially use difference to subtract the edges:

There are also libraries that let you create these sorts of complicated shapes much more easily, but the one I tried for triangles used deprecated commands, so it was outdated.
Not one to give up easily, I sat down last night at work and went through the polyhedron section of the user manual. In doing so, I learned how to create pretty much any shape I want. It's complicated, but very precise. You have to divide up any shape you want to create into a series of faces (the surfaces of the shape), then divide those faces into triangles that are delineated by the corner points. So for instance, the front face of a cube would be denoted by two triangles to make a square. Once you create the shape in the size you want, you can translate and rotate it into position.
That Wings 3D looks good... if only I had even an iota of artistic ability. My clockwork brain thinks in code, not artistically.
