Construction Challange (BEVELING related)
Let's start with a Dodecahedron. Why not.
Suppose you had a simple beveled Dodecahedron (smaller than src object by the bevelling).
Take the large faces left after BEVEL ... and extrude them outwards. Call this BEVEL-AND-EXTRUDED (bae).
Now ... subtract bae object from original dodecahedron ... you should be left with the part that was originally bevelled away.
So you would be left with a ROD-BASED dodecahedron ... a wirecage with some thickness so as to be a manifold. The general cross section of a strut in the final result woudl be triangular.
Let's call the operation BEVEL-INVERSE (on solid). It is an operation of bodies in my head as opposed to edges or faces. Just the way I prefer to think of it.
I found this hard to do last night having tried it for a good while ... hard to do without BOOLEANS. Probably because I'm not being imaginative at this task.
Anyone ... wa way to get the 3D INVERSE of a bevelled Dodecahedron ? Maybe call it the "bevelled complement" ?
I have something very cool to show next after I figure out BEVELED-COMPLEMENT.
