Hi Nate!
I recall Martin saying years ago that A:M wasn't built to be a CAD modeler and it wasn't a niche they intended to pursue. You've been warned!
None-the-less A:M does have strong OBJ and STL exporters and a number of A:M users are using A:M to create objects for 3D printing*.
True modeling Booleans for Splines is a big leap. If you need it, I suggest modeling in A:M as if you were going to use its render Booleans, export the base model and the "cutter" as separate OBJs, then import both into one of those programs that people use to fix polygon models for 3D printing and do the Boolean cut in that.
*Our Image Contest Medal is modeled in A:M, 3D printed in resin, then the resin print is used to cast medals in pewter...
