I have a dozen 3D modelers, some now defunct products,  in hopes someday of making my own props.   I have been able to make stuff with Boolean operations in TrueSpace, but it's most recent updates have virtually made that operation no longer possible.   I have tried Hexagon, and Shade, and the menus are too abstruse for the digitally challenged.

What is the simplest one around?  If I could import stuff into an app and do Boolean operations,  I would be happy.
