ConceptDraw Community

I currently am using Visio, however, am considering moving over to ConceptDraw as I am looking at buying a MacBook Pro and would rather not run a PC emulator.

The commands that I use the most in Visio are the Shape Operations (Union, Combine, Fragment, Intersect, Subtract).

ConceptDraw doesn't seem to support these to the same extent (especially Union and Fragment).

Am I missing something?

Thanks!
