From the shapes you are showing there it should work. In Carrara select all your paths and un-group, then combine as compound.

Brian this is one of the rare times when the spline modeler can get you some pretty complex shapes without too much work - if you already have your paths set up in Illy or Draw.
Sort of like nurbs modeling in MOI or Rhino, but you can push it to far and Carrara will choke.
