That looks good, yes. Given that EE and ME influence each other at
least until the 2nd stage, it would seem that the process should
be open until that point.

I'm just beginning to discover what exactly is involved in mechanical
design, so perhaps these are stupid questions, but are there other
tasks only a solid modeling CAD can do besides providing smoother curves
than a mesh-based system ? Also, couldn't one use, say, AoI as a solid
modeler by simply not creating meshes and working with solids instead ?

Heh, right ;-)

You mean that the implementation of "union" is defective ? Or would
that be some other function ?

Well, in the end almost everything gets rasterized ;-)
