Hi Michael ...

Yes, ViaCad does look like a workable option.

It seems that MoI, ViaCad and possibly Draftsight would make a very inexpensive modeling and drafting combination.
Add one of the lesser expensive rendering programs and 3d PDF and one would have a pretty complete tool box.

I personally have a bunch of more expensive programs but am always on the lookout for workable solutions
for people getting started with low budgets.

And, if a few hundred dollars will produce professional results why spend thousands?

thanks for the information.
cheers,
eric
