Thanks to Rich and Lazyman. After working my way through the stuff that doesn’t work, OnShape has come through. It has the same kind of command structure as Alibre but differs in that it works. 😉
It feels to me like the difference between these two and SU is that they seem more right brain and SU seems more left brain. That’s a good thing for me.
Anyway I can now draw cabriole legs in about five minutes and go back and tweak until I’m happy.
…. and it’s FREE!
Thanks guys!
