Alibre Design – a Great Parametric CAD program
I love this program! After looking at many different CAD packages I decided on Alibre Design over a year ago – the Personal Edition was $100 then, and it’s more now.
It has a very good sketch mode with parametric dimensioning that stays intimately connected to each object, and you can re-dimension at will. It was a bit of a learning curve, but there are a lot of vids that help a lot, and its well worth the time.
