Re: Double-Dimensioning

Good comments below. Of those on the list that are involved with CAD drawing production to some extent (which is likely almost all of us), which software are you using? Are you doing 3D modelling with automatically-generated iso's and paperspace-style G.A.'s?

It might be interesting to see what others are using to get the job done and your thoughts on the pros and cons of different packages.
