Best all round CAD I
I have been using VW for many years and though I have spent months using and trying to love software like Rhino and Solidworks, I have gone back to Vectorworks for 3D mechanical design.
There are a few reasons for this. The first is speed. VW is much faster at basic design but most importantly, it is much much faster to change and edit models than either Rhino (impossible) and Solidworks (difficult). When I was using SW, I found that at some point, models would become impossible to edit and you had to go back to an earlier version and start again. VW always allows you to edit right back to the fundamental components. Yes, with bevels and radiussed edges, you have to ungroup and recreate the edge on the way out but it's no big deal.
WW is not perfect and there are a few things in SW that I would like to see in VW but overall, VW wins by a big margin for real work. VW occasionally bombs but less than SW. Yes, the manuals could use some work and some bugs have not been fixed for years and years but overall, Vectorworks offers more power, ease of use and speed than anything else I have tried for a fraction of the cost, so I am well prepared to forgive the few drawbacks.
