I am a new user of Vectorworks but have found the transition pretty easy. We do mainly 2D structural engineering drawings and have found it very fast. The learning curve is not as steep as other software.
I originally trained on Microstation then migrated to Autocad. When I set up myown practice I purchased Turbocad because I just couldnt afford AC or Microstation. TC, however, just doesnt cut it at the professional level. Having worked with Architects who used Minicad (earlier version Vectorworks) I was always impressed with the quality of the drawings, the results just seem to look so much better than AC.
After much testing of different packages I chose Vectorworks (a few months ago now) and have never looked back. AC and TC just seem so primitive when compared to VW.
Just my experience that I hope helps.
