Re: Free and easy to learn 3D CAD

I have used a product called ViaCAD 2D3D for several years now. It's available from http://www.punchcad.com It's priced at $100, but is frequently available with a 25% discount. There is at the moment a free trial offer available. It is relatively easy to learn. It's not as powerful as SolidWorks, b...

I would like to suggest that Viacad 2d/3d v8 is well worth a look. At just $99, and with PC and Mac versions available, it is excellent value IMHO.

The standar...

Hello Jack, I have used it for a while now, and I like it a lot, particularly for the price. It is a little quirky to use in some respects, and the manual is sometimes less than helpful. I have found the greatest benefit was in joining the related user's group, and the members there are extremely he...
