Cad Help please - Cut2D

[John S]

Cut2D exports to Mach fine, although I have a few cad / cam programs I use cut2D for a lot of simple stuff like panel cutouts because it's so quick.

As regards 3D programs, there isn't an easy one because it's a frame of mind and you have to see and think in 3D.
There is no proper 2D to 3D converter because how does it know the profile of the Z or vertical shape from a 2D drawing.
Most 3D programs however do work very similar to this in that you darw a shape [ 2D ] and extrude it into 3D.

Alibre has a free downlaod of a working program called Alibre Expres, the starter version is about £99 which believe me is cheap, Solid Works, the industry leader, is about £5K
