I started with AutoCAD for DOS back in '89 and have used it since then through all the versions. I must admit that I like SolidWorks better than ACADs 3D.
When I acquired this MAC (PD went TU) everyone assured me that Turbo was great. But I found that the Mac version was missing many very useful features and tools that were present on ACAD as well as being quite buggy.
This was 2012.
Downloaded the QCAD last night. Haven't done anything with it but looking through the menus and tools it seems to have good potential.
