Solidworks and Autocad have horrible backends. They are slow as sin and single threaded. Neither company is paying technical staff to improve the product. I use openSCAD for 3D printing, but its limitations become quickly obvious. All surfaces are a series of 4 sided polygons. I would prefer to be able to define smooth curves and only choose the resolution on export. The language itself is a trip to wrap your head around. I regularly need to keep 4 levels of transformation in my head when working on an individual piece. There are better ways. I will need to look at AngelCAD.
