I am AutoCAD trained and find it bulky, overpriced and far from intuitive. Who needs 6 ways to draw a line?
3D modelling is cumbersome and to get any rendering performance/shaders/textures/ray tracing you have to buy this and buy that, video cards yadda yadda. To this day, I have NO idea where the hell the reputation came from.I use Vectorworks. (aka MiniCAD...Mini as in "smaller than a MainFrame") Available for PC or Mac, it exports/imports in all the important file formats like .dwg, .dxf. Full blown 3D, NURBS, the works.
