Man, that is a profound comment. I learned mechanical drafting in the "t-square and triangles" era, and have been doing 2D designs for almost forty years now. I've been using 2D CAD for about 15 years (couldn't afford Autocad), and am working to make the shift to the solid model route....but I've been doing 2D for SO LONG that I am finding it a hard slog. I use Turbocad Pro and have been for a long time. Solidworks it is not....but then it only costs about 1/4 as much (less if you buy when they are coming out with an upgrade).
I have Autocad, an old version, but I went thru these tutorial videos and Sketchup looks impressive for ease of learning.
