Although I am a sporadic Blender user, mostly has a hobby of for personal freelance work, I use 3DsMax much more often, because that's what we (are forced to) use at work.
I am an architect however, so my background and first contact with CAD and 3D modeling actually came from AutoCAD, so I am quite accustomed to Boolean operations and Solid modeling, my ascension to full NURBS should be a bit easier eheh.

I actually have more difficulties in getting into full Mesh modeling and Blender in general, because in 3Dsmax I use almost exclusively curve based modeling (with extrude/sweep and other modifiers) all the time, and I've had a bad time doing that in Blender because it's curve editing tools are quite messy and even worse than those of 3DSmax

Thanks for the tips though, I'll be sure to take a look at those threads, a reminder is always helpful. :)
