You are so right about it not being easy to let go of the 2d thought train. I feel that I am too set in my ways to think outside of the box, and would learn 3d far quicker with some personal training, preferably face to face so that any problems can be directly explainned. That is why I would like to find some form of nightschool (at age 69) etc. If I did learn 3d I would ceratinly want to be able to put cutter paths on. I know that with my router I would only be able to contour a flat sided (base) model, but that would still be awesome.
