Great Post J.

I know that I am probably more guilty than many of missing lots of these standard practices. Having come up through the ranks as a hobbyist, I never learned the industry standard. Combine that with the fact that most of us on this list are the end consumers of our drawing and models, we tend to not put in many of the details you mentioned as we know what we mean. Not that it is right, but we either don't know better or feel the extra time is not worth it.

Very glad to have a real professional on the list helping us understand what the target should be.

You bring up a great subject on the tolerances. Not just from the convention that the number of places after the decimal it telling tolerance info unless you say otherwise, but even the fact that in industry a good part is based on the tolerance. May hobbyist think that they should alway try to hit the exact dimension.
