Hello,
A real thank you for the tutorial.

Thank you for the simplicity on that, as sometimes are the basis that haunt us the most.
As for what you call a "max is not a production software", what would you call one for that, Rhino?
I am starting to work with a machine that prints .STL files, our method is to used autocad and maybe 3ds max, but it will be autocad, what is your tought on this?
Best regards and thank you once more:
Matias
