Re: Modeling best practices tutorial

Chris, thanks for your comments. I agree maybe the wording is negative at first. For the floor datum plane, it is used because the floor can be offset to position the model in the z-direction, with a single parameter.

Hello all. I'm trying to offset two cylinders at a fixed radius from one-another, without an enclosing surface. For example, if you had shafts that were supposed to be 8 inches apart, from center to center, in an assembly. Or if you wanted to set the distance between gear centers and have it be vari...
