I know, it sounds weird, but I have a print that calls for Parallelism of the Center line of the part to 2 Datums, both of which are perpendicular Cylinders on the right side of the part. What would be the best way in dimensioning it?
Construct midline from A & B cylinders & align to that. Create a line from the 5 holes. Check for perpendicularity. I believe the only way for parallelism to be checked is to project circles from A&B cylinders onto the face, construct a line between them & see if pc dmis will accept parallelism between A-B line & line that you constructed from those 5 circles. Once again brilliant engineering at work. What do they teach & how do they teach at those fancy expensive engineering schools? I've only have had problems with those newbie engineers who think they know it all; I can't count how many times I got into fights with them over their bs ideas, totally unworkable GD&T callouts & tolerances for plastics that require millions of dollars worth of super precision measuring technology.
