GD&T (again)

[[Da...]]

Ok, lets see what trouble I can get into now. Lets say I have 2 bushings with a 1.51 inch ID that are 4 inches long, and are 24 inches apart. Once a weldment in completed, I need to verify that these bushings can "pass a 1.50 shaft". What would be the best way to show this in GD&T. We have tried a couple things like coaxility of one bushing to the other, but making either bushing a datum seems to skew the measurement.

I just came across a similar situation. I used Cumulative radial runout.

I would treat it like a single cylinder, evaluating max inscribed.

Oh, and make sure you're measuring as close to both ends of each bushing as you can.

Just using a continuous feature statement should do what you are asking for.

getting the ends is the tricky part. Yeah, in this case, I am not using Calypso, and the software I am using does not take into account the 'nominal' length. At least when I have to do this in Calypso, it take the nominal length into the eval. I'll look at all options tomorrow.
