Profile a radius using autocircle

[rebeldude]

Hi everyone,
I'm checking a radius using autocircle off of cad. It locationally dimensions fine, but it won't do a line or surface profile. Do I have to take single points only to profile this radius or is there a secret to this with PCDMIS I don't know

A circle is a single entity. You could do ROUNDNESS to see how 'bad' the surface is. IF that is not good enough, you will have to do it as points, either as a scan, or single points, make a set, and do the profile OR do single points then dimension each one using 'T'.

Are you using V4.1? XactMeasure GD&T? Do you have datums to refer to?

I found that V4.1 does not like profile tolerances without any datum references. I am not sure whether that is even correct. You can have a profile call without any datums as second line on a composite. But I am not sure that you can do that as a regular call too.

Yes you can have profiile without regard to a datum but the feature should have basic size. For example, profile of a radius. Form is a "cheater" method because it has no relationship to size. The software would have to allow bestfitting of the basic form in translation and rotation.


"Cheater" as in - not having the right tools.

I am using 3.7 MR3. I wish I could use autocircle to do this though. Hopefully in the future they will have a option to make your autocircle points single entities so that you can profile them also and dimension them locationally off of the same feature. Thanks everyone for your help.

Thanks. Learned something today...
