  • Profile a radius using autocircle

    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.
