  • Actuals not matching

    This is my first time posting and I appreciate any help you can give me.

    When I construct a circle out of points that have been created with peirce points, the point actual that is used (PNT47's polar value .6994) does not represent the actual on the constructed circle (CIR25 1.4178 diameter). Should be .7089 polar radius. All the points used show a much smaller actual polar radius then what PCDIMIS used to construct the circle. The constructed circle happens to give me a good diameter but I can not prove it using the points because of the difference in the actuals.

    Are you using CAD data or programming on the part itself?

      It has to do with how you are constructing the circle. Read this and ask more questions??
