  • Perpendicularity of a Cylinder

    I am trying to measure perpendicularity of a cylinder to a plane. The physical plane surface is directly perpendicular to the cylinder axis. The issue is my result is always zero. Also tried it as a constructed line using the cylinder and same result. The workplane is correct (-X)....cylinder axis is parallel to Z.

    What is your displayprecision value set to? Maybe increase it?
    Post code of your features and dimension output, so we can see what you are.

      Resolution is 4 places in mm

    Always pick your datum 2nd. So if the cylinder is the datum you would tolerance the plane to the datum in legacy. in xact you would define the datum cylinder and then only select the plane then the datum in the control frame.

      I posted the perp window.

    Looks like you haven't run CYL_B yet. Datum A has been run, maybe run the whole thing?

      But the A datum is not perfect, so there should still be a perp result with a nominal CYL_B?

      Yeah, AndersI but if he or she didn't run CYL_B, then most likely didn't run the feature callout either, I have notice when using Xact, even if you run the features, if you don't run the callout, it doesn't change either, that's why I'll highlight the 2 features and the callout and Execute Block.

      Not if he levels to A datum and and doesn't measure CYL_B... It will still show perfect

    I agree with KIRBSTER269 Are you running marked sets? If so, make sure the cylinder is marked for execution.
