Profile does not take the whole curve of CAD

MihaelR
Hi, I have selected a curve to measure a 2D-profile. The strange thing is that PC-DMIS does not recognize the CAD curve entirely. It goes ok, untill one curve.. Then it goes out of screen. I understood that this is some setting you have to set in settings editor.. But which one??

Briefly, there should be some settings in settings editor which control the CAD curves and helps PC-DMIS to read these curves better. Does anyone knows more about these settings??

  • OTE=sealevel;n447989]I still get 'off the CAD' but on the amount of .0001 to .0002 when OFFline. (the 2D profile application still not acceptable to me!) Very strange. And.... that is only when using Optics. If I recreate the profile with a tip/analog scan (the same profile as Optics, it is dead-on.

    What you are seeing when using 2D profile offline is due to the following:
    the nominal form of the 2D profile is a series of line segment, not the exact curve, when you execute offline, it returns the points on the nominal form as the measured points, but the points' theo data is from cad, therefore there are some difference. Online and offline both compare to cad(theo), the difference is the measure data, it is from nominal form for offline vs from parts for online.
