compare a measured point to a theoretical line from CAD

BlueRay
Ok so I'm pretty new with this software, but here's what I'm trying to do:

I'm using the auto line feature to guide to a modeled center line of a hole (the hole dia is smaller than the probe I'm using).. Using the readout I can see the distance to this center line as a vector and see how far away the hole is compared to where it's modeled to be.
After seeing the hole is correct, I'd like to now take a point with the probe in the hole, and then compare that measured point to the vector of the CAD center line. Ideally, I'm looking for it to report a distance in inches

  • I always use this method when i use the tracker and ball doesnt fit in the hole.
    But now i have a part that has 400 holes and i want to find an option where i can maybe take 1 hit and no sample hits.
    maybe by building or inspecting to a line like the other guy had mentioned and getting a tp to the line or a 3d distance.
    ive tryed googling and searching here but i cant find anyhing about it so i read this thread and it had a similiar question so i thought id comment in here and maybe someone with experience similiar to mine can help
    thank you in advance ;-)

    Readpoint is not what you're looking for; that function returns the XYZ of the current probe location.

    What it sounds like you are interested in, is the Location of a Circle. Due to the circle size, it sounds like you are planning on using a 1-hit circle -- this is fine.

    1. Import and heal your model
    2. Create your alignment as indicated by your drawing
    3a. Use Auto Circle and choose your target/nominal from the CAD with a click of the mouse, or by entering the XYZIJKD manually.
    3b. Change the number of hits to 1
    3c. Change the number of sample hits to 3
    4. Create a Location Dimension with the appropriate axes and tolerances.

    Program is done.

    Execute the alignment. When the execution reached your 1-hit circle, you will take the 3 sample hits on the surface around the hole. Then you can nest the probe in the hole and take a single hit.

    Assumptions: you are using PCDMIS v2009 or later
    : the surface around the hole is flat
    : the hole's vector is perpendicular to the face.

    Good luck!
