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

  • You don't have to use AutoFeatures to build a single point circle.

    You can also use a Measured Single Point Circle. Whereas with an AutoFeatures, you are forced to take sample hits for each circle (but it is much easier to select from a CAD model), with a Measured Single Point Circle, you must select a 'reference plane', and then simply shoot the circle itself with a single hit.

    I find this really useful when I have a flat surface with many holes that I am trying to find the location of. Of course, when using this method, the diameter of the hole is going to be subject to the hole's circularity -- as the 'egginess' of the hole increases, so does the diametric uncertainty. And naturally, if your surface is not flat (typical with aircraft wingskins, automotive exteriors, or naval hulls), this technique won't work very well at all.

    search in the Help Menu for "creating a single-point measured circle feature". it has the how-to.
