Auto Cone extracted from a COP

We have Romer arm here with an RS3 laser on it.

I am having issues with the auto cone feature. I want to do an auto cone and then generate a circle from the auto cone, either by intersecting with an existing plane or by using the cone feature under construct a circle and create a circle at a given height.

If I take individual auto points and construct a cone, I get the results that I expect. I have been doing it this way for a couple of years now. Recently I tried to incorporate the auto cone feature into my programs and I can not get smart as to what is going on with this command.

Ex. Part I am currently working on, if I construct a cone from individual points and intersect that cone with a plane or construct a cone at a given height I get the result that I am looking for....in this case a circle with a diameter of 7.194"( verified with a caliper ). Now if I extract the same cone via the auto cone command and intersect this new cone with the same plane as above, I get a result of 7.394" and if I construct a cone at a given height( same height as the above mentioned plane ) I get a result of 6.560"

Has anyone else experienced weird result like this?

I have contacted tech support twice on this subject and have yet to get any kind of straight answer on this?

  • Update: Had a team viewer session with a Hexagon Application Engineer yesterday. He saw what I have been seeing and was able to replicate the issue on some test parts at his facility. He has logged it as a bug along with a color mapping issue I found in 2016.

    On a side note, I also asked if I should be using BFRE to construct circles, cones, cylinders etc., etc. He said BFRE is for hard probed points, not laser scan points. Although he said it wouldn't hurt anything if BFRE was used, but that you wouldn't see any real difference in the results.
