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?

  • I don't understand why it gives a different value when intersecting the auto cone with the plane, but the result from constructing a circle at a certain height might be explained by the fact that the cast point for a constructed cone and an auto cone are not the same! What are your other parameters for the "circle at height" (which point, which vector)?



    - Can you elaborate on the cast point for a constructed cone and auto cone are not the same........what do you mean by cast point and why wouldn't they be same?

    - I have tried origin, start of cone, end of cone, cone vector, +/- of the axis in which the cone lies etc.
