I am trying to take a measurement from the apex of a constructed 100 degree cone tangent to a measured sphere. I'll attach an image to give an idea of what I'm tryin g to do. Can this be done in PC-DMIS?
You can do it by a little trig, from the sphere center (If the cone is aligned on the sphere center, it's a 2D problem between a line and a circle).
So the line is at 50° (half angle), so the radial line is at 50°.
The contact point between the line and the circle is Rcos 50 on X and R sin 50 on Z.
Then the cone vertex is (5cos50)*tan(40) + 5sin 50 on Z from the sphere center.
