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 PCDMIS? Capture 6365.PNG

I am trying to measure the "10.744" dimension in the picture above. The blue lines are constructed and are not measurable features.
Thanks

I would recommend doing this using several 2D evaluations. You can take a line on each side of your cone and then click Insert> Feature> Constructed> Circle. From the dropdown select "Tangent 2 Lines". Key in your gage ball diameter and dimension the circle to the cone vertex, add radius. I would also recommend doing this at a minimum in both X and Y workplanes

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.
