I have a part. Imagine a 1" thick disk 3" OD the diameter is actually a cone, so top of disc is 3" and bottom of disc is 2.5" just to get an idea of the draft profile. The top of the disc isn't a sharp point to the top surface but has a continuous radius around the OD. How should I measure the OD of the radius, which is the OD of the part on the print?
I would measure 4 cross sections and evaluate the radius size, that or using the nominal geometry measure and report as profile.
But it first depends on the callout for said feature.
Maybe a caliper or micrometer depending on tolerances. Or if you have a scanning probe "maxindex" will be your friend here...if I'm understanding your situation correctly.
Callout is the outer diameter of the disc, and I need it to establish a secondary datum. I was able to sample the radius on the diameter and find the center point then drive vector points to the theoretical tangent and construct a circle as the OD. How can I section the part and drive hits on the section? Like section a sphere and drive hits to a circle?

Then switch to Curve Mode (Link:
Switching Between Curve and Surface Modes (hexagonmi.com)) to select those lines/curves from the model when programming auto features. Curve mode will select the polylines when you click the model. Surface mode (the default) will select the surfaces when you click the model.
When you are done using the section cuts you can hide or delete them using the CAD Assembly Dialog ( link:
Working with Assemblies of Parts (hexagonmi.com) ). Each CAD section you make will be listed as a separate part in the assembly. Either un-check them to make them hidden, or right click and select Delete to remove them.
