Hole pattern on conical part

All the picks are pretty much the same, pick  a hole placement surface and pick 2 references.

Maybe you have a more specific requirement?

This is one way to do it.

1. Create a datum point on the surface of the cone with the dimension references needed to pattern it.
2. Create an axis through the point and normal to the cone surface.
3. Create a local group of the point and axis
4. Pattern this group to generate the hole locations
5. Create a coaxial hole using the pattern leader of the pattern
6. Pattern the hole feature using reference pattern functionality
