Hole pattern on conical part

Newbie here.  How can I create a hole pattern on a conical solid?

    Creo 7 model enclosed for reference. This is a quick and dirty example of one way to create this geometry.

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

    Maybe you have a more specific requirement?

    Sorry, I seemed to have mis-read this, completely ignored the word "pattern"...

    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

    Ok, I am able to create the datum point on the conical surface, but the placement dimensions are a problem.  For the cone, there would be axial dimensions and radial dimensions.  I can select the end of the cone as the axial dimension, but when I try to select a radial reference, the only one selected is a datum plane perpendicular to the axis of revolution.   What am I missing?

    You need to create the references required to set up the dimensions necessary to create the pattern you need. This will often require construction geometry. Post a graphic illustrating the pattern that you are trying to make.

     

    Are you attempting something like this, or something more basic? All of these holes go through the domed shell normal to the shell and they are created using patterns.
