AutoCAD Inventor :: Distinguish Hole Features From Other Circles In Drawing / Add Centermarks

I'm attempting to use VBA to put center marks on each hole in my drawing. So far I have the following

Dim oIntent As GeometryIntent Dim oCenterOfPart As Centermark
'Add center marks to base view For Each oCurve In oBaseView.DrawingCurves '
<- need to identify Hole Features If Not oCurve.CenterPoint Is Nothing Then
If oCurve.CurveType = kCircleCurve Then 'CurveTypeEnum

[Code] .......

oBaseView is the DrawingView object representing the base view the code just placed. I also used VBA to place the projected views oTopView and oRightView. I want to add center marks to each hole when viewed from the end (as circles) and add centerlines when viewed from the top or side (as hidden lines).

I will be iterating through several models representing various handhold styles. The feet can be in many orientations, 99% of them are paralel to one of the origin planes (XY,YZ, or XZ).

This is what my code generates: (The centermarks that are selected are the ones I don't want the code to generate).  This is what I WANT the code to generate:

1) How do I distinguish whether a circle curve originated because of a hole or because of another cilindrical feature?

2) How to I identify the corresponding hidden lines in the other views so I can add a center line?
