Api Origin Indicator in centermark

[Rossi_Ing]

Hi all, i am an engineering student an I'm writing a vba code to create an Inventor dwg.
I'd like to know if is it possible to attached the origin indicator (needed to make an Ordinate Dimension) in a centermark of a drawing view. The centermak is a point representing the origin of the assembly I'm projecting on the dwg and its attached entity is simply a workpoint.
I'm able to create an intent for the centermark (sheet.creategeometryintent(centermark)), but when I try to create an origin indicator drawingview.createoriginindicaroe(intent), I receive an error. Sorry for my English, and thanks a lot for any kind of suggestion.
