how to select the arc by a named center reference point?
sir,
created a 3d part with a hole in it.
added a reference point to the center of the hole named p1.
need a api that will select the arc of which reference point p1 was constructed to add constraints.
hope to add center marks to arc in a drawing view.
-regards-
quick
