Hi, this is like second part of my originally question how to generally get points of type Objects for creating 3D reference plane by 3 points in assembly environment.
As the points for creating plane I can get StartVertex and EndVertex of Edges of Shells (of bodies in the Occurrences) .
The another issue is how to get object points of KeyPoints of 3D sketches. I cannot find any method to do this. I can get just their positions by SolidEdgePart.Line3D.GetKeypointPosition(), but I need COM object of that points..
