The property
IpfcFreeAttachment.AttachmentPoint returns the attachment point. This location is in screen coordinates for drawing items, symbol instances and surface finishes on flat-to-screen annotation planes, and in model coordinates for symbols and surface finishes on 3D model annotation planes.
The method
IpfcFreeAttachment.View returns the drawing view to which the attachment is related. The attachment point is relative to the drawing view, that is the attachment point moves when the drawing view is moved. This method returns a
NULL value, if the detail attachment is not related to a drawing view, but is placed at the specified location in the drawing sheet, or if the attachment is offset to a model item or to a 3D model annotation.
