The function ProDrawingDimAttachpointsGet() retrieves the entities to which a dimension is attached and the type of attachments. This is applicable only for dimensions created in the drawing mode.
Anyone knows the API to retrieve the entities to which a dimension is attached for model (solid) dimensions. Because above API is applicable for only drawing mode.
Over 8 years later, I have the same question! Looks like PTC has no intention of improving the API to include d# dims.
