How to reference a Drawing Model back into the 3D model from which it was created from?
In the 3D mode under the References dialog box go to Tools > Attach. In the Reference Attachment Settings, select the Model, in this case will be the Master Model. Then under "Orientation" expand the "Saved Views" and select the Drawing Model of your choice, set Nested Attachments and Nesting Depth as desired, then hit OK.
The Drawing Model should be now referenced in the 3D model.
Actually that doesn't really work. When trying to place the reference, one must either choose an insertion point, or click coincidence. Whatever you are using, it won't be at the place where the section is made, and it's not flat either.
Things are getting even more strange when you set nesting to live nesting, because then you are cutting through the other sections you might have referenced as well.
