CALYPSO recognizes automatically if inspection characteristics and measuring elements have already been created from PMI, since the PMI have a certain identification name internally. CALYPSO does not generate the measuring elements and characteristics more than once.
However, if PMI has already been created and then deleted, the status is retained. This means that the entire CAD model must be imported once again to create it again.
If too many inspection characteristics or measuring elements are created, too many elements/linked geometries are stored behind the PMI.
