Duplicate DDP Set
Results in another design point set created with reference to the exact
same design points as in the source design point set (same design point
IDs, no duplication). Methods assigned to the source design point set
are not copied.
Paste
Paste design points that were previously cut or copied from another
design point set. This does not result in new design points created, but
a reference inside target design point set.
Remove
Removes a reference to a design point from its parent design point set,
but does not delete it from the database. However, if the reference
count is zero, then design point will be deleted too.
