Meaning: Retrieved the profile's cross section symbol but failed to retrieve the defining information about that symbol. The profile does not have available to it the geometry information of the cross section to continue processing. A relationship has been broken or the symbol information is no longer available.
Recovery: Verify that the cross section being used is still in the catalog and that the symbol is properly defined. If necessary re-associate the profile to the catalog cross section. If the problem still exists, report steps taken to your support group.
