Meaning: The opening does not have any range values defined and therefore you cannot select the cutout when using range queries.
Recovery:
-
Select the opening (cutout)
in error.
-
Select a property in the Properties View, and set it to a different value. Then, set it back to the original value.
If the cutout does not recompute and clear from the To Do List after you edit a property, the only other option is to have your database administrator run the Database Integrity Check in Project Management.
