Object Type in the To Do List: Boundary curve
Meaning: The boundary has moved or been redefined and no longer intersects the object to be bound, or the boundary is on the To Do List and needs to be updated.
Verify that the boundaries intersect the landing curve of the object being created. If not, select different boundaries.
Update any input information, including boundaries, that is on the To Do List.
If the problem persists, report steps taken to your support group.
