I have encountered some lines that appear in the data manager; however, they do not exist in the actual drawings, and they wont zoom into the actual location in the model space. Is there a way to delete these unexisting lines from the data manager? I have tried purging the drawings, but to no avail. They still can't be erased.
Open the database(ProcessPower.dcf file in the project) with SQLite Manager (FireFox plug-in) and delete the lines.
Purge the drawing (check the box that says purge zero length....)
then run "Audit"
