Hi All,
I had some previously created drawing files.
I was trying to setup a sheet set, by creating a blank sheet set and then by using the option "Import Layout as Sheet". I imported all the sheets. Then I had to edit the Sheet title and sheet number in each sheet's properties. However, the Rename Options to rename layout tab and the file seems to be disabled for all the sheets in this sheet set. (Please see the attachment)
What could be wrong?
