At some point or another you’ve probably had some leftover imported categories in a Revit project and couldn’t seem to delete them.
In most cases you can remove these using Manage > Purge Unused, or by deleting the last instance of the import in the project. However if a detail or model group is using an import instance you will be unable to purge the instance from the project.
If some imported categories remain and they don’t appear to be in use, check the project for the following:
1. Under Project Browser > Groups > verify if the project contains any detail or model groups.
2. If so you can expand to highlight a group > right-click > Select all Instances > In Entire Project. Then temporarily delete the group instance[s] > Manage > Purge Unused.
3. See if the import instance now appears under Families > <Import Instance Name>.
If not you can undo and test selecting \ deleting another group to isolate which one may contain the import instance.
Nice tip, thank you very much.
However, I am experiencing some different problems trying to purge unused groups in Revit: When I try, the program advices that the action caused the suppression of the workset that the group belongs to, and the only options are to cancel or to make elements editable. Unfortunately, when I press "make elements editable" nothing happens, and I cannot close that window until I hit the "cancel" button.
Is there a identified cause or even a solution to this problem?
Your feedback would be greatly appreciated.
Regards,
João.
