Delete multiple model patterns

[Chirag Mistry]

Is there a way to delete multiple model patterns at one time...we had brought in some work from AutoCAD in revit and now the model pattern is filled with ****...is there an easier way to clean it up..other than going to settings selecting each and deleting ?

Thanks

same thing for line patterns have all $a$...line patterns from autocad. How to get rid of it ?

Fill patterns and Line patterns can be deleted from the Settings Menu drop down for each category, in their respective dialogue boxes.

or if they are not in use, can be purged from the project with File>Purge Unused

My understanding is that fill patterns and line styles are not purged.
