I need some help importing and exporting custom layer property filters. Long story short, we XREF a lot of mechanical equipment in our models and when we create a structural drawing make all of the mechanical item print in a light ghosted color. I created a lyer property filter with a huge list of all the possible equipment prefix's like *cl-* *tk-* *rv-* and so on to filter out all the equipment layers. It took a long time to create, so I want to export it and import it into future drawing. Is anybody aware of a way to do so? Thanks.
