Delete Unused Materials?

[Steve Wojtynek]

I typically create new or add ArMaterials (from a library of materials I'm building) to whatever model I'm currently working on.  I change my mind on materials along the way and when I'm finished, I typically have about twice as many materials than the ones that are actually assigned to layer names in the model.  Is there a way to "purge" unused materials along the way or when finished?

Use AutoCAD's purge command.  The AccuRender materials are just AutoCAD materials with some extra data on them-- they have "accurender" as a prefix.

Right click on accurender's material list and select Refresh after this to manually refresh the list.
