Re: I need to globally remove excess layer styles or layer filters.

Thanks, Steve, I tried purging but had no success. It was a VB routine as I used VBRUN to execute it.
I did find an Autodesk command called "FILTERS" and it has a counterpart in IntelliCAD!

So just type in "FILTERS" at the command line and a dialogue pops up. The names on the right are deleted and the names on the left are keepers with arrow keys to move them back and forth. Works like a champ.
