Select 3d polylines with multiple numeric filters

[Anonymous]

Problem: Multiple numeric filters for selecting polylines. I need to select 3d polylines, which means my filters are 0 - "POLYLINE" 70 - 8 but I also need to select closed 3d polylines as well (9). I have tried -4 "" but to no avail. Also tried 70 "8,9" thinking it may be like "Line,Polyline" but that didn't work either. 70 array(8,9) but no good either Can I set up a filter that will allow multiple numeric filters or should I let the user select all polylines and scan thru the selection set for the 3d ones? Thanks, Jon

Hi Jon Use bitwise masked equals: 0 "POLYLINE" -4 "&=" 70 1 -4 "&=" 70 8 to select all closed 3d polylines... Cheers -- Juerg Menzi MENZI ENGINEERING GmbH, Switzerland http://www.menziengineering.ch

Thanks for the reply Jürg, I would like to select 3d polylines whether they are closed or open, not just closed polylines. These bitwise operators twit my brain.
