Select 3d polylines with multiple numeric filters

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 "<or"
70 8
70 9
-4 "or>"
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

 

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.

Regards,

Jon

 

Welcome...¦-)

In this case...
0 "POLYLINE"
-4 "&="
70 8

Cheers

 

Thanks Jürg, that worked a treat.

Glad to help you...¦-)
