Hello All,
I want to select the non zero length CBUSH elements according to their CIDs, i.e. elements having local coordinate system, global coordinate system and no coordinate system. I tried with my code, but it is giving global coordinate system value (0) if the CID field is empty. Which command should i try?

As shown in above snap, CID field is empty. but it is giving value 0.
Please help me on this.
Regards,
Sanket
