Find is DWG file is 2D or 3D

How does one find out if the current drawing is a 2D or 3D drawing in VBA.

It's probably something simple I missed so please, excuse my ignorance.

You can simple look at system variable EXTMAX and EXTMIN for their Z values. if the two Z values are different, the entities are not all in the same plane.

Thanks,

I knew it was something simple. I guess it's time to reboot my brains😉
