Interior Wall Thickness

I’m noticing inconsistent interior wall thickness on the floor plans and CAD files. A 2x4 drywall interior wall should never measure less than a 2x4 itself. I’ve had some interior walls measured at 2.75"! This is something the drafting team should have a little more consistency on regardless of what the laser data says. I can only align so much. I guess I need to specify all interior wall need to be a certain thickness unless otherwise noted.
