I would usually fake in a level loop using the vertical angle from the gun but I'd really like to know how to constrain by just using the measurements imported. If I set a pair with GPS, then set up to tie corners, how do I force TBC to ignore the vertical value so I don't have to stare at this annoying 0.16' vertical bust?

Any help is appreciated. Still trying to migrate from Starnet but encountering little difficulties like this.
