Has anyone attempted to scan manholes for as-builts with the r3pro v2? Not looking for elevation, we will have that from our survey as-built. Looking to get measurements for rim to invert. Tired of measuring down with level rods.

Rafal,
If the sewer is dry you would be able to get measurements from the top of the manhole to the bottom of the invert. The accuracy you should get is 5-10 mm using SLAM. You could also try flying the drone overtop the open manhole slowly to get sufficient measurements at the bottom of the manhole.
Why not save time and just use a handheld laser range finder?
