FAROscene transformation local to global coordinate system

I've got a question how to transform in SCENE point cloud of matched several scans that are in local coordinate system to the global coordinate system (EPSG: 2180).
It's very important for me because without this operation it will be hard to compare those data from two source for the same area - from terrestrial and airborne laser scanning.
I use 4.7.1.2 version of SCENE. I've got manual for this version of SCENE but is there any tutorials that describing step by step how to do this operation (transformation from local to another coordinate system - here EPSG: 2180)?
I would be very grateful for help!
Sincerely
