Ground plane setting using common axis between 3 control points

Currently when defining a ground plane with control points you have to have a known distance.
What would be a great addition to this is a way to define a ground plane (Flat surface, and origin) with a set of 3 control points with no known coordinate inputs.RC will take this and then try rotate and translate the scene to match the common plane of those 3 control points.

This would be helpful as defining the ground plane currently is a lot of work for scenes with no mesurement ques

The define ground plane tool is irritating to get right when a scan is at a strange rotation. even though the subject of the scan is a flat surface. this tool also does not carry through to future alignments, so having it set via control points would be a big plus.

Thanks,

Of course this is how it should work. Just like SynthEyes. Select 3 points and align ground to plane.
