Use of Points Projection during Best Fit
From ArcoWiki
It has been added the possibility to limit the calculation of the alignment of BEST FIT and RPS only to selected surface when defining the nominal point.
The default provides projection of the points on whole model, to activate the limitation you must change, in WhiteStar.ini, the entry:
Best Fit project on all model=1 //0 = projection only on the selected surface.
