Advenced measuring principle

[[El...]]

Hi everyone,

Im trying to compare a surface profile (GDnT) but I have a few problems. I have to do the comparaison on the whole surface of the part (not only on one element like a plan or something else), so after the alignement, I created my reference surface on the CAD but I can't assign any measuring principle : I can't even select the mesh and 'fitting element' does not work correctly.

You can see my CAD in the first pic, then my 3d scan and my nominal surface.

Due to "green" color of a surface i presume you are doing it on wrong face - in other words - on your actuals there is no surface ( it should be grey ) - green means surface viewed from inside of a material.

If your scan is correct, then you have to select correct surface on model ( that side which is not viewable now )

Or your scan is not correct - missing thickness of material on actuals ( you have only a film and not thick material ) or your scan is from other machine, then you have to invert nominals.
