Projecting points back to a plane correctly using a tracker

Hi Guys, here one for you, regarding best practice and use of a laser tracker!!!!!!!

Basically we have points to measure on planes that are an angle. because we are using an adaptor place on the hole we are 10mm from the surface.
I believe the correct thing then to do is to measure a projection plane then send the measured point to the surface via the nearest point as such.
A colleague believes that this is unnecessary and a straightforward system translation will do.
My belief is that although this is would be close it would be not correct or best practice as if the plain was at compound angle the projection would be incorrect...
your feed back would be much appreciated-TED

  • You can measure the plane, then project points. You can do it with the function "project", or calculate them by assignments
    ASSIGN/V1=PL1.XYZ+CROSS(PL1.IJK,CROSS(PT1.XYZ-PL1.XYZ,PL1.IJK))*SQRT(DOT(PT1.XYZ-PL1.XYZ,PT1.XYZ-PL1.XYZ))
    Then, you can create generic point with V1.X,V1.Y,V1.Z and PL1.I,PL1.J and PL1.K
