2023.1--Selecting Datum A as a plane; Datum B as a hole, Datum C as a hole.
"GEOMAJIC" States Datum C doesn't control any degree of freedom
Without Datum C, Datum B doesn't constrain the final degree of rotational freedom.
Am I wrong here?
Okay, so if these features aren't nominally square, and indeed the datum a isn't nominally flat then iterative would probably be the technique to use.
Are the datums defined as datum features or datum targets?
If datum targets then use iterative, then create constructed alignment features (in effect a plane, line or point based off the current alignment) then assign these as datums for geo tol.
Constructed plane - alignment (then change which axis so you could pick yplus/yminus to get A.
Constructed line - alignment (then change axis for either X or z)
Constructed point - origin to create a point at the origin for dat c.
This is the required technique to dimension with geotol for an iteratively aligned part.
