Good morning, the datums defined on the customer print are a bit confusing and may not be defined correctly (big surprise).

Datum A = Plane

Datum B = Hole

Datum C = Axis between 2 opposing studs the location of which is defined as basic in the X,Z plane from datum B. I have picked up the diameters of both studs and created a 3d line between them. Then I created a point at the midpoint of this line to use for Datum C.

Datum A is leveled to Y Pos

Datum B is constrained to X=0.0 Z=0.0

I believe the part now has to rotate around datum B until it gets as close as possible to the basic location of datum C. (Best fit for C only rotating around datum B).

If the above interpretation is correct what is the correct alignment method to "clock" the part and remove the last remaining degree of freedom? BTW I am using a CAD model and V4.0 for todays festivities.

Thanks !!!
