You have choices, make the right choice
Cartesian Distance
In this example, the “Primary Datum” is the same as the “Spatial Rotation” and “Secondary Datum” is the same as the “Planar Rotation” inside an alignment. Selecting “Parallel To” or “Perpendicular” specifies the axis direction. i.e. the “X”, “Y” or “Z” axis
How To: Operation Planner
Do you manufacture parts in distinct operations? Is the part also inspected after / during each of these distinct manufacturing operations? Are you creating unique CMM-Manager programs for each operation? If so, there is a better way
Alignment with Offset Plane
The offset plane can be used in an alignment construction. A good example of an offset plane is cast datum points, where they are rarely on the same plane.
