Measure steps generate sequences of probe motions measuring the specified geometric references (planes, cylinders, etc.) at certain points. You can either manually specify the measure points or let the system generate them automatically along the selected references based on the Measure step parameters. After a Measure step is created, the system constructs a Measured entity by copying geometry of measured references.

Construct steps let you create geometric entities (planes, lines, etc.) by referencing existing Measured entities. Constructed entities, in turn, may be referenced by Verify steps.

Verify steps let you verify dimensions and geometric tolerances by referencing the Measured and Constructed entities.
