Constraint working mode
Part constraints can work in two modes: as constraints or as measurements.
In constraint mode, the value assigned to the constraint
drives the actual position of the constrained geometry.
In measurement mode, the constraint value only reflects what
can be observed from the actual position of the constrained geometry.
Values:
catCstModeDrivingDimension
Specifies that a constraint should work as a constraint.
catCstModeDrivenDimension
Specifies that a constraint should work as a measurement.
