Angular Position Constraint

Angular position constraint is applicable to line and line segment types. In fact, this is a dimensional constraint that creates a driving dimension fixing the angular position of a linear object in its initial state relative to the OX axis in general sketch coordinate system. The angular position ranges from 0 to 2\(\pi\). In order to fix a direction, call GCE_AddUnaryConstraint with GCE_ANGLE_OX constraint type. Unlike GCE_HORIZONTAL and GCE_VERTICAL, this constraint type does not permit to flip the line direction vector by 180 degrees. As this is a dimensional constraint, the line angular position can be changed by calling GCE_ChangeDrivingDimension.
