Constraint Supports

The table below lists the constraints you can create and the possible geometrical elements (product or axis system) you can select as first, second and third element. Hover over a constraint to highlight the related geometrical elements.

Note:
  • 1: Angle defines a 3D non-oriented angle and the same result is applied when two different values respect the following formula: ||Angle1|mod 2PI -PI| = ||Angle2|mod 2PI -PI|.

    To keep the angle orientation, use Hinge instead of Angle .

  • 2: Including multi-patch surfaces.
  • 3: Defined with a selection of two or more components (product or axis system).
  • 4: The third element in a Hinge (hinge axis) does not necessarily belong to the same components containing the first and second faces, but must be parallel with the two faces intersection.
  • 5: The third element (symmetry plane) does not belong necessarily to the same components containing the first and second elements.
    Important: If the symmetry plane belongs to one of two components, the component will be fixed relatively.
