Geometries for Constraints Definition

The table below lists the constraints you can select and the possible geometric elements (product or axis system) you can select as first, second, and third element. For imported V5 joints with a driven kinematics command, a new constraint is created with computed supports. The second table lists the computed geometries to specify for each constraint type.

Note:
  • 1: 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 is fixed relatively.
  • 2: 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.
  • 3: Angle defines a 3D nonoriented 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 .

  • 4: Including multipatch surfaces.
  • 5: Defined with a selection of two or more components ( or ).
  • Hover over a constraint highlights the related geometric elements.
Important:
  • Only exact geometries are accounted for selectable geometric elements. If you try to select another type of geometry like polyhedral geometries, the selection is ignored and contextual commands are not available.
  • The Distance value used to differentiate two elements must be greater than 10-3 millimeters (1 micrometer) in normal design range and greater than 10-1 millimeters in large range.
  • The Angle value used to differentiate two elements must be greater than 10-6 radians (1 microradian) for normal and large design ranges.
