Edit Couplers

  1. If the Couplers panel is not currently displayed, select the desired coupler by clicking on it in the Project Browser or in the modeling window.
    The Couplers panel is automatically displayed.
  2. Select the number of joints to constrain.
    Note: If the selected coupler is a pair entity, first distinguish between the Left and Right tabs in the panel, and then edit the properties. When defining a pair coupler, use pair entities for the joints.
    Tip: Check the Symmetric properties option to make the coupler properties symmetric. Once this option is activated, MotionView will ask you which side of the values of the pair entity (left or right) is to be used. Selecting any one side will make values of that side as “master” and the values of the other side will gray out and follow the values on the master side.
  3. Click on the Joint 1 collector and pick the desired joint from the modeling window, or double-click the collector to open the Model Tree (from which the desired joint can be selected).
  4. In the same manner, click the Joint 2 collector and pick the second joint for the coupler.
  5. If the number of joints to constrain is set to 3, repeat the same step for the Joint 3 collector.
    Note: If any of the joints are cylindrical, select the type of the displacement to be controlled by using the drop-down menus located to the right of each selected joint on the panel (translational or rotational).
  6. Click the Properties tab.
  7. In the case of a two joint coupler, type in the displacement ratio between joint one and joint two in the appropriate box. In the case of a three joint coupler, type in the two displacement ratios between joint one and joint two, and between joint two and joint three.
