A planar joint is a three degree-of-freedom constraint. It constrains a plane on one
body (Body 1) to remain in a plane defined on the other body (Body 2) connected by the
joint. The planes are defined by the X and Y axes of the markers defining the joint. Body 1
can rotate about Z axis and translate along the X and Y axes of the marker which is used to
define the constraint.
-
If the Joints panel is not currently displayed, select the desired joint by
clicking on it in the Project Browser or in the modeling window.
The Joints panel is automatically displayed.
-
From the Connectivity tab, click Body
1 and pick a body from the modeling window, or double-click Body 1 to open the Model Tree (from which the desired body can be
selected).
Note: If the selected joint is a pair entity, first distinguish between the
Left and Right tabs in the
panel, and then edit the properties. When defining a pair joint, use pair
entities for Body, Origin, etc.
-
Similarly, click Body 2 and
select the desired body from the modeling window (or use
the Model Tree).
-
Click the Point
collector (under Origin) and select a point from the modeling window, or double click the
Point collector to open the Model Tree (from which the desired point can be selected).
-
Specify the properties of the constraining plane of the joint .
If editing a compliant joint, see Edit Compliant Joints or Bushings. To edit user-defined
properties, see Edit User-Defined Joints.
