To Create an Advanced Rigid Link
You can create a rigid link that connects points, vertices, edges or curves, or surfaces so that they move together as if part of a single rigid body.
1. Click
Refine Model >
Rigid Link. The
Rigid Link Definition dialog box opens.
2. In the
Name field specify a name for the rigid link, or accept the default name. Click the color swatch adjacent to
Name if you want to
change the color of the icon, the distribution, and the text displayed for the rigid link.
3. Select Advanced in the Type list.
4. Select a datum point or a vertex for the Independent Side. The independent side collector displays your selection.
5. Select any of the following geometric references in the model for the Dependent Side:
◦ Point—one or more points, vertices, point features, patterns of points or
intent points.
◦ Surfaces—one or more surfaces,
intent surfaces or a surface set. When you select
Surfaces,
Surface Sets appears on the
Rigid Link Definition dialog box. Click
Surface Sets to open the
Surface Sets dialog box to create a surface set.
|  You cannot select an entity that belongs to the independent and the dependent sides. |
6. Select a coordinate system in the CSYS area for the dependent side. The default coordinate system is World. Click Selected to override the WCS and select a UCS.
7. Click the UCS icon on the model to select it. The CSYS collector shows the selection.
8. Accept the default
Degrees of Freedom or select a combination of DOF for the dependent side.
