This command allows to create a revolute joint between 2 rigid groups.

Creation stages / Use:

Click the icon or select the Mechanism > Revolute... command from the drop-down menu.

1. Select the first rigid group.

2. Select the second rigid group.

3. Select the rotation axis. The direction indicates the direction of positive rotation of the 2nd rigid group in relation to the first, if this joint is used in a task.

4. Select a center point. This optional possibility may be useful in dynamics. The point chosen for greater calculating precision will be projected to the axis selected previously.

5. Check the multi-turns angle if the revolute joint needs to turn more than 180°. The time required for calculating may be long. In the event of a geometrical change, the rigid set returns to its initial position, then the number of turns is recalculated.

6. Enter the initial angle. This is the initial value of the joint, as represented in the design configuration. For example, if a circular actuator is designed with the rod half out and its initial value is 40°, TopSolid considers that the rod is out by 40°, if the maximum limit of the rod is 40°, the rod cannot turn the other way any further.

7. Check Limits to be able to fill in the minimum and maximum angles.

8. Viscous Friction can be taken into account by checking this option.
