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

Creation stages / Use:

Click the icon or select Mechanism > Other joints > Sphere on sphere... command from the drop-down menu.

1. Select the first rigid group.

2. Select the second rigid group.

3. Select the center of the sphere of the first rigid group, either by clicking the center point, or by clicking the sphere.

4. Enter the diameter of the sphere of the first rigid group.

5. Select the center of the sphere of the second rigid group, either by clicking the center point, either by clicking the sphere.

6. Enter the diameter of the sphere of the second rigid group.

7. Check or uncheck Unilateral This option allows to have a non-permanent contact between the 2 spheres, from the side chosen when the plane was selected. If this option is checked, you will be able to move the sphere rigid group until it touches the other one. The rigid groups can be separated, but can't intersect themselves.

8. Check or uncheck No slipping. When No slide is checked, the sphere rolls in relation to the other sphere. Otherwise, it slides.
