Hi,
Try:
1. Suppress rigid group (eg. 2 components jointed to rigid group)
2. Then move one of the component
3. Unsuppress rigid group
The component will move to the place where it was before. This is awfull.
Would be nice if part/component won't come back to place after moving but stay where I moved it.
Right now the only way I know to move a component in rigid group is to:
1. Delete rigid group
2. Move component
3. Create new rigid group.
