HI @luis.moreiraLEUNF 
Sorry that I misunderstand your question. I am not very sure the Rotate way you want. I will list other two ways here, please see if it can solve your problem.
Way1: Rotate at the dragged part
1. Select the parts you want to rotate
2.Left Click to Drag the selected parts
3.Keep left Click, Right Click to Rotate
 
Way2: Rotate at the central point of the group
1. Select all the parts you want to Rotate -> Right Click -> Select New Group -> Type any name to the group
2. In Design Manager window -> In Browser Tab -> Select View as Groups -> Select the Group you have created
3.In Inspector window -> Click Rotate command in the Quick Action
Attach the video here to show them clearly.
