Can’t move objects individually

Hello.

I think it's a rudimentary thing, but I have a problem.


APP:Ergonomics Evaluation

Text:Ergonomics Evaluation Essentials: Managing Manikin Attributes

File: Exercise_AttachingObjects.3dxml


I try to attach an object to a manikin, for example, when I try to move a AirCylinder object,

Even if I selected the ‘robot is set to Snap Automatically’, but all objects were selected as shown in the picture, and I couldn’t  move individual objects.


How can I move objects individually?


Best regards
