After exploding the assembly, when I try to edit the placement of a sub-assembly in a particular computer at school the placement of the sub-assembly is edited. But on a another computer when I try to do the same only one component of the sub-assembly at a time is moved. In the assembly I would like to specify that I want to edit the placement of the whole assembly or for a particular part of the sub-assembly, can someone tell me how to specify this, thanks. I'm using WF2 on both computers. Thanks.
