How to create independent copied objects in CST MWS

Hi..
For instance, I create a object by copying from the existing object either by scaling/mirror/transform/rotate options. If at all I want to change the geometry of the copied object, say length, the geometry of the original object also gets changed.
Please help me in creating independent objects so that i can able to change the dimensions as i want.

using local coordinates while defining each object we can achieve that
