Modifying Component Dimensions

Page 37:

You can edit the dimensions of a multiple-configuration component in the assembly or

drawing environment, regardless of which configuration is active in the component

document.

Previously, in an assembly or drawing, you could not edit the configured component

dimensions unless the configuration you were editing was also the active (open or last

saved) configuration in the component document.

In an assembly with a component that has multiple configurations, double-click a dimension

that has a different value for each configuration. In the Modify dialog box, you can set a

new value for the dimension and specify to which configurations the change applies.

I tryed but nothing.

Where I wrong ?
