How to show dimensions from External Copy Geometry in drawing view

Creo 3.0

I used External Copy Geometry to copy sketch geometry in a Skeleton model to a part model.

I want to show the sketch dimensions in a drawing view that contains only the part model.

Please reply as we(my team) are working on these part model finding some difficulty of calling external ref. dimensions to drawing.

Temporarilty we are adding driven dimensions and we don't like it.

Thanks a lot in advance
