Why copy of drawing influence on origin?
Hi,
I'm working with Creo Parametric 6.0 and I'm making drawing of simple part. When I've done this drawing I've created a copy of this origin drawing (File->Save As->Save a Copy). Then I made some changes inside the copy (mainly deleting some dimenssions) and i I saved it. When I opened the origin drawing I realized that dimenssions which I remove in copy have been also removed in origin drawing.
It looks like the changes made in copy influence on origin file. Is there some way to turn off this influence?
Thank you in advance for all answers!
