I have 1 ProE 3D model file, i gave the name : base.prt. And i saved in folder "A".
Then i make new 3D model on new sheet in folder "B", and i gave the name : base.prt. I just copied the base.prt from folder "A" to base.prt in folder "B" with Merge/inheritance command, after that i applied a shrinkage command.
After that, i did "save a copy" the base.prt in folder "B" to be base_reff.prt still inside in folder "B".
Just "save a copy", there was no any add command, so the history between base.prt & base_reff.prt is absolutelly same.
then i continued use this base_reff.prt as mold Part and i did spliting to make core-cave.
but ufortunatelly, i after i check the properties in base_reff.prt, this file already got 2 times shrinkage.
although i double check the history of command in base_reff.prt is same with base.prt
