Modeling a jacketed pipeline (7 core/internal pipes). Model was imported one pipeline at a time into CAESAR II via pcf file generated from Catia.

To model an internal support, we CNode the internal pipe to the jacket pipe. When we do this, the internal pipe shifts (coordinates change) automatically.

We had never encountered this issue before. Any help or insights would be appreciated. We are using Caesar II 2017. Please see attached picture and CAESAR II files.
