To Redefine a Merged Part
You can redefine a merge or mold feature created using the Reference option. The redefinition allows you to replace the reference member with another instance from the same family.
1. Choose Redefine from the FEAT menu, or > , and select a reference member feature in the merged part.
2. Choose References and Done from the REDEFINE menu.
3. The system displays the INSTANCES menu, which allows you to select an instance or show or edit the family table.
4. Choose the appropriate option. As soon as you have selected an instance name, the system replaces the reference member with the new instance.
