About Subassemblies
You can use Creo Expert Moldbase Extension to create and delete subassemblies. Each subassembly consists of a skeleton model with all the major datum features of the main assembly. To modify the skeleton, the EMX main assembly must be the active assembly.
Separating a base assembly into smaller subassemblies has the following advantages:
• Multiple designer engineers can work in parallel on a design.
• Regeneration of smaller subassemblies is faster.
It is recommended to save the original assembly which contains the desired set of subassemblies.
When you place a new component in an existing subassembly, make sure to set up the subassembly structure first. You cannot move a component to another subassembly when you modify it. First delete the component, and then recreate it.
