Excuse me, in SolidWorks, I put a part with configuration into an assembly. Why did I change the internal model of the configuration, but it didn't change during the assembly?

The reference configurations in the assembly are different. You cannot change the configuration of parts! If you want to change? Directly in the setup tree of the assembly? Right-click the part to be configured, and select Part Properties-Modify the referenced configuration (lower left corner), as shown!
