About Validating Chains Dynamically
When you create or edit chains Creo Parametric dynamically validates the chain. If the chain is valid the Dynamic validation box is automatically selected. When dynamic validation is enabled, adding new references to the active collector or removing references from the active collector does not make the active chain invalid. Note that you can disable dynamic validation at any time.
If the chain is invalid the Dynamic validation box is automatically cleared. When dynamic validation is disabled, you can add new references to the active collector or remove references from the active collector without restrictions. However, this may make the active chain invalid. If the chain becomes invalid then the Dynamic validation box becomes unavailable.
