About Synchronizing Transaction Changes
You can automatically synchronize the external ECAD tool database with the transaction changes made in Creo View ECAD Validate.
You can synchronize Creo Parametric MCAD designs with changes made in Creo View ECAD Validate. When communication is enabled, you can automatically apply changes to a transaction, send a notification about changes in the status of a transaction, or both. Set the transmission preferences to accomplish these tasks.
