REGEN_WRNS (Regeneration Warnings)
Y/N/E/W
Reports any warnings when a model is fully regenerated. These are typically problems that are reported in the Creo Parametric message window when a model is regenerated.
The mc_regen.mcr configuration file is used to specify the messages to search for and to determine whether a message is an error or a warning message.
Because this check can take considerable time, you run it with the ModelCHECK Regenerate command or in Batch mode.
