SAVE_MC_PRE
<Y/N>
Y—Runs Creo ModelCHECK before a save operation. This option must be set to Y to ensure that the parameters that Creo ModelCHECK writes to the model are saved with it.
N—Runs Creo ModelCHECK after the save operation.
Set this option to N if you are concerned about data loss. In the unlikely event that Creo ModelCHECK causes Creo Parametric to exit prematurely, this ensures that models are saved before Creo Parametric exits prematurely.
 
* This option is applicable only in Save mode.
