CHECK_ALL_MODELS
<Y/N>
Specifies whether Creo ModelCHECK must check all the models of an assembly irrespective of whether the models have been changed after they were retrieved or the value of the MC_ERRORS parameter.
Y—Always checks all models ignoring the setting of the SKIP_MODELS configuration option.
N—Checks models according to the setting of the SKIP_MODELS configuration option.
 
* CHECK_ALL_MODELS is only applicable to interactive mode of Creo ModelCHECK. It does not work for regenerate and save mode, since in these modes Creo ModelCHECK runs only on the top level assembly or on the component which you save or regenerate.
