Model Accuracy in ModelUPDATE
You can specify the type and value for the model accuracy. In the ModelUPDATE mode, Creo ModelCHECK automatically changes the accuracy to this value if the accuracy is not within the acceptable limits.
Use the following format in the start configuration file:
MU_ACCURACY [type] [value]
where
[type] is the type of accuracy (relative or absolute).
[value] is the value of the accuracy.
For example,
MU_ACCURACY RELATIVE 0.001
