‌There is also the condition file you have to setup to get things working.

Hi kevin

             condition file will pick those three files

  1. In config_init.mc    
  2. In config_init.mc  
  3. In start.mcs:

and according to ptc help file i have set the things but accuracy in model check is not updating in drawing.

what ptc help is saying is-

Following settings in ModelCHECK configuration enables to set a specific accuracy:

  1. In config_init.mc (first pane):        MU_ENABLED      Y
  2. In config_init.mc (second pane):  MODE_UPDATE    Y
  3. Is start.mcs:                                  MU_ACCURACY   ABSOLUTE 0.01

i have done all the settings as written but it is not working, i am not understanding which way i am going wrong.

Nimesh,

As you are setting the condition for ABSOLUTE accuracy, make sure config option enable_absolute_accuracy as yes. I hope setting this config option will  help you.

             It works with settings told by you but one thing which i want to mention is that, there is ACCURACY_LOW  and  ACCURACY_HIGH mentioned in constant file now if the accuracy set between these values in your start file then it will not show any error but if the accuracy is set beyond this limit then modelcheck will ask to update accuracy and in this way it works..

Nimesh,

Did you get a chance to test the option in my last reply? If that worked, kindly mark the appropriate reply as correct answer to post.

How to change accuracy value below min allowable accuracy(0.0001) in creo3.0

If you want to go through model check then you have to set its value of accuracy low  to 0.00001 (say) in file named mm.mcn or inch.mcn and is located inside constant folder and then run modelcheck if your accuracy is beyond the range then model check will popup an error message..

You can also lower the minimum allowable range in Creo by entering a (very) small number for the config option accuracy_lower_bound.

From the help documentation:

accuracy_lower_bound

value (from 1.0e-6 to 1.0e-4)

Enter an accuracy value to override the default lower limit of 0.0001. The upper limit is fixed at 0.01.
