• You may check the settings in your option file for the "Precision Bores"
    Should be:
    Precision Bores NOMINAL
    Maybe in some case you need to set the precision to the ACTUAL
    Precision Bores ACTUAL

    Other clue also is that you need to check in the Paragon for all defined Nominal Bores in NBRWLD, it might be that there's conflicting values for Incbore & MMbore

    But this case is strange, even you extract the Isometrics in the Design; still using the same Isodraft application to process the Isometrics in Design module via IsoDraftMode.
  • My iso options file has Precision Bores NOMINAL like Rhel suggested and its working good for me. Let us know if that resolves your issue.
  • You can also "pimp" your Nominal Bore Table (NBRWLD with PURP BORE)- e.g. to have the diameter for the Ermeto pipes (precision pipe acc. EN 10305) or the SAE-pipe diameter.
    The same you can (or must) do with your Bolt Diameter Table (NBRWLD with PURP BDIA) if you have imperial and metric bolts in one Bolt Spec.

    Imho there can only be one table with purp BORE, but tables with purp BDIA will be recognized, even if there are more than one, right?
    Does anyone has some more information?
  • Dear alli am concerning also by this problem,bolt in 1/2" show 13 on iso BOM,-> 1/2 * 25.4 = 12.7 ,iso show 13 i want 14 for M14I try with creation of NBRWLD purp BDIAinside ,i have NOMINB with incbore 0.5 and mmbore 14on my iso setting,i am already on Precision Bores NOMINAL and Bolting  Units  METRIC but no change on my isonote:bold are define with old methodbolt are as spco present in my PSPECcould be i miss something or could be that this method is not compatible with old bolt methodthanks
