Curve Tweak function has changed in Creo 12

After updating to Creo 12, we noticed that the behavior of the Curve Tweak function has changed compared to Creo 11. Is there any configuration, setting, or option that would allow us to restore the previous behavior from Creo 11?”

    Hi @PerForsman,

    The change in Curve Tweak behavior in Creo 12 compared to Creo 11 can be controlled via a hidden configuration option: USE_PRE_CREO12_CURVE_TP. By default, this is set to NO, which enables the Creo 12 behavior. Setting it to YES in your config.pro should restore the pre-Creo 12 (Creo 11) behavior: USE_PRE_CREO12_CURVE_TP YES
     

    ⚠️ Disclaimer from CreoSite: The hidden options are usually provided for internal use by PTC’s QA department during the development of new releases and are normally not intended for customer use in production. Be careful using these options — they are unsupported, may make your system unstable or your models corrupt, and many hidden options may not be available in future builds of Creo.
     

    I found this information on Olaf Corten’s CreoSite.com: All config.pro options – Creo Parametric 12.4
