IGD v.3.8.61 has been released on May 23rd, 2022, and it is available to download now. Go to Help -> Check for updates… to update your current installed version of IGD. This new version includes the following features and/or enhancements:

  • Implemented new geometries of external and internal spur and helical gears with chamfered edges.
  • Implemented other small changes and overall improvements to the program as suggested by the members of the consortium.
PREVIOUS VERSIONS:

    IGD v.3.8.54

    • Updated graphical IGD libraries to the latest version.
    • Implemented new geometries of external and internal cylindrical gears generated by skiving.
    • Implemented the comparison of profiles of skiving cutters in XYZ format.
    • Added a new feature to compute and show the deviations of the profiles of cylindrical gears with respect to the reference involute profile.
    • Fixed issue with TCA of helical gear drives with free-form designed tooth surfaces.
    • Implemented other small changes and overall improvements of the program as suggested by the members of the consortium.
    • Various general “under the hood” improvements.

      IGD v.3.7.166

      • Fixed bug when importing ODB energy results.
      • Implemented other small changes and overall improvements of the program as suggested by the members of the consortium.

      IGD v.3.7.161

      • Fixed representation of the contact pattern in the summary of TCA of face-gear drives.
      • Implemented the advanced definition of double-spur gears.
      • Various “under the hood” improvements.
