IGD v.3.7.166 has been released on December 1st, 2021, 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:

  • 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.
PREVIOUS VERSIONS:

    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.

    IGD v.3.7.137

    • Implemented tip-to-fillet interference detection as a result of TCA.
    • Fixed computation of the profile shift coefficient of internal spur gears generated by a shaper.
    • Fixed representation of the 2D FE model with quadratic elements for the whole gear set.
    • Implemented -Export assembly- option for helical gears.
    • Implemented other small changes and overall improvements to the program.

    IGD v.3.7.122

    • Implemented computation of backlash in CURVIC couplings.
    • Improved the TCA approach for CURVIC couplings.
    • Implemented -Export assembly- for CURVIC couplings and spur gears. It allows the assembly of the gear set to be exported to main CAD computer programs.
    • Removed absolute positioning errors for TCA. All gear sets now implement relative positioning errors.
    • Fixed default case for hypoid and hypoloid gear drives.
    • Implemented other small changes and overall improvements to the program.

    IGD v3.7.93

    • Fixed bug that prevented projects of internal helical gears generated by shaper to load correctly.
    • Changed the approach of TCA for spline couplings to improve the speed of computations.
    • Implemented the analysis of errors of alignment for the TCA of CURVIC couplings.
    • Implemented other small changes and overall improvements to the program.

    IGD v3.7.89

    • Fixed bugs on existing features of IGD reported by the Gear Research Consortium members.
    • Improved TCA and FEA of CURVIC couplings. Rotation in CCW and CW directions can be now analyzed.
    • Implemented Load/Save of CURVIC couplings projects containing finite element models.
    • Fixed default cases of spiral and globoidal worm gearsets.
    • Implemented other small changes and overall improvements to the program.

    IGD v3.7.83

    • Implemented the geometry, TCA, and FEA of CURVIC couplings (further evaluation and testing needed).
    • Fixed bugs on existing features of IGD reported by the Gear Research Consortium members.
    • Implemented other small changes and general improvements.

    IGD v3.7.58

    • Fixed bugs reported by Gear Research Consortium members.
    • Implemented geometry of spur gears generated by shaper.
    • Implemented advanced definition of the shaper to generate external spur gears by shaping.
    • Fixed some minor bugs reported or detected within the last week.

    IGD v3.7.37

    • Fixed bugs reported by the RIT's Gear Research Consortium members.
    • Implemented the advanced definition windows for internal spur and helical gears generated by shaper.
    • Implemented the advanced definition window for splines couplings.
    • Fixed some minor bugs reported or detected within the last week.

    IGD v3.7.24

    • Updated viewport to the newest graphic library.
    • Fixed bugs reported by the RIT's Gear Research Consortium members.
    • Improved definition of spline couplings to allow a general definition as well as definition according to ISO 4156.
    • Fixed bugs in the advanced definition window of external helical gears.
    • Added highly crowned geometry for the shaft of spline couplings.
