  • New 'GiD White Vectorial' theme
  • macOS: GiD build on macOS 10.15 Catalina, solved USB access problems.
  • macOS retina support.


  • Each geometry entity store its mesh (avoid re-mesh if was meshes, update the mesh if required, copy also the mesh when copy a geometry, etc.).
  • IFC geometry format import (BIM standard format)

  • Undo enhanced (redo, undo last command, use backup as starting point, not lost history saving model, copy commands from undo multiple window, etc.).
  • Repair check contact volumes integrity, and do some repair in simple cases


  • Plugin to export results in shapefile format (GIS)


  • New option Convert Visible iso-surfaces to Cuts.
  • Fix lack of memory bug with results cache
  • Volume rendering: again functional and with some additions.
  • Fixed bug when cutting multiple meshes.
  • Corrected problem when importing multiple VTK files.
  • HDF5 corrected some errors when reading and writing results.
  • skipping steps when reading results: added option to read every X steps.


  • Tcl/Tk updated to 8.6.12 version

  • linux and macOS: $GID/tk_widgets_demo script added to show a collection of tk widget demos and its source code.
  • CustomLib
    • customlib problemtypes don't require embed used procs in the xml spd file.
    • correct_local_axes_with_lines command to modify assigned local axes based on the direction on some curves.
  • New GiD-Tcl events:
    • GiD_Event_BeforeCalculate, GiD_Event_AfterReadPreferences, GiD_Event_AfterSavePreferences, GiD_Event_BeforeExit, GiD_Event_AfterDataManagerSetCloudFolder

    • GiD_GetUserSettingsCommonDirectory ?-create_folders? , return the main user GiD folder
    • GiD_Project backup save|read ?-ignore_must_save_flags? <name>
    • GiD_Mesh list face (e.g. "GiD_Mesh list -normals_dotprod_threshold -0.9 face" to identify problems)
  • New Tcl sub-commands:
    • GiD_Info bounding_box new optional flags ?-geometry|-mesh|-post? ?-layers_off_also?
    • GiD_Info mesh nodes | elements new option -array2 : Instead of a plane list it returns the results as a list of objarrays (more efficient).
