How to use

The material editor can currently be accessed by:

  • Arch Workbench:
  • FEM Workbench:
    • The menu Models → Material → Material editor
    • The icon Material editor
  • Via python:


import MaterialEditor


  • Browser button: Opens the contents of the URL property in a browser
  • Material card: Allows to choose a preset to fill in the fields
  • Open: Opens a .FCMat file
  • Save as: Saves the contents of the editor as a new .FCMat file
  • Preview: Not implemented yet
  • Properties editor: Allows to edit the contents of the material properties
  • Add property: Allows to add a new custom property
  • Delete property: Deletes a selected property. Only custom properties can be deleted


  • The OK and Cancel buttons have the same effect when the Material editor is not used to edit directly the material property of an existing object.
