The simplest way to open .gad-files in GeoDict is by selecting File → Open Structure (*.gdt, *.gad) … in the menu bar, or by clicking its icon in the Toolbar ( ). This way, the .gad file is imported with the domain options specified in the Domain parameters. (see the Edit Domain command)

However, to load the .gad file with values different to those specified in the Domain, parameters, the Import GAD Objects from File command may be used.

Click the Options’ Edit… button to open the Import GAD dialog. Browse… for the .gad file to import. The domain information is automatically entered from the Domain in the file and may be changed.

By changing the side Length and Origin, it is possible to import only a cut-out of the material. By changing the Voxel Length, it is possible to increase or decrease the resolution of the imported 3D structure.

By choosing Resolve Overlap, the overlapping areas will be assigned to the closest object as described here. In this case, it is then again possible to Mark Contact Voxels with a special material ID.

If Delete Invisible GAD is checked, all objects which are completely outside of the chosen domain will not be imported.

It is also possible to rotate the GAD objects directly when importing, achieving the same results as with the Rotate GAD Objects command.
