With MeshGeo and ExportGeo-CAD, structures in GeoDict formats can be converted to a surface mesh. Additionally, meshes can be generated directly from grey value images, index images and volume fields. These features provide various  possibilities, such as importing µCT images and converting them into smooth meshes with sub-voxel precision. Moreover, creating triangulation from GeoDict index images allows the transfer of the object information from GeoDict’s structure generators to external software.

• MeshGeo can keep the mesh in memory after creation and allows subsequent smoothing and coarsening operations. For this, MeshGeo contains the additional options, Analyze, Edit, Smooth, Coarsen & Remesh, Repair Mesh, and Voxelize Mesh. Afterwards, the mesh can be saved in different file formats with Save Mesh.
• ExportGeo-CAD saves the created mesh directly to the hard disk. Therefore, it is not possible to edit the mesh after creation.

Since both modules work in a similar way, only MeshGeo is explained in this handbook where it matches the functionality of ExportGeo-CAD.

To access MeshGeo, select Model → MeshGeo in the menu bar:

To access ExportGeo-CAD, select Export → ExportGeo-CAD in the menu bar:

In the MeshGeo or ExportGeo-CAD section, to the left of the Visualization area, a pull-down menu displays the choices for the meshing options. The options available for Create Mesh are the same for both modules.

Additionally, MeshGeo contains options to further edit and save the mesh. For ExportGeo-CAD, the mesh can only be directly saved after the creation. The available options to save the mesh are the same for both modules and explained together in Save Mesh.
