+Production of the DAGMC Geometry: Coreform Native Export
+--------------------------------------------------------
+
+As of version 2023.8, Coreform Cubit has a native DAGMC export capability. This
+requires that the model is meshed either with the tetmesh or trimesh schemes
+(i.e. that surfaces of the model have triangles associated with them to be
+exported.) Faceting/meshing parameters are absent from this command as they are
+supplied to the meshing schemes mentioned previously. The export command is as
+follows:
+

+    CUBIT> export cf_dagmc <filename> [overwrite]
