Import DFN

In the Define DFNs dialog, DFN can be imported to RS3. To use the option:

1. Select the Define DFNs option under the Discrete Fracture Networks (DFNs) sub-menu in the Materials menu. You will be prompted to a dialog.
2. In the Define DFNs dialog, select the “…” icon beside the DFN set, and select the Import DFN option from the dropdown menu.
   



3. In the Open dialog, choose the DFN file(s) to import. Supported file formats include *.dwg, *.dxf, *.obj, and *.stl. Click Open when completed.
   • In the Define DFNs dialog, the imported DFN(s) are now added under the DFN set, as shown in the image below. Note that:
   • The imported DFN properties include the filename, joint property.
   • For the Property, you can choose a defined joint from the dropdown menu. You can also use the edit tool to modify existing joints or define new joints.
   • If the imported file contains multiple layers, and the file type is *.dxf or *.dwg, then each layer will be imported as a separate DFN with its own joint property. These new joint properties will be defined as a new joint each, as also listed in the Define Joint Properties dialog.
