- Click Home | Grid Data | Grid Data.
- Click Open Data dialog, select the DXF file in the Open worksheets field and then click Open.
- In the Grid Data dialog, adjust the gridding parameters as desired and then click OK.
- Click OK in the Surfer dialog indicating that the grid was created.
- Click Home | New Map | Contour.
