To export contour lines: 1. Select the map by clicking on the map in the plot window or by clicking on the map icon in the Object Manager. 2. Choose Map | Contour Map | Export Contours. 3. In the Save As dialog box, type TUTORWS in the File name edit box. 4. Click Save and the file is exported to the current directory.

To change orientation and tilt: 1. Click the wireframe map and selection handles appear surrounding the map. 2. Choose the Map | 3D View command. The View dialog box is displayed. This box allows you to control the tilt, rotation, and projection type for the selected map. 3. Use the Rotation scroll bar to change the rotation to 210°. As you change the rotation angle, the graphic image in the dialog box changes to indicate the orientation. The View dialog box allows control of the tilt angle, rotation angle, and the projection type. Docsity.com Chapter 2 - Surfer Tutorial 27 4. Use the Tilt scroll bar to change the angle to 40°. 5. Click OK in the dialog box and the wireframe map is redrawn at the new orientation and tilt angles. The wireframe map at a new rotation angle and tilt.

In this example, the Z scaling is changed, and the wireframe map becomes somewhat exaggerated in the Z dimension. To change the Z scaling: 1. Click the wireframe map, and selection handles appear surrounding the wireframe. 2. Choose the Map | Scale command to display the Scale dialog box. This allows you to set the scaling in each of the three cardinal dimensions on the selected map. You can set scaling by entering the number of map units per inch, or by entering the length for the map in page coordinates. The Scale dialog box specifies the scaling for the selected map.
