Creating a Terrain Cut

To create a Terrain Cut you must first import a data source containing elevation data, see Importing a simple data source for more information.

To create a Terrain Cut:

Set the map to the position and zoom level you require.
Click the button on the toolbar and then click the map and draw a line that represents the origin and end of the first part of the polyline you want to draw.
Click the mouse button to create a point and start the second part of the polyline, then click again to create a third part and so on. Double-click to end the polyline.

A Line of View pane is displayed below the map in the Map Builder main window and a Terrain Cut layer is added to the Map Layers pane.
To reposition the polyline, click to select it and drag the whole line as a unit to the new position. The Line of View is automatically updated.
To change the shape of the polyline, click to select it and drag the chosen point to the new position. The Line of View is automatically updated.
To add a point to the polyline, place the mouse pointer on the part of the line where you want to add the point, press CTRL and click. A new point is added to the polyline.
To remove a point from the polyline, place the mouse pointer on the point you want to remove, press CTRL and click. The point is removed from the polyline.
To delete the Terrain Cut layer you can perform one of the following actions:
1. Select the Terrain Cut in the Map Layers pane and press the Delete key on your keyboard.
2. Select the Terrain Cut in the Map Layers pane, right-click and select Delete Layer from the pop-up menu.
