Construct lines

Use the line tool   to place horizontal construction lines.


After design settings and contour map parameters are set, we are ready to place construction line for the roadway geometry design. Click on the  icon from the toolbar and move the mouse to a desired starting point (for example, point A on the map). Click on the left mouse and drag it to a desired end location. A line (linear roadway) will be drawn when dragging the mouse on the map. A horizontal construction line will be plotted when releasing the left mouse button. For this tutorial, please construct three lines from point A to point B on the map as shown in Figure 3.

Note: Use right mouse clicking on a segment (line or curve) to delete.
