Creating contour lines for a terrain model

Contour lines represent the elevation and shape of the terrain, providing valuable information for analysis and design. Pythagoras CAD software simplifies this process with its intuitive tools. This article will walk you through the steps to create contour lines for a terrain model, ensuring accuracy and efficiency.

Creating contour lines

STEPS

Have your terrain model file ready for use.

Select the menu DTM > Contour lines.

In the Contour Lines window

• Choose the graphical display for the contour lines (color, thickness, line style) (1).
• Enter the value for the height difference (interval) between the contour lines (2). Check the box Automatic adjust Elevations to adjust the initial and final elevation to the specified interval.
• Enter the start and end height (3). To display the contour lines in real numbers, round the heights based on the calculated height information displayed on the left side.
• Enter a layer name (4). The layer can be created 'on the fly' by entering the name here for the first time.

Click OK to generate the contour lines based on the configured settings.
