How to define a terrain gradient

In this Video-Tutorial we show you, how you can define a terrain gradient.

The basic workflow:

  • In the first step we select in the 2D view and the 3D view the layer “Environment”.
  • Please note that all terrain points and terrain lines have to be inside the terrain frame (with a minimum distance from 1m to the border of the terrain frame) of the 2D view. If our terrain gradient gets larger than the environment, we select the environment – right mouse button – “Properties”. Here we can define the dimensions (width & depth) of the environment and we can also change the appearance of the environment.
  • To define the terrain gradient we recommend the help of guidelines (“2D & Layout” – “2D Guidelines” – “Guideline”).
  • Before we enter the height contours we have to change, if necessary, the absolute level of the environment. Therefore we make a right mouse click on the layer “Environment” – “Properties”. At the Point “Absolute level” we enter the lowest point of our future terrain and after it we press “Ok”.
  • To enter a height contour we select “Terrain” – “Terrain contour” – “Enter height contour”.
    Please note that two height contours never should cross each other. If they meet in edge points they MUST have the same worth. We enter the high contour along our guideline in the 2D view. After it we press the right mouse button and select “Complete”. After it the window “Height contour” opens and there we define the height for every point of our height contour. For the point “Segments” we recommend to enter “3”. After the entry of the height contours we press “ESC”.
  • To open and edit the Properties of a height contour we select a height contour – right mouse button – “Properties”.
  • If we like to define a ridge or an immersion inside the terrain surface we recommend to define also the laterally height contour.
