Add a Terrain

You can add a terrain by selecting the corner points of the lot and other terrain points and/or elevation curves. You can select any points from the drawing as terrain points. If you wish to add a terrain by selecting elevation curves, first draw the lines depicting the elevation curves in the drawing, see Preparations. You can select the terrain properties when adding the terrain, or later when editing the terrain.

1. Select Modeling | Zone | Add Terrain.

   The Terrain Properties dialog box opens.

2. Select the method for defining the height of the points. In the drawing, you can define the height according to either absolute or relative height system. In the absolute system, the height is measured in relation to the sea level. This requires that the building’s height data - site height, site height from model origin and building height from model origin - have been set, see Building Coordinates and Heights. The building height calculated according to the given height data is displayed in the Base z-height [m] field. If the height data has not been set, the systems do not differ from each other.
   • Digitized - Click the points in the model.
   • Absolute - Enter the height of the terrain point in relation to the sea level, and click a point in the drawing.
   • Relative - Enter the height of the terrain point in relation to the model's origin, and click a point in the drawing.
