Terrain Modeling

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 Terrain > Add Terrain.
2. Select Add points from the auxiliary menu. The function is enabled as a default.
3. Select terrain properties by using the Terrain Properties function on the contextual toolbar.

4. Do either of the following:
   • Select terrain points.
     1. Select Selecting of points from the contextual toolbar.
     2. Select the height definition method from the contextual toolbar:
        • Absolute Z-Height - Specify a point's height in relation to the absolute zero level.
        • Relative Z-Height - Specify a point's height in relation to the terrain's base Z-height.

        Example of Defining Point Heights

     3. Enter the height of the terrain point in the z field in the contextual toolbar.
        

        Enter the height in meters. If you are using the Imperial system, enter the height in inches.

     4. Select a point in the drawing. Select, for example, a corner point of the lot.
     5. If necessary, enter a new height and select a point.

     

   • Select elevation curves.
     1. Select Selecting of lines from the contextual toolbar.
     2. Select the height definition method from the contextual toolbar:
        • Absolute Z-Height - Specify a curve's height in relation to the absolute zero level.
        • Relative Z-Height - Specify a curve's height in relation to the terrain's base Z-height.

        Example of Defining Point Heights

     3. Enter the height of the elevation curve in the z field in the contextual toolbar.
        

        Enter the height in meters. If you are using the Imperial system, enter the height in inches.

     4. Select a line in the drawing.
     5. If necessary, enter a new height and select a line.

     

   By switching the selection method, you can alternatively select either points or lines in the drawing. First select the selection method and then enter the height in the z field.

   

5. Select Confirm. The terrain is modeled in the model window.

   

Note

• You can set the terrain's base Z-height in the terrain properties.
