Slope

Module(s): Digital Terrain Model

You can use the Slope tool to draw slopes by entering the outline of the area to slope, or the edge of the slope and then its angle. You can define sloping areas with different angles of inclination.

To apply a slope

1. Click Slope (How).
   

   Activate Slope in one of the following ways

   • Menu bar: Modify Terrain Digital Terrain Model

   • Palette: Tools Change area in the following module(s):

   Digital Terrain Model

   • Configuration: Landscaping/Urban Planning Digital Terrain Model flyout
2. Click the DTM in which the slope is to be drawn.
3. In the input options, click Surfac to enter the surface outline of the slope or Edge to enter the edge of the slope.
4. Enter the height of the horizon for the edge of the slope (does not apply in Surfac mode).
5. On the context toolbar, enter settings for the slope.
6. Enter the area to which the slope defined on the Context toolbar is to be applied.
   If you confirm the default, the slope is created using the set value.
7. If you want to create several sloping areas with different angles, specify in the input options whether the change in angle is to be abrupt (Skew set to off) or not.

Example of slope

Beispiel für allgemeines Böschen

	A Skew B Surface of slope C Calculated section polygon

to point 1: Inclination 1:1
to point 2: Inclination 1:3 with skew
to point 3: Inclination 1:2 with skew
to point 4: Inclination 1:2
to point 5: Inclination 1:1

Note: You can specify whether the slope area and slope edge are created as polygons in the Options.

Note: After applying this slope, the mesh of the original model is retained up to the slope edges, so that there are not any cutaways that might falsify the cut and fill calculation. However, if you optimize the grid with Mesh, Optimize Grid, this effect no longer applies.
