Modifying the height of terrain points

Module(s): Site Plan

You can use the Modify Terrain Point Height tool to modify the height of terrain points - for example, to modify the point symbols on an element so that they automatically adjust to a gradient drawn in 2D. The only requirement is that the terrain points must exist as 3D symbols.

To modify the height of terrain points

1. Click Modify Terrain Point Height (How).
   

   Activate Modify Terrain Point Height in one of the following ways

   • Menu bar: Modify Terrain Site Plan

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

   Site Plan

   • Configuration: Landscaping/Urban Planning Site Plan flyout
2. You can use the Input Options to specify whether you want to use the terrain points on the Selected element in its entirety or on a Part of the selected element.
3. Click the element on which the terrain points are located. When set to Part of selected element, specify the section by clicking the start and end points.
   The start point is indicated by a small direction arrow.
   

   • Click the point.
   • Align to points using the linear snap function and click the point.
   • Define the point by making entries in the dialog line.

   Tip: To find out how to enter points in Allplan, see Precision Drawing.

   Tip: The shortcut menu and dialog line provide tools and options to assist you in the process of entering points. For more information, see Tools and Options.

   Note: When you click points outside the element, the points on the element that are perpendicular to the points you clicked are used.

4. Enter a scale factor In the Input Options.
5. Click the element (the gradient) whose height values you want to adopt.
6. Enter the height in the reference point or click a point whose height you want to use.

Example of adopting the terrain point height

Example of adopting the terrain point height

Gradient A Start B End C Reference height D X axis = 5.97 m E New heights Element with terrain points A Start B End F Initial heights G Arc = 5.97 m

Note: The element’s arc length and the X axis of the gradient must have the same length. Otherwise, only the points that can actually be counted as part of the gradient are calculated.
