Modify Height

Description

Modify a vertices height using the specified method and optionally insert vertices into a line, alignment or polygon.

Access

Home / Tools / Modify / Height

Requirements

Controls

The controls available will depend on the height method selected.

Control	Description
Height Method	Select one of the following methods to input a height for the selected vertices: Default Height Height Height Difference Terrain Model
Vertex	Input the vertex to modify. If an object or objects are currently selected in the model view, this control is disabled.
Insert vertices at terrain model face edges	Do one of the following: Select the checkbox to insert vertices into selected lines, alignments or polygons where they intersect with the terrain model face edges. The vertices heights are interpolated from the terrain model. Clear the checkbox to only modify the heights of the selected vertices. Note: This control is available when the Height Method is configured to Terrain Model. Selecting the checkbox will insert vertices for all selected objects, regardless of if the existing vertices in the line are modified. Vertices are inserted into straight segments only.
Update vertices with non-default heights	Do one of the following: Select the checkbox to modify the heights of all selected vertices. Clear the checkbox to only modify the heights of the selected vertices which have a default height.

Notes

You can use the Modify Height tool:
- for objects selected in the model view. Click OK to modify the height.
- by keying in a vertex. Click OK to modify the height.
- by picking a single vertex from the model view. The height is updated instantaneously.
If modifying the height of vertices will break the geometry of any objects, no modification is made to any of the selected vertices.
Vertices with default heights that overlap the terrain model can have new heights interpolated.
To modify the heights of vertices in a point cloud, use the Modify Shift tool.
