Create geometry / From line string
Create geometry / From line string command generates a preliminary vertical geometry. It uses only the filtered survey vector element as basis for computing the vertical geometry components.
To generate vertical geometry directly from the filtered survey line string:
1. Select the filtered survey vector element using CAD Selection tool.
2. Select Create geometry / From line string command from the Vertical pulldown menu.
This opens the Create vertical geometry components dialog:
3. Define settings and click OK.
This starts the automatic process for generating the preliminary geometry.
4. Place the frame for displaying the profile of the vertical geometry components by a data click inside a CAD view.
The elements drawn in the profile frame have station and elevation values scaled as specified in the Component fitting / Profile category of TerraScan Settings. The frame is drawn on the level defined in the Component fitting / Levels category of TerraScan Settings.

EFFECT |
|---|---|
Min. component length |
The application attempts to generate a geometry that has components longer than this value. Usually, the components are much longer and this value only comes into effect in extreme cases. |
Maximum residual |
Determines the goal for the level of agreement between the generated geometry and the vertices of the line string. In other words, the application adds components or continues to try to converge the components until this level of agreement is reached. Typically, the maximum residual that can be achieved for the vertical geometry is smaller than for the horizontal geometry. |
