Generation of a TIN following a reference line
Menu: Analyse / Ground and Menu: Module Civil / Surfaces / Contour Tab
To analyze the entire surface of the point cloud, uncheck the Limit by corridor option. The surface of the ground will be analyzed.
A surface can also be modified to follow a corridor. In the Civil module, select the surface and go to "Contour" tab. In the table, right-click in the list of points. The option "Generate from corridor" allows you to select an alignment from the list and specify a left and right offset to determine the new surface contour.
