This function lets you construct a terrain section without a terrain model. The function is based on the intersection with lines in the drawing.
MOUS_ICO Menu: Landscape > Terrain design > Construct Section
MOUS_ICO Toolbar: Terrain design: Construct Section
Define the intersections with the profile line and a dialog with all intersections comes up.
You can then type in the z-value for each intersection. If you snap to intersect with an object with elevation, the height of the object will come up automatically in the dialog. The figures below show the profile line with all the intersections and the terrain section generated based on the entered heights.
It is also possible to edit a section. Point at the section and then start the function again. The function will then give you the dialog for the existing section.
