Description:

Drape Geometry drapes geometry from an overlay onto the selected TIN item.

For each item in the chosen overlay, each vertex is moved up or down onto the TIN item. Also, whenever a geometry segment crosses a TIN triangle, a 3D vertex is added to the new LineString item, which is on the edge of the triangle.

Each overlay item must be totally inside the TIN item to be modified, since the height outside the TIN item is undefined.
