Extend 3D Polyline to Surface

This command extends 3D polylines to a surface. The 3D polyline is extended from the selected end of the polyline using the slope of the polyline end segment until this vector intersects the surface. The surface is defined by a 3D grid or triangulated surface model which can be selected from a .grd, .flt or .tin file.
