Web30 apr. 2024 · 7.4: Horizontal Curves. Horizontal Curves are one of the two important transition elements in geometric design for highways (along with Vertical Curves). A horizontal curve provides a transition between two tangent strips of roadway, allowing a vehicle to negotiate a turn at a gradual rate rather than a sharp cut. Web7 apr. 2024 · The Mid-ordinate Distance setting is present when adding boundaries, breaklines, and contours. This setting causes AutoCAD Civil 3D to place supplementary TIN points along the arc. The result of adding data to a surface is a TIN (triangulated irregular network). Triangles have flat edges, not curved.
