Similar to a 2D Topographical plan, the 3D plan includes an additional (Z) coordinate for the surveyed detail points. All 3D Topographical plans are created using 3D polylines.
The contour lines displayed on the drawing plans will help you to determine the terrain slope and ground configuration. Features represented on these types of drawing plans are drawn to scale and are related to the real-world position.
We are flexible and we can tailor the survey to fit your requirements!
