1. Surfaces and terrain
A surface is a 3D model of the ground built from points and lines. It’s the base for every design, so learn to build it correctly and check it.
- • Build a TIN surface from points
- • Add breaklines and boundaries
- • Display contours and analyse slopes and elevations
- 18 min
2. Alignments
An alignment is the horizontal path of a road, pipe or channel: straights joined by curves, measured by chainage. Learn to lay one out and label it.
- • Create an alignment with the layout tools
- • Understand tangents, curves and spirals
- • Apply design criteria
- 18 min
3. Profiles and vertical design
A profile is the vertical story of an alignment: the existing ground and the designed grade. Learn to create both, and design grades with vertical curves.
- • Create a surface profile and profile view
- • Design a vertical profile with PVIs and curves
- • Understand grades and K values
