Alignments, profiles and cross sections
Centrelines with stationing, existing ground and design profiles, and sections across them.
5 min read
Alignments
- Tangent and curve geometry, entered or drawn.
- Stationing along the whole run.
- Station and offset from any picked point, the everyday question on a linear job.
Profiles
- Pick the alignment and the surface for existing ground.
- Sample it: the surface's elevation along the centreline, at your interval.
- Add a design profile, grades and vertical curves, over the top.
- Read the difference between them at any station.
Cross sections
- Place sample lines across the alignment, at an interval or where you want them.
- Cut sections against the surfaces.
- Read end areas, and volumes between stations from them.

- Volumes: against a datum and between two surfacesExact prismatic volumes, with the method and the area stated so the number can be checked.
- Building a surfaceTriangulate points into ground you can contour, measure and stake from.
- Construction layout and cut sheetsStakeout points and a cut sheet the crew can work from.
