To key in an alignment
In Trimble Access, an alignment is a polyline. Alignments are saved as RXL files.
Alignments defined in General Survey always have a horizontal component that consists of straight lines, and optionally circular arcs. A vertical component is optional and consists of grades between points.
If you have the Roads software installed, you can include templates and superelevation and widening records when you create or edit a road.
To create an alignment:
- To open the Key in alignment screen, do one of the following:
Tap
and select Key in / Alignments.
If the Select an alignment screen appears, select the alignment from which to create a new alignment, or tap New. If the Select an alignment screen is not visible and you want to select an alignment, tap Select.
- In the map, select the points, lines, arcs, or alignments from which to create a new alignment. From the tap and hold menu, select Key in alignment.
