# RXL files

RXL files define an alignment and can be used in General Survey or in Roads:

- Alignments in General Survey always have a horizontal component. A vertical component is optional.

- Alignments in Roads, as well as having a horizontal and vertical component, can also include templates, superelevation and widening records, and additional points and strings that define additional components.

If an RXL file contains these additional components, they cannot be staked from the General Survey Stakeout menu. You must use the Roads Stakeout menu to stake out components other than the horizontal or vertical alignment.

A GENIO road file can be used only in Trimble Access Roads.
