5.4 Lane guidance
When lane guidance is selected, the machine is guided vertically to the surface of
the specified lane, extended 1 km right and 1 km left of the defined lane limits.
The two main ways to use lane guidance are:
l to hold the machine guidance point onto a specified surface or lane
l to extend a lane sideways, which allows you to deliberately or temporarily get
extended guidance
To use lane guidance:
l the loaded design must be an SVD design with an accompanying SVL file
l a master alignment is required:
If the current design does NOT include a master alignment, you must
select a master alignment before you can select a lane.
If a master alignment is included in the current design, that master
alignment is automatically selected.
Tip – A master alignment can be included in an SVL/SVD design by using Trimble Business
Center – HCE software in the office.
When using Cut/Fill mapping/recording with lane guidance, no updates occur when
a lane is changed and the Cut/Fill mapping/recording must be reset.
If the map is not reset and the guidance point passes over the same area again, the
Cut/Fill color coding is updated with respect to the current design surface.
