4. To set the horizontal offset, press Horizontal Offset. See 5.5.3 Setting horizontal
offset.

To confirm the settings, press \; to exit without saving changes, press =.
The most common lift and offset problem is:
Problem Action
Unable to lift or
drop a layered lift
working surface
The allowable offset direction of a layered lift working surface from a design
surface is determined by the setting of the Side slope:<value> softkey that
appears in the Select Design File dialog when a .dc road design is selected.
For example, if Side slope:Fill is shown, the layered lift working surface must
be below the design surface, and the offset of the layered lift must be
negative.
Note – This restriction does not apply to road files that have been exported
from SiteVision Office to support dynamic layered lifts.
5.5.2 Selecting focus for horizontal guidance
To set or change the focus that is given horizontal guidance:
1. If you have not already done so, select an alignment as described in 5.5.9
Selecting horizontal alignment. Until an alignment is specified, no horizontal
guidance is given.
2. To change the focus point, press either Bucket:Left, Bucket:Center, or
Bucket:Right.
5.5.3 Setting horizontal offset
1. If you have not already done so, select an alignment as described in 5.5.9
Selecting horizontal alignment. Until an alignment is specified, any horizontal
offset has no effect.
2. From any of the guidance views, press Offsets. For a list of softkey icons and
their functions, see Softkeys, page 27.
The example below shows the Horizontal Offset dialog when a road alignment
has been chosen for horizontal guidance.
