In the 3D viewer, the design data is shown in its original position. The point to
stake symbol is shown in its shifted position.
The sign convention for design shifts is identical to the convention used for
stake offset and height difference.

Road_053
Horizontal stake offsets are always defined perpendicular to the centreline of
the layer the line/s belongs to.

b
Road_010
The shifts applied to lines, slopes, road crowns layers and DTMs are identical
with one exception: Given that DTMs are not defined relative to a centreline
and hold no orientation information, no horizontal shift is possible for a DTM.

Description
Before/after the defined shift range, no shift
is added. Outside of the defined shift area
the original design is used. This option
means a "step" appears at the start and/or
end of the shifted area.
