Stake Out Alignments
tween generated points on circular and
spiral horizontal sections. The genera-
tion principle is the same as noted for
Line Stake Interval
.
o Max Line Offset
— if this option is en-
abled (checked), its value controls gen-
eration of additional stakes so that on
curve horizontal sections, deviation of
polyline passing through stakes from
initial curve is within this limit. Algo-
rithm: each generated pair of neighbor
design points is checked for distance
from the ideal curve, and addition-
al stake is inserted between them if
straight line connecting them is more
than Max Line Offset from the curve;
repeated until all connecting lines are
close enough to the curve. Thus, the less
the radius of curvature, the more dense
are generated stakes.
As an example, compare two illus-
trations below: in both cases, Line
and Curve Stake Intervals are set
to 10000 m.
The first one with Max Line Offset
disabled is shown in The second —
with Max Line Offset set to 0.05 m is
shown in Max Line V. Offset — the
same as Max Line Offset, but for par-
abolic curves in vertical alignment...

The second — with
Max Line Offset
set to 0.05 m is shown in Max Line V.
Offset — the same as Max Line Off-
set, but for parabolic curves in verti-
cal alignment..

o Max Line V. Offset
