Stake Spiral and Offset
6WDNHRXW 6SLUDO DQG 2IIVHW
The Stake Spiral and Offset screen allows you to stake stations at
fixed intervals on a spiral curve, or at an offset to it.
Start Point
: is the point associated with the beginning of
the spiral curve. This can either be the TS or the CS,
which is specified later in this screen (see below).
7DQJHQW $]P | 7DQJHQW %HDULQJ : defines the tangent
azimuth or bearing at the entrance to the spiral
5DGLXV | 'HJUHH $UF | 'HJUHH &KRUG : defines the
radius, degree arc, or degree chord of the curve,
respectively.
Length
: is the length of the spiral curve.
Begin Station
: is the station associated with the
Start
Point
.
Turn
: defines if the curve turns toward the
Left
or
Right
from the point of view of the
Start Point
.
Spiral
: defines the direction of the spiral curve by the following
options:
•
TS to SC
: the spiral begins at the tangent (Tangent to Spiral)
and ends at the circular curve (Spiral to Curve).
•
CS to ST
: the spiral begins at the circular curve (Curve to
Spiral) and ends at the tangent (Spiral to Tangent).
