Overview
The Reference Line application program can be used to set out or measure points relative
to a reference line or a reference arc.
The Reference Line application program can be used for the following tasks:
•
Measuring to a line/arc where the coordinates of a target point can be calculated from its
position relative to the defined reference line/arc.
•
Staking to a line/arc where the position of a target point is known and instructions to locate
the point are given relative to the reference line/arc.
•
Gridstaking a line/arc where a grid can be staked relative to a reference line/arc.
•
Staking to a polyline. Refer to "42.8 Staking to Polyline".
Other functionality available includes:
•
Offsetting the reference line/arc horizontally or vertically. The radius of the arc changes
with the horizontal offset.
•
Shifting the reference line with parallel offsets or rotating to match predefined setting out
instructions.
•
Measuring points and staking points on slopes related to a reference line/arc.
The Reference Line application program must be activated via a licence key. Refer to "30
Tools...\Licence Keys" for information on how to activate the application program.
