Stake intersection point
This menu function is available for staking a line with Show information to
an additional line checked in Define Line
The additional line must be a Straight.
Offsets for the selected line and the additional line can be defined.
The menu function Stake intersection point is only available if the
☞
offsets are defined perpendicular to the selected line. Use non-per-
pendicular offset must not be checked.
Stake intersection point is commonly used to stake out bridge abutment
positions. The graphic shows an example.

The calculation of the intersection point is based on:
A perpendicular offset from the selected line, for example bridge centreline
•
A perpendicular offset from the additional line
•
Step-by-step
1.
Define Line
Select the line to work with (bridge centreline) and select a second
intersecting line (abutment centreline) under Show information to
an additional line.
2.
Stake Line,
If necessary, check Use offsets. Type in the offset of the intersec-
tion point in relation to selected line (bridge centreline).
After initialisation
This panel shows the projection
after the reinitialisation.
