5.5.1.3 2D / 3D object proximity alarm
When using the “proximity alarm”, the system gives warning when measurement point of the
bucket is closer to object than pre-defined value. Object is a line or a point.
The proximity alarm can be used with
• LandXML
• DXF
Take proximity alarm to use by adding “ !W=X ” to a file name, “X” stands for a warning distance
given in centimetres.
Example of the proximity alarm of one meter (100 cm) :
Rename file “Road_one .xml” to “Road_one !W=100 .xml”.
The system gives warning with 2D or 3D objects just depending on the Z coordinate of the object.
If the Z coordinate is zero then the functionality is automatically in 2D mode.
With 3D objects the alarm can be used for avoiding damaging existing pipes or cables, for
example.
Fig. 70 displays a 3D warning level when working near an existing heating network. Warning level
is set to 100 (equals 100 centimetres).
NOTE! In reality, as small as one metre warning level should not be used due possible damage
for cables or pipelines. Needed warning distance depends on numerous things (accuracy of the
map, is cable still at place where it was placed, and so on)
