Fieldbook formats

.fbk is the default internal file format for raw survey data. we can use 2 different dataformats as raw data

1: Raw data based on horizontal angle, vertical angle ,vertical distance and description code

If you don’t use any figure command the software recognizes the surveyed point as a point,
If you use only the figure start command all the surveyed points are recognized as straight lines till the figure end command.

Trimble can save the raw data directly into .fbk file format from the datalogger
Leica can save the raw data directly into .fbk format form Leica Geo office as desktop solution
Stringer connect can convert from a variety of raw data formats into .fbk as a desktop solution
Carlson connect can convert form a variety of raw data formats info .fbk as a pulldown menu in Civil3D

Point label description key set

When you import the .fbk file in your survey database Civil3d recognizes the survey points as cogopoints. The representation of the cogopoints are manageable in the description key set
Just a little knowledge update

We can use the key set as a hard coded point label

View image

The label manageable by the point label style gives always the value set by the description key format tab
The point graphical representation is manageable by the point style

Or as flexible coded point label

View image

The label manageable by the point label style gives always the value set by the description key format tab
$* is the complete raw description key, $1 the first part of the description key, $2 the second… the rest of the $ options is findable in the well documented help file.
The flexible coded point label makes it possible to fulfil any customer point label demand

more to come.... Chris Berends
