There are many import routines available under Centerline
Conversion to convert other applications' centerline files to
Carlson centerline files (.CL), and many export routines to convert
Carlson centerline files (.CL) to other applications'
formats. Each Import option prompts for the file to convert
and the name of the new .CL file to create. Each Export option
prompts for .CL file to convert and a file name for the new file.
The import formats include C&G Point Group .PTS, InRoads .ASC,
Geodimeter .ARE/.GEO/.RAW, GeoPak .OSD, Leica .GSI, MOSS .INP,
Novapoint .TIT, SDMS .ALI/.PRJ, Softdesk, Sokkia .SDR, ISPOL .ALI,
CLIP .PLA, TDS .RD5 and Terramodel .RLN/.ALN. The export formats
include C&G Point Group .PTS, Leica .GSI, SMI .CH, Softdesk,
Sokkia .SDR, Topcon .RD3, Trimble .DC, TDS .RD5 and TDS
.PL5.
For the TDS RD5, there is an option to include a profile along
with the centerline. Also, there is an option to include sections.
When sections are included, the station data is included in the RD5
and the section grades are output to TP5 files where each station
has a separate file for the left and right sides. The TP5 files are
created in the same folder as the RD5.
For the Trimble DC, there are options to include a profile and
sections along with the centerline.
For Civil 3D, the import works differently because the
centerline definitions are stored within the drawing instead of
external file. So this import does not prompt for a file but looks
for Civil 3D centerlines in the current drawing. The Civil 3D
centerline custom objects are converted to standard AutoCAD
entities and there are prompts to save the centerline definitions
to Carlson .CL files.
