Apply scale factor for start station:
If this option is enabled then the starting station will be converted using the scale
factor. For example, a start station of 1000 would become 3280.833. If disabled, the start station would remain at 1000.
If the goal is to change the starting station by a certain amount unrelated to the scale factor, then you must use
Input-Edit Centerline
and enter a new start station in the initial dialog. This will automatically translate all stations in
the centerline by the appropriate amount.
When Apply Scale Factor for start station is enabled, the centerline is adjusted by the scale factor, after a confirming
warning screen.
Profile Conversion
This command converts vertical alignments to and from the profile format (*.PRO). Supported file types include:
 ASCII-LDD (.TXT)
 Caice (.KCP)
 CLIP (.ALZ)
 ISPOL (.RAS)
 LandXML (.XML)
 Leica (.GSI)
 MOSS (.INP)
 SDMS (.PRO)
 SDR (.SDR)
 SMI (.CH)
 TDS (.RD5)
 Terramodel/Geodimeter (.RLN, .ALN and .ARE)
The FAST Survey format has a .PRO extension. These source files can be loaded into FAST Survey using the Data
Transfer
feature in the FILE tab. The conversion screen is similar to Centerline Conversion, with the characteristic
“criss-cross” logic for 2-way conversion (LandXML and Leica) and one-way import only conversion for the other
options.
