Command line options can be specified for INC2APT configurations in the SURFCAM.PST file. Normally INC2APT is executed as part of a post command sequence. The default configuration provides the input and output file names only and uses all the default options.
The Decimal and Vector Precision are stored in and recovered from the registry, so they do not have to be specified every time. If you wish to change the default values, you may run INC2APT from the command line (or explorer) once so the dialog box is displayed to set the desired output precision.
Refer to Convert INC to APT for the command line options.
