Creating Sample Points

The tool is invoked by executing the program sj708 from a command prompt and then supplying the following information:

• Full path and filename for the output file

• Path to the folder containing the surface files, dml or dms. ( Not prompted if a project is selected with SB_NAVARCH set or for projects using a NAPA surface)

• Name of the surface

• Limits for the sections and waterlines, AFT, FWD, lower and upper

• Distance between cuts

The fitting of bi-arcs are using the default tolerance for surface intersections, normally set to 0.5 mm.

The sample file below shows an example of a file created by the tool:
