      I have a set of offsets I would like to import. But the data is in the form of x,y,z co-ordinates for the chines and deck line at each station – not the positions of the waterlines.

      Can I import this data?

      • The first line of the file must either be a 0 (zero) or a 1. A zero indicates that all coordinates are in meters while a one indicates that the coordinates are in feet. Each chine is defined by a sequence of X,Y and Z coordinates (all on the same line and separated by a space). Make sure you use a period to separate the decimals, not a comma!. The end of each chine is indicated by a new empty line after the last coordinate. The last line in the file should be ‘EOF’.
      • The number of points is allowed to differ from chine to chine.
      • The curves are imported and the chines are fitted to the datapoints of each imported curve in such a way that the chines from the imported hull match these curves. The imported curves are also added to the model as markers.
      • The chines must be ordered from the bottom up with coordinates going from aft to front. At least three curves must be in the file: The keel line, at least one chine and finally the deck- or sheerline. Controlcurves are added to the crease edges corresponding to each chine.

      For example:
