Translations:Macro Half-Hull Model/91/en

- this is just at the idea stage but would give a much smoother surface in the vertical dimension, however the horizontal surface would still be faceted as it is now) - an initial goal, but the feasibility has not been investigated
 * replace line segments of cross-sections with curved lines
 * integrate with Draft workbench to produce drawings from models
 * handle keels, skegs and rudders- one work around for keels with the present system is to model the keel as a half-hull on it's own and then assemble it onto the bottom of the main hull; this would still do nothing for rudders and skegs though
