Fairing

As an alternative to fairing by the traditional method, 3D fairing is achieved by using a minimal amount of data, that means, profile curves, some control curves and a preliminary set of sections. The hullform defined by the foregoing data is examined to determine regions of inflection or similar curvature , and construction lines (CLINES) are created in these areas. Knuckles, Tangent or Pline curves can then be created by projecting the Clines onto selected orthogonal curves. The angle curves associated with knuckle and tangent curves are then created. The original orthogonal curves can be switched off and new orthogonal curves generated from the 3D curve are used to check the fairness while all fairing is done using the 3D curves alone.
