Translations:Part Loft Technical Details/17/en

The main point

 * The loft is doing B-spline interpolation between the provided profiles. The interpolation is switched to piecewise linear when "Ruled" property is set to true.
 * When number of profiles exceeds 9, interpolation degree is dropped to 3. This switchover can substantially reduce wiggling.
 * Matching the number of segments (aka number of vertices) in the profiles allows one to give the loft a slight twist, and typically permits using more complex profiles.
 * When numbers of segments are not matched, it's best to keep the profiles to be representable by a proper r(phi) function in polar coordinates.
