This node generates a NURBS Surface object from several NURBS or NURBS-like Curves by applying so-called "skinning", or "lofting", operation. In a way, "lofting" is interpolation of several curves to make a surface. So, this node is somewhat similar to "Surface from Curves" node. Differences are:
- "NURBS Loft" can work only with NURBS and NURBS-like curves, while "Surface from Curves" works with arbitrary (e.g. formula-specified) curves.
- "NURBS Loft" node always generates a NURBS Surface; for such surface, some specific API methods can be applied; such surface can be saved in some file format, which understands only NURBS (at the moment, see "NURBS to JSON" node; later, nodes to save NURBS in some industry-used formats can appear).
- "NURBS Loft" usually works a lot faster comparing to "Surface from Curves".
At the moment, this node can effectively work with the following types of curves:
- NURBS curves
- Bezier curves
- Cubic splines
- Polylines
- Circular arcs
- Line segments
Some nodes, that output complex curves composed from simple curves (for example, "Rounded rectangle"), have NURBS output parameter; when it is checked, such nodes output NURBS curves, so "NURBS Loft" can work with them.
