A version of Patch which creates a curve rather than a surface from a set of input points is needed. It should have the ability to accept a “starting” curve directly analogous to the use of a “starting” surface in Patch.
One use of this tool would be to create curves from scanned points sets. For example I need to create boundary curves and section curves from point clouds of boat hulls. The boundary curves are then used as input in creating surface models, using Patch with a starting surface and Preserve edges option, or Patch with a set of boundary curves and Automatic trim option, or by using Sweep, NetworkSrf with the curves as input.
