Patch different result Rhino Command and C#

[spb (Steven Burzinski)]

Using CreatePatch in RhinoCommon without a starting surface

The RhinoCommon Patch stuff uses completely different code than the Patch command. But you should be able to produce surfaces that are nearly identical. The function that takes no starting surface makes up a bunch of the detailed arguments. They look reasonable, except that the starting surface pull (see the arguments to the version of CreatePatch that exposes all controls) is set to 1, which makes the plane that gets cooked up have an influence on where the surface goes. If I change that to 0…

Instead of using _Patch’s Stiffness value as an argument for CreatePatch’s flexibility parameter, try the reciprocal.
