Parameters

geometry

Type: System.Collections.GenericIEnumerableGeometryBase
A combination of curves, brep trims, points, point clouds or meshes. Curves and trims are sampled to get points. Trims are sampled for points and normals.

startingSurface

Type: Rhino.GeometrySurface
A starting surface (can be null).

uSpans

Type: SystemInt32
Number of surface spans used when a plane is fit through points to start in the U direction.

vSpans

Type: SystemInt32
Number of surface spans used when a plane is fit through points to start in the U direction.

trim

Type: SystemBoolean
If true, try to find an outer loop from among the input curves and trim the result to that loop

tangency

Type: SystemBoolean
If true, try to find brep trims in the outer loop of curves and try to fit to the normal direction of the trim's surface at those locations.

pointSpacing

Type: SystemDouble
Basic distance between points sampled from input curves.

flexibility

Type: SystemDouble
Determines the behavior of the surface in areas where its not otherwise controlled by the input. Lower numbers make the surface behave more like a stiff material; higher, less like a stiff material. That is, each span is made to more closely match the spans adjacent to it if there is no input geometry mapping to that area of the surface when the flexibility value is low. The scale is logarithmic. Numbers around 0.001 or 0.1 make the patch pretty stiff and numbers around 10 or 100 make the surface flexible.

surfacePull

Type: SystemDouble
Tends to keep the result surface where it was before the fit in areas where there is on influence from the input geometry

fixEdges

Type: SystemBoolean
Array of four elements. Flags to keep the edges of a starting (untrimmed) surface in place while fitting the interior of the surface. Order of flags is left, bottom, right, top

tolerance

Type: SystemDouble
Tolerance used by input analysis functions for loop finding, trimming, etc.
