BrepCreateFromSweep Method (Curve, IEnumerableCurve, Point3d, Point3d, SweepFrame, Vector3d, Boolean, SweepBlend, SweepMiter, Double, SweepRebuild, Int32, Double, Boolean)

Sweep1 function that fits a surface through a series of profile curves that define the surface cross-sections and one curve that defines a surface edge. Unlike other CreateFromSweep and CreateFromSweepSegmented overrides, this method: - Matches shape curve directions and (for closed shapes) seam points before sweeping, which prevents twisting. - Detects when the inputs qualify for a "simple sweep" and creates a simpler surface in this case. - Lets the caller pick between the refit - rail and segmented sweep paths. - Splits the resulting Breps at fully multiple knots.

Parameters

rail
Type: Rhino.GeometryCurve
Rail to sweep shapes along.
shapes
Type: System.Collections.GenericIEnumerableCurve
Shape curves.
startPoint
Type: Rhino.GeometryPoint3d
Optional starting point of sweep. Use Point3d.Unset if you do not want to include a start point.
endPoint
Type: Rhino.GeometryPoint3d
Optional ending point of sweep. Use Point3d.Unset if you do not want to include an end point.
frameType
Type: Rhino.GeometrySweepFrame
The frame type.
roadlikeNormal
Type: Rhino.GeometryVector3d
The roadlike normal directoion. Use Vector3d.Unset if the frame type is not set to roadlike.
closed
Type: SystemBoolean
Only matters if shapes are closed.
blendType
Type: Rhino.GeometrySweepBlend
The shape blending type.
miterType
Type: Rhino.GeometrySweepMiter
The mitering type.
tolerance
Type: SystemDouble

[Missing <param name="tolerance"/> documentation for "M:Rhino.Geometry.Brep.CreateFromSweep(Rhino.Geometry.Curve,System.Collections.Generic.IEnumerable{Rhino.Geometry.Curve},Rhino.Geometry.Point3d,Rhino.Geometry.Point3d,Rhino.Geometry.SweepFrame,Rhino.Geometry.Vector3d,System.Boolean,Rhino.Geometry.SweepBlend,Rhino.Geometry.SweepMiter,System.Double,Rhino.Geometry.SweepRebuild,System.Int32,System.Double,System.Boolean)"]

rebuildType
Type: Rhino.GeometrySweepRebuild
The rebuild style.
rebuildPointCount
Type: SystemInt32
If rebuild == SweepRebuild.Rebuild, the number of points. Otherwise specify 0.
refitTolerance
Type: SystemDouble
If rebuild == SweepRebuild.Refit, the refit tolerance. Otherwise, specify 0.0.
refitRail
Type: SystemBoolean
false = segmented sweep, true = refit-rail sweep.

Return Value

Type: Brep
Array of Brep sweep results.
Remarks
This version mimics what Rhino's Sweep1 command does.
