M_Rhino_Geometry_Brep_CreateFromLoft - mcneel/rhinocommon-api-docs GitHub Wiki
Constructs one or more Breps by lofting through a set of curves.
Namespace: Rhino.Geometry
Assembly: RhinoCommon (in RhinoCommon.dll) Version: Rhino 6.0
C#
public static Brep[] CreateFromLoft(
IEnumerable<Curve> curves,
Point3d start,
Point3d end,
LoftType loftType,
bool closed
)VB
Public Shared Function CreateFromLoft (
curves As IEnumerable(Of Curve),
start As Point3d,
end As Point3d,
loftType As LoftType,
closed As Boolean
) As Brep()
- curves
- Type: System.Collections.Generic.IEnumerable(Curve)
The curves to loft through. This function will not perform any curve sorting. You must pass in curves in the order you want them lofted. This function will not adjust the directions of open curves. Use Curve.DoDirectionsMatch and Curve.Reverse to adjust the directions of open curves. This function will not adjust the seams of closed curves. Use Curve.ChangeClosedCurveSeam to adjust the seam of closed curves. - start
- Type: Rhino.Geometry.Point3d
Optional starting point of loft. Use Point3d.Unset if you do not want to include a start point. - end
- Type: Rhino.Geometry.Point3d
Optional ending point of loft. Use Point3d.Unset if you do not want to include an end point. - loftType
- Type: Rhino.Geometry.LoftType
type of loft to perform. - closed
- Type: System.Boolean
true if the last curve in this loft should be connected back to the first one.
Type: Brep[]
Constructs a closed surface, continuing the surface past the last curve around to the first curve. Available when you have selected three shape curves.
