GeometryCreationUtilities.CreateSweptGeometry(CurveLoop, Int32, Double, IList<CurveLoop>) Method

Creates a solid by sweeping one or more closed coplanar curve loops along a path.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 26.4.0.0 (26.4.0.0)

Syntax

C#

public static Solid CreateSweptGeometry(
	CurveLoop sweepPath,
	int pathAttachmentCrvIdx,
	double pathAttachmentParam,
	IList<CurveLoop> profileLoops
)

Parameters

sweepPath CurveLoop

The sweep path, consisting of a set of contiguous curves. The path may be open or closed, but should not otherwise have any self-intersections. The path may be planar or non-planar.

pathAttachmentCrvIdx Int32

The index of the curve in the sweep path where the profile loops are situated. Indexing starts at 0. Together with pathAttachmentParam, this specifies the profile's attachment point.

pathAttachmentParam Double

Parameter of the path curve specified by pathAttachmentCrvIdx. The profile curves must lie in the plane orthogonal to the path at this attachment point.

profileLoops IList<CurveLoop>

The curve loops defining the planar domain to be swept along the path. No conditions are imposed on the orientations of the loops: this function will use copies of the input loops that have been oriented as necessary to conform to Revit's orientation conventions. Restrictions:

The loops must lie in the plane orthogonal to the path at the attachment point as defined above.
The curve loop(s) must be closed and should define a single planar domain (one outer loop and, optionally, one or more inner loops)
The curve loops must be without intersections, self-intersections, or degeneracies.
No loop may contain just one closed curve - split such loops into two or more curves beforehand.

Return Value

Solid
The requested solid.

Exceptions

Exception	Condition
ArgumentException	The input argument sweepPath should at least contain one curve. -or- The input argument pathAttachmentCrvIdx is not valid. The given attachment point doesn't lie in the plane of the Curve Loop. -or- The profile CurveLoops do not satisfy the input requirements.
ArgumentNullException	A non-optional argument was null
InvalidOperationException	Failed to create the swept solid.

Remarks

The profile loops must lie in a plane orthogonal to the sweep path at some attachment point along the path.
