Creates a solid by sweeping one or more closed coplanar curve loops along a path while keeping the
profile plane oriented so that a line in the plane that is initially perpendicular to a given fixed
direction remains perpendicular as the profile is swept along the path.

Parameters
- sweepPath
- Type: Autodesk.Revit.DB..::..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.
With the exception of path curves that lie in a plane parallel to %fixedReferenceDirection%,
the curve's tangent should be nowhere parallel to %fixedReferenceDirection%. If the sweep path
has corners, the solid segments that meet at a corner may not meet smoothly.
- pathAttachmentCrvIdx
- Type: System..::..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
- Type: System..::..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
- Type: System.Collections.Generic..::..IList<(Of <(<'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.
- fixedReferenceDirection
- Type: Autodesk.Revit.DB..::..XYZ
A unit vector specifying the fixed direction used to control how the profile plane is swept along the path; see the description and remarks above.
Return Value
The requested solid.
