CreateExtrusionGeometry Method (IList(CurveLoop), XYZ, Double)

Creates a solid by linearly extruding one or more closed coplanar curve loops.

Namespace: Autodesk.Revit.DB

Syntax

C# 
public static Solid CreateExtrusionGeometry(
	IList<CurveLoop> profileLoops,
	XYZ extrusionDir,

Public Shared Function CreateExtrusionGeometry ( _
	profileLoops As IList(Of CurveLoop), _
	extrusionDir As XYZ, _
	extrusionDist As Double _
) As Solid
Visual C++ 
public:

	IList<CurveLoop^>^ profileLoops, 
	XYZ^ extrusionDir, 
	double extrusionDist
)

Parameters

profileLoops
Type: System.Collections.Generic IList CurveLoop
The profile loops to be extruded. The loops must be closed, coplanar, and without intersections, self-intersections, or degeneracies. No loop may contain just one closed curve - split such loops into two or more curves beforehand. 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.
extrusionDir
Type: Autodesk.Revit.DB XYZ
The direction in which to extrude the profile loops. This vector must be non-zero and transverse (i.e., not parallel) to the plane of the profile loops. Its length is irrelevant; only its direction is used.
extrusionDist
Type: System Double
The positive distance by which the loops are to be extruded in the direction of the input extrusionDir.

Return Value

The requested solid.

Exceptions

Exception Condition
Autodesk.Revit.Exceptions ArgumentException The profile CurveLoops do not satisfy the input requirements. -or- The Input extrusionDir must be a non-zero vector. The normal of the loop plane should not be perpendicular to the given extrusionDir. -or- The input argument extrusionDist must be positive.
Autodesk.Revit.Exceptions ArgumentNullException A non-optional argument was NULL
