Tessellated |
Builds a mesh by extruding curve loop(s) along extrusion distance.
Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax
public static MeshFromGeometryOperationResult CreateMeshByExtrusion( IList<CurveLoop> profileLoops, XYZ extrusionDirection, double extrusionDistance, ElementId materialId )
Public Shared Function CreateMeshByExtrusion ( profileLoops As IList(Of CurveLoop), extrusionDirection As XYZ, extrusionDistance As Double, materialId As ElementId ) As MeshFromGeometryOperationResult
public: static MeshFromGeometryOperationResult^ CreateMeshByExtrusion( IList<CurveLoop^>^ profileLoops, XYZ^ extrusionDirection, double extrusionDistance, ElementId^ materialId )
static member CreateMeshByExtrusion : profileLoops : IList<CurveLoop> * extrusionDirection : XYZ * extrusionDistance : float * materialId : ElementId -> MeshFromGeometryOperationResult
Parameters
- profileLoops IListCurveLoop
- The profile loops to be extruded. The loops will not be modified.
- extrusionDirection XYZ
- Direction of extrusion. The length of this vector is ignored.
- extrusionDistance Double
- The positive distance by which the loops are extruded in the direction of the input extrusionDir.
- materialId ElementId
- Material which should be used by a constructed mesh.
Return Value
MeshFromGeometryOperationResultReturns a mesh, which was constructed, and some additional information.

Exception | Condition |
---|---|
ArgumentException | The input value cannot be used as thickness for an extrusion, or blend, or wall layer, or similar geometric construct. |
ArgumentNullException | A non-optional argument was null |
ArgumentOutOfRangeException | extrusionDirection has zero length. |

This function supports creation of a mesh given a collection
of continuous curve loops, which are processed independently
from each other. Loops with gaps or with curves with
wrong flips will be split before processing.
