BRep Builder Add Loop Method

Creates an empty loop in a given face of the geometry being built. Other BRepBuilder methods are used to add co-edges to the loop.

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)

Syntax

C++

public BRepBuilderGeometryId AddLoop(
	BRepBuilderGeometryId faceId
)

Public Function AddLoop ( 
	faceId As BRepBuilderGeometryId
) As BRepBuilderGeometryId

public:
BRepBuilderGeometryId^ AddLoop(
	BRepBuilderGeometryId^ faceId
)

member AddLoop : 
        faceId : BRepBuilderGeometryId -> BRepBuilderGeometryId

Parameters

faceId BRepBuilderGeometryId: Id of the face to which the loop should be added. faceId was returned by a call to AddFace().

Return Value

BRepBuilderGeometryId
An id that can be used to identify the loop while the BRepBuilder is actively building geometry (e.g., to add co-edges to the loop).

Exceptions

Exception	Condition
ArgumentException	The supplied face id doesn't correspond to a face stored in this BRepBuilder object. -or- FinishFace() has already been called on faceId. -or- Please finish the previous loop by calling FinishLoop() before adding a new one.
ArgumentNullException	A non-optional argument was null
InvalidOperationException	This BRepBuilder object isn't accepting new data, either because it has already been used to build geometry, or because of an error. Consult the State property of the BRepBuilder object for more details.
