Namespace: Autodesk.Revit.DB Class: BRepBuilder

BRepBuilder.AddCoEdge

Method

Description:
Add a co-edge associated to a previously added edge. A co-edge represents the use of an edge on one of the edge's faces.

Syntax

public BRepBuilderGeometryId AddCoEdge(
	BRepBuilderGeometryId loopId,
	BRepBuilderGeometryId edgeId,
	bool bCoEdgeIsReversed
)

Public Function AddCoEdge ( 
	loopId As BRepBuilderGeometryId,
	edgeId As BRepBuilderGeometryId,
	bCoEdgeIsReversed As Boolean
) As BRepBuilderGeometryId

public:
BRepBuilderGeometryId^ AddCoEdge(
	BRepBuilderGeometryId^ loopId, 
	BRepBuilderGeometryId^ edgeId, 
	bool bCoEdgeIsReversed
)

member AddCoEdge : 
        loopId : BRepBuilderGeometryId * 
        edgeId : BRepBuilderGeometryId * 
        bCoEdgeIsReversed : bool -> BRepBuilderGeometryId

Parameters

Parameter	Type	Description
loopId	BRepBuilderGeometryId	Id of the loop containing the new co-edge.
edgeId	BRepBuilderGeometryId	Id of the co-edge's edge, previously created by a call to addEdge().
bCoEdgeIsReversed	Boolean	True if the co-edge's topological direction in its face is opposite to the edge's parametric direction, false otherwise. The topological directions of the co-edges in a loop must be consistent with the direction in which the loop co-edges appear in the loop, and the loop orientations so defined must follow the convention that outer loops are oriented counter-clockwise and inner loops are oriented clockwise, with respect to the face's orientation.

Return Value

Type	Description
BRepBuilderGeometryId	Id of the edge, to be used in calls to other BRepBuilder methods such as AddCoEdge().

Exceptions

Exception	Condition
ArgumentException	The supplied loop id doesn't correspond to a loop stored in this BRepBuilder object. -or- The supplied edge id doesn't correspond to an edge stored in this BRepBuilder object. -or- FinishLoop() has already been called on loopId. -or- The edge already has two coedges associated to it. -or- Inconsistent use of the edge by co-edges is detected: both co-edges have the same bCoedgeIsReversed parameter. -or- The edge has already been added to this face. -or- There is a gap between this co-edge and the previous co-edge in the loop.
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.
