void InsertVertex(
	int index, 
	XYZ^ vertexPoint


Type: System Int32
The index of the vertex to come after this new vertex. Should be between 0 and NumberOfVertices .
Type: Autodesk.Revit.DB XYZ
The point of the new vertex.


To add a new vertex to the end of the wire, use AppendVertex(XYZ) .


Exception Condition
Autodesk.Revit.Exceptions ArgumentException The index should be between 0 and the number of vertices of the wire. -or- The vertex point cannot be added to the wire because there is already a vertex at this position on the view plane (within tolerance).
