Syntax

public void InsertVertex(
	int index,
	XYZ vertexPoint
)

index Int32: The index of the vertex to come after this new vertex. Should be between 0 and NumberOfVertices.
vertexPoint XYZ: The point of the new vertex.

Exception	Condition
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).
ArgumentNullException	A non-optional argument was null
InvalidOperationException	Can't insert the vertex before the start vertex if the start point connects to one element.

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