Signature

RetVal = object.GetBulge(Index)

Object

LightweightPolyline, Polyline
The object or objects this method applies to.

Index

Integer; input-only
The index location of the vertex you wish to query. The index must be a positive integer beginning with zero.

RetVal

Double
The bulge value for the vertex at the given index.

Remarks

Polyline: this method will fail if the polyline Type property is not acSimplePoly.

The bulge is the tangent of 1/4 of the included angle for the arc between the selected vertex and the next vertex in the polyline's vertex list. A negative bulge value indicates that the arc goes clockwise from the selected vertex to the next vertex. A bulge of 0 indicates a straight segment, and a bulge of 1 is a semicircle.
