Returns the angle of the tangent to the path at a given point.

Version Information

Version Added: Visio 2010

ANGLEALONGPATH(section,travel [,segment])

Name	Required/Optional	Data Type	Description
section	Required	String	The Geometry section that represents the path, specified by a reference to its Path cell (for example, Geometry1.Path).
travel	Required	Double	The percentage along the path from begin point to end point. Must be between 0 and 1.
segment	Optional	Integer	The 1-based segment of the path at which to calculate the tangent angle.

Double

If you include a segment value, ANGLEALONGPATH returns the value for that segment only.

If you include a segment value, ANGLEALONGPATH determines the point of the tangent by using travel to calculate the percertage along segment.

If either section or segment does not exist, Microsoft Visio returns #REF!.
