ANGLEALONGPATH Function
Returns the angle of the tangent to the path at a given point.
ANGLEALONGPATH(section,travel [,segment])
Parameters
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. |
Return Value
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!.
