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
Remarks
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!.
