flipPolylineZ

Flip PolylineZ

Changes the directions of the polylines from a PolylineZ dataset. In the resulting feature class the polylines will be oriented Up Slope (start from the node with the lower Z value and finis at the node with higher Z value) or Down Slope (start from the node with the higher Z value and finis at the node with lower Z value)

Inputs:

A PolylineZ feature layer
Flip Option

Outputs:

A PolylineZ feature class.
- A field called ET_Status will be added to the attribute table. The values in this field will indicate whether a polyline has been flipped ("Flipped") or not ("Original")

Example:

Parameters

Expression	Explanation
Function Name	FlipPolylinesZ
<input dataset>	A String representing the input layer.
<output dataset>	A String - the full name of the output layer.
>Down Slope>	A Boolean indicating the direction of the slope. TRUE = Down Slope.

Running the function

ETGWPath used in the table below is the full path to ETGWRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETGeo Wizards\ETGWRun.exe")

Language	Syntax
Python	subprocess.call([ETGWPath, "FlipPolylinesZ", "input dataset", "output dataset", "Down Slope"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "FlipPolylinesZ" "input dataset" "output dataset" "Down Slope"
.NET using ETGWOutX.dll	FlipPolylinesZ(input dataset, output dataset,Down Slope)
ArcPy	arcpy.FlipPolylinesZ(input dataset, output dataset,Down Slope)

Notes:

<> - required parameter
{} - optional parameter
See examples for Python , .NET or ArcPy
The argument separator for StartInfo.Arguments is space. If a string might contain a space, you need to double quote it.
