PolygonToPolyline

Polygon To Polyline

Running programmatically

Converts a polygon data set to a polyline feature class

Inputs:

A polygon feature layer

Outputs:

New polyline layer

Notes :

Each ring of a polygon will be represented by a single polyline. The common boundaries between the polygons will be represented by duplicate polylines. The Clean Polylines Wizard can be used to create intersections and remove duplicate lines.
The attributes of the original polygons are transferred to the resulting polylines.

Running Programmatically

Parameters

Expression	Explanation
Function Name	PolygonsToPolylines
<input dataset>	A String representing the input layer. Must be of Polygon type.
<output dataset>	A String - the full name of the output layer.
{Keep Z}	A Boolean indicating whether if the input has Z values to keep them in the output.
{Keep M}	A Boolean indicating whether if the input has M values to keep them in the output.

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, "PolygonsToPolylines", "input dataset", "output dataset", "Keep Z", "Keep M"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "PolygonsToPolylines" "input dataset" "output dataset" "Keep Z" "Keep M"
.NET using ETGWOutX.dll	PolygonsToPolylines(input dataset, output dataset, Keep Z, Keep M)
ArcPy	arcpy.PolygonsToPolylines(input dataset, output dataset, "Keep Z", "Keep M")

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.
