Polyline To Polygon

Polylines To Polygons

Converts closed polylines (and polyline chains) to polygons

All closed polylines will be converted to polygons.
The attributes of the polylines will be transferred to the corresponding polygon features.
If the "Use closed polyline chains" option is used, the polylines that form closed chains will be used to create polygons. The attributes of the first polyline of the chain will be transferred to the polygon feature
For advanced polygon creation use the Build Polygon function

Parameters

Expression	Explanation
Function Name	PolylinesToPolygons
<input dataset>	A String representing the input layer. Must be of Polyline type.
<output dataset>	A String - the full name of the output layer.
{Force Closure}	A Boolean indicating whether polylines that are not closed and the distance between the from and to nodes is smaller than the tolerance specified to be closed.
{Close Tolerance}	A Double representing the distance to be used for closing the non closed polylines.

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, "PolylinesToPolygons", "input dataset", "output dataset", "Force Closure", "Close Tolerance"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "PolylinesToPolygons" "input dataset" "output dataset" "Force Closure" "Close Tolerance"
.NET using ETGWOutX.dll	PolylinesToPolygons(input dataset, output dataset, Force Closure, Close Tolerance)
ArcPy	arcpy.PolylinesToPolygons(input dataset, output dataset, "Force Closure", "Close Tolerance")

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.
