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.

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, "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")
