Split Polyline Layer Basic

Split Polylines

Splits the features of a polyline layer.

A polyline feature class - new node created in each split point. The attributes will be distributed according the user specified attribute Cell SizeY.

Range attributes from numeric fields can be handled.
If the Segment length method is used
- all the segments will have the user specified length except for the last one
- if the assigned length is larger than the length of a specific polyline, the polyline will be copied to the output as is
- the splitting starts always from the start points (From Node) of the polylines

Before Split

Split in all Vertices

Split in equal segments

Exact length + remainder

Expression	Explanation
Function Name	SplitPolylines
<input dataset>	A String representing the input layer. Must be of Polyline type.
<output dataset>	A String - the full name of the output layer.
<Split Option>	Required. A String valid values: "Vertex" "NumberIntervals" "EqualLength" "Length" "NumberVertices"
{Split Tolerance}	A Number which value depending on the option defines: "Vertex" - not used "NumberIntervals" - the number of intervals per polyline "EqualLength" - the desired length of the output polylines "Length" - the length of the output polylines "NumberVertices" - the number of vertices per polyline.
{Update Rules}	A String representing a list (separator ";") of fields and update rule for each field. Example: "Field1 AddressRange Field2; Field3 Copy; Field4 Proportion"

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, "SplitPolylines", "input dataset", "output dataset", "Split Option", "Split Tolerance", "Update Rules"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "SplitPolylines" "input dataset" "output dataset" "Split Option" "Split Tolerance" "Update Rules"
.NET using ETGWOutX.dll	SplitPolylines(input dataset, output dataset, Split Option, Split Tolerance", Update Rules)
ArcPy	arcpy.SplitPolylines(input dataset, output dataset, "Split Option" , "Split Tolerance", "Update Rules")

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.
