PointToPolyline

Converts a point data set to a polyline feature class. Attaches to the polyline attribute table the values of the attributes for the first and last point that form a single polyline. If your point data does not have Polyline ID and Order attributes, you can try the Connect Unstructured Points function.

Inputs:

A point feature layer
- REQUIRED: an ID field which value defines the points to be used for creation of each polyline
- OPTIONAL: an Order field that defines in what sequence the points describe the polyline. If no Order field is used the order is defined by the record number of the points
- OPTIONAL: a Link field. The values for the first and last point that will form a single polyline will be added to the polyline attribute table.
- OPTIONAL: Z Value field. If specified, a PolylineZ feature class will be created. The values in this field will be set as Z values for the vertices. If the input points have Z values, the user can specify the Z values of the input points to ve used by selecting "Features" for Z Value field.
- OPTIONAL: M Value field. If specified, a PolylineM feature class will be created. The values in this field will be set as M values for the vertices. If the input points have M values, the user can specify the M values of the input points to ve used by selecting "Features" for M Value field.

Outputs:

New polyline feature class
Fields to be added to the polyline attribute table
- [ET_ID] - the field used as Polyline ID
- [ET_FromAtt] - the values of the start point of the polyline in the Link field (if link field is used)
- [ET_ToAtt] - the values of the end point of the polyline in the Link field (if link field is used)

Notes:

There should be at least two points with the same value in the ID field in order polylines to be created.
The function entirely covers the functionality of the Point To PolylineZ(M) function available in pre 11.0 versions.

Example:

Source points	Source points attribute table

Resulting polylines ID Field = [PolylineID] ; No Order Used	Resulting polylines ID Field = [PolylineID] ; Order field = [PointOrder]

Command line syntax

ET_GPPointToPolyline <input_dataset> <out_feature class> <polylineID_field> {Z_value_field} {M_value_field} {order_field} {link_field}

Parameters

Expression	Explanation
<input_dataset>	A Point feature class or feature layer
<out_feature class>	A String - the full name of the output feature class (A feature class with the same full name should not exist)
<polylineID_field>	A String - the name (Case sensitive) of the field which values will indicate the points used to form a single polyline.
{Z_value_field}	A String - the name of the field which values will be used for Z values of the vertices. "Shape" can be used if the input points have Z.
{M_value_field}	A String - the name of the field which values will be used for M values of the vertices. "Shape" can be used if the input points have M.
{order_field}	A String - the name (Case sensitive) of a Numeric (integer or double) field which values will indicate the order in which the points describe the polylines. If no Order field is used the order is defined by the record number of the points
{link_field}	A String - the name of a field to be used as a link between the input points and the output. The values for the first and last point that will form a single polyline will be added to the polyline attribute table.
