CleanDanglingNodes

Cleans the dangling nodes from a polyline layer using user specified dangling tolerance

Inputs:

Outputs:

Notes :

Use Export Nodes Wizard to check the status of a data set. It will analyze the nodes of a polyline layer and will create a Point feature class with classified nodes.
It is recommended before proceeding with cleaning the dangling nodes to use the Clean Polyline Wizard to ensure that all the polylines are intersected and the very small over and undershoots are cleaned with the Fuzzy tolerance.
A Fuzzy tolerance of 0 may be used if the original shapes have to be preserved exactly the same. In this case only the intersections will be created

Examples:

Before Clean Dangles
After Clean No "Node Snap" or 'Nearest Snap" used
After Clean "Node Snap" used
After Clean "Node Snap" and "Nearest Snap" used

Command line syntax

ET_GPCleanDangle <input_dataset> <out_feature class> <dangling_tolerance> {closest_node_snap} {nearest_feature_snap}

Parameters

Expression	Explanation
<input_dataset>	A Polyline 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)
<dangling_tolerance>	A Double representing the tolerance to be used. The polylines with dangling nodes within distance smaller than this value to existing features (depending on the options used) will be extended/snapped to the closest existing feature
{closest_node_snap}	A Boolean - if True, the ends of the dangling polylines that could not be snapped to an existing polyline by extending in the direction of the last segment will be snapped (if the dangling node is within a distance smaller than the <dangling_tolerance> to an existing node) to the closest existing node.
{nearest_feature_snap}	A Boolean - if True, the ends of the dangling polylines that could not be snapped to an existing polyline by extending in the direction of the last segment or to an existing node will be snapped (if the dangling node is within a distance smaller than the <dangling_tolerance> to an existing polyline) to the closest point of the closest polyline
