Target layer: Polygon Layer

Description:  Builds polygons in the target layer from the selected polylines in the Source layer. The polygons will be added to the target layer with the user specified Priority (see The concept of Polygon editing used in ET GeoTools)

Steps :

1. Select the polylines from the source layer that will be used to build polygons. Note that the polylines need to have a node in each intersection!!! The Intersect Polylines Tool can be used to ensure this
2. Click the ET Build Polygons Command. A dialog for selection of a source layer will be introduced ==> Select the polyline layer with already selected polylines. After selecting the source layer, press Enter and the process of building polygons will start.

Advantages: 

• Can be used in any version of ArcGIS (8.1 and above)
• Can be used  with any type of  license (ArcView, ArcEditor and ArcInfo)
• Can be used on layers with source Shapefile and Geodatabase feature class.

Parameters used: The function uses priority in order to preserve correct topological relationships between the new polygons and the existing ones. Adjust the "Add Polygon Priority" in the ET GeoTools Control Panel - Polygon Tab

Notes: 

• A very important condition for achieving good results is to have a clean, topologically correct source polylines. Use the tools available (Intersect Polylines , Clean Duplicates , Extend  etc.) to make sure that the source polylines are topologically correct.
• All the dangling polylines will be ignored.

Input	Result Source polyline layer - "ON"	Result Source polyline layer - "OFF"
