How To: Convert polyline features to polygon features with an ArcGIS Desktop Basic license
Polyline features can be converted to polygon features using different geoprocessing tools depending on the type of ArcGIS license. The Feature to Polygon tool is available with the Advanced ArcGIS Desktop license while the Construct Polygons tool is available with both the ArcGIS Desktop Advanced and Standard license. The Convert Polylines To Polygon tool is available with the Production Mapping license. With an ArcGIS Desktop Basic license, use the Merge tool and the Auto-Complete Polygon tool to convert polyline features to polygon features.
