Is there any advice on how I can convert ~75,000 polylines to polygons in Arc Basic (i.e., without Construct Polygon or Feature to Polygon functions)? I stumbled across ET GeoWizards, but don't know if there's a more seamless solution out there.

Do you have access to AutoCAD?

in CAD, import shapefile - select all polylines - use Object Properties panel, toggle Closed property to Yes - back in ArcGIS add data, browse to CAD .dwg, click in and just add the Polygon features - Export polygon features to shapefile
