Shapefile Importer for SketchUp

I have been working on a personal open source project for SketchUp. It will import point and polyline shapefiles. Just add a geo-location and make sure your shapefiles are in geographic coordinates WGS 1984. Please let me know if you come across any errors. It is in beta/development. Once I get some feedback and make improvements, I will place in the extension warehouse.
