Robert,
You can turn your lines into area and/or point features using the Digitizer Tool. Simply select your lines, then right click and select the Advanced Feature Creation Options menu options to either create areas from your line(s) or points from your line(s). You will then be able to export that to an area or point shapefile.
Let me know if I can be of further assistance.
Thanks,
Mike
