View SLDPRT files from within the eDrawings IE plugin

I am trying to figure out how to view SLDPRT files within Internet Explorer. I have no problems with EASM files, click a link in a web page and the eDrawings plugin opens within EI and loads the file. But for some reason, an SLDPRT file comes up as an unknown file type and asks me to save or open the file in the eDrawings application. Is there a way to have it open in the eDrawings IE plugin?SolidworksEdrawings
