I'm currently developing a parts database for a CAD system and would like to be able to give the user the option to use the edrawing viewer to open .sldprt files.  They are current able to open only a PDF of the model.  I'm using Visual Web Developer 2010 Express with SQL Server 2008 Express, VB code behind.  If anyone knows the specific command to accomplish this I would appreciate you passing it along to me.

Thanks!
