Viewing CADRA files in EPDM (eDrawings)

Has anyone had the need to view CADRA files in EPDM?  We are implementing EPDM at a new site that uses CADRA for 2D electrical drawings.  Unfortunately the preview in EPDM does not have the capability of viewing CADRA files.  I am trying to get away from creating a PDF, doing some custom programming, or managing a stand alone viewer.  The scope of the viewable files within EPDM is for read only users on the shop floor who will not have a full version of CADRA on their machines.

Thanks,

Lucas
