I have Charlotte starter fittings (from a different software package) that when exploded will turn into 3D solids.  You could make equipment out of the solids, add CADMEP end connectors and/or any other needed data, as a temporary work around - at least it would give you placeholders with the correct space until you are able to access and download from the content site.

If interested, send me a private message with the needed charlotte fittings (Part Numbers) and an e-mail address
