No fear the help might be near!
Progman developer of MagiCAD, has launched MagiCloud. A cloud service where manufactures can publish their products amongst others in Revit format.
Simply log on to https://www.magicloud.com/, create an account to get access, and you will find yourself in a huge library of MEP components.
A substantial amount of manufactures, has already published content there, and more is coming to the looks of it. Users can even request manufactures to publish content to the site.
Content can be downloaded directly into Revit, and behave as traditional Revit families. Have fun exploring this new world of content.
