MagiCAD for Revit (MCREV) is an application that is built on top of AutoDesk’s Revit system. MCREV provides extended functionality to standard Revit operations and supplies thousands of real products to be used on Revit platform. These products, called families in Revit, contain both the graphical representation of the product as well as all the required technical information. Together they enable easy tools for designing a real product model of HVAC and electrical systems as well as to perform reliable technical calculations of the systems.
