Revit MEP is a powerful Building Information Modeling (BIM) software designed to aid in the design, modeling, and documentation of Mechanical, Electrical, and Plumbing (MEP) systems. Revit MEP allows engineers, architects, and designers to collaborate more efficiently by providing an integrated platform for creating and managing MEP systems within a building. It is commonly used in large-scale construction and engineering projects to streamline the design and installation process.
