Revit MEP Features Include:

• Mechanical Design Criteria. Create color-fill plans by using design parameters and display legends to communicate design intent visually, rather than deciphering spreadsheets and schedules. Use color-fill plans to quickly facilitate design reviews and present your design criteria to clients for review and validation. Color fills are linked to parameter values in the model so the plans are automatically coordinated as design changes are made. Create any number of schemes and easily maintain them for the life of the project.
• Mechanical Duct and Pipe System Modeling. Mechanical functionality offers 3D modeling for ductwork and piping to create HVAC systems. Intuitive layout tools make 3D modeling fast and easy for even the first-time user to master. Built-in calculators are available for sizing mains, branches, and even whole systems at a time. Easily modify the model by dragging design elements to move or change them on the screen, in almost any view. All model views and sheets are automatically coordinated whenever a change is made in any view for accurate and coordinated designs and documents at all times.
• Electrical Lighting and Power Circuitry. Minimize errors in your electrical design by using circuits to track loads, number of attached devices, and circuit lengths. Define wire types, voltage ranges, distribution systems, and demand factors to help ensure the compatibility of electrical connections in your design, and prevent overloads and mismatched voltages. Identify voltage drops, apply derating factors, and even calculate the estimated demand loads on feeders and panels to size equipment as you design. Plus, take advantage of circuit analysis tools to quickly total loads and generate reports for accurate documentation.
• Electrical Lighting Calculations. Revit MEP uses the zonal cavity method to automatically estimate lighting levels in rooms based on the lights placed in the space. Set the reflectivity values of the room surfaces, attach industry-standard IES (Illuminating Engineering Society) data files to lighting, and define the calculation workplane height. Then let Revit MEP automatically calculate the estimated average illumination value for the room.
• Plumbing System Modeling. Gain full 3D parametric modeling of plumbing system layouts with Revit MEP. Intuitive layout tools make 3D modeling fast and easy. Just drag design elements to move or change them on the screen, in almost any view. Model sloped piping according to industry code. Simply define the rise over run and lay out your plumbing design, while the software automatically places all risers and drops and calculates inverts elevations as you design. All model views and sheets are automatically coordinated whenever a change is made in any view for accurate and up-to-date designs and documents at all times.
• Revit Parametric Components. Parametric components are the basis for all building elements designed in Revit MEP. They offer an open, graphical system for design thinking as well as an opportunity to express design intent at increasingly detailed levels. Parametric components can be used for the most elaborate assemblies for mechanical, electrical, and plumbing (MEP) engineering systems. Best of all, no programming language or coding is required.
• Bidirectional Associativity. A change anywhere is a change everywhere. All Revit MEP model information is stored in one place. As a result, any information that gets changed is effectively changed throughout the entire model simultaneously. Parametric technology automatically manages all change propagation.
• Revit Architecture Support. Since Revit MEP is built on the Revit platform, coordination among MEP team members and with architects using Revit® Architecture software has never been easier within the complex building design process. Revit Architecture models are the best way to support engineering design criteria. Revit MEP uses the architectural spaces to support load calculations, track airflow in rooms, and coordinate panel schedules.
• Revit Structure Support. With Revit MEP it is possible to have complete design and documentation coordination with structural engineers using Revit® Structure software. Working in a building information model makes it possible to uncover potential conflicts between the MEP and structural designs early in the design process, resulting in cost savings.
• Building Performance Analysis. Take full advantage of building information modeling to provide better decision-making support through the use of building performance analysis tools. Provide significant benefits to the sustainable design process, supporting the goal of a better-performing building. Perform heating and cooling load, LEED daylighting, thermal energy, and other analyses using Revit MEP and the IES Virtual Environment.
• Import/Export Data (gbXML) for Third-Party Analysis. Revit MEP enables you to export the building model to gbXML (green building extensible markup language) for energy and load analysis. When the analysis is complete, import the data back and store the results in the model. And for additional analyses and calculations, export this same information to a spreadsheet for easy sharing with team members who don’t use Revit MEP software.
• Publish to DWF. With the click of a button, publish your designs as DWF™ files for easy viewing in Autodesk® Design Review. Create 3D DWF files, complete with engineering data, for better communication of design intent. And with DWF technology, team members can review and redline as well, making the DWF specification an efficient means to distribute and share data quickly and efficiently.

AutoCAD MEP Features Include:

• Discipline-Specific Tool Palettes - Provide all team members with the right tools for the job. A discipline-specific engineering tool palette displays only the relevant tools for the mechanical, electrical or plumbing engineering user, providing consistency across project drawings. Organise the tool palette to specific company or individual preferences. Now engineers, designers and drafters can easily modify tool palette size, shape, system type and much more using in-place editing. Simply select the tools you want to change and modify the common properties all at once, streamlining the design process and improving productivity.
• Conversion of AutoCAD Blocks and Symbols to AutoCAD MEP Systems Content - Easily migrate your existing AutoCAD® symbols to AutoCAD® MEP content for production of construction documentation. Existing AutoCAD blocks and symbols are easily converted to AutoCAD® MEP content, in one easy step, using the new symbol and device converter.
• Construction Annotation - Simplify the process of annotating construction documents with automated annotation tools. AEC dimensions and dynamic labels update automatically as the design changes, minimising manual updates. Hidden lines and hatch-on objects make it easy to interpret design intent. In this release, new ease-of-use tools and enhanced grips streamline the use of break marks, labels and scheduling tags. Display the schematic view of an object rather than the model-generated view. Create schematic block, annotation or both that scale when the part size changes.
• Single Line and Double Line - AutoCAD MEP facilitates routing of ductwork, piping, cable tray and conduit with intuitive design tools that automate much of the layout process. Increase productivity with automated routing solutions based on default project settings and common industry design standards. With improved connectivity between objects, automated system layout is even easier. Improved layout tools make it easier to convert one-line designs to double line through intuitive onscreen modification. Custom fittings enable unique layouts to be designed with the creation of on-the-fly fittings. Options such as segment length help reduce time spent performing takeoffs by graphically depicting each segment piece required for the layout according to manufacturers’ specifications.
• Duct, Pipe and Wire Sizing - Automatically size ducts, plumbing and piping, and wire during design layout using traditional design methods that incorporate code-driven requirements and industry standards. These methods eliminate the need for many tedious manual recalculations. This release introduces improved connectivity that supports enhanced sizing capabilities, including one-line duct conversion to double-line ductwork based on resizing of the system and sizing of systems through external references (xrefs).
• Enhanced AutoCAD Commands - Copy, move and align all in one step with enhanced AutoCAD commands unique to AutoCAD MEP. Automatically snap in the required orientation and view. Quickly array along duct, pipe, conduit or cable trays and easily fillet plumbing piping.
• Sections and Elevations - Create sections and elevations in seconds rather than hours. When designers make a change in the design, sections and elevations update automatically. This capability saves time and helps ensure accuracy in the design. Each design change is reflected in real time, minimising tedious manual updates.
• Systems - Provide a fast and consistent method for laying out parts that represent real-world building systems, such as air supply or return systems. When designers use systems during design layout, new parts inherit the current system’s defaults, such as rise/drop symbology and display properties. Designers can apply changes simultaneously to all connected parts. And since AutoCAD MEP manages layers, systems can be assigned to layers, helping ensure the accuracy of designs. In addition, this release provides support for new system types.
• Extended Engineering Data - Easy access to engineering data in your system model enables data sharing for automated sizing calculations, enhanced scheduling and improved annotation. Extract engineering data from your models in standard file formats, such as gbXML (green building extensible mark-up language) and ddXML (duct design extensible mark-up language). Take advantage of the application programming interface (API) for interoperability with third-party analysis, cost estimating and fabrication applications. Such interoperability minimises manual transfer of design data and helps to ensure the accuracy of your designs.
• Dynamic Dimensions - As engineers, designers and drafters make changes to their mechanical, electrical or plumbing design, they benefit from the Dynamic Dimensions feature. This feature gives real-time feedback on the exact location of a move or copy change within a design. This capability facilitates Heads-up Design™, speeding the production process for faster delivery of construction documents.
• Scheduling - Create schedules in seconds, saving hours over traditional CAD drawing processes. Schedules are automatically updated as the design changes. This capability helps to reduce errors in construction documents. Now engineers, designers and drafters can schedule engineering system data, calculate values and use new table styles to lay out room and analysis schedules.
• Engineering Display Themes - Use display themes to graphically present and analyse design intent. For example, use the display theme By Velocity or Friction Loss to validate system performance for a particular area or room. Also use the display theme By Pressure Class to visually show the high, medium and low-pressure per piping class to easily identify potential design flaws. Display themes are depicted as colour-filled displays complete with legends.
• Direct Grip Manipulation - Streamlining the design process by virtually eliminating dialogue boxes, grip manipulation enhances design productivity by keeping engineers, designers and drafters focused on the design and documentation task at hand. With a single click, easily perform design and documentation changes, such as stretching the length of a duct or changing the Z elevation, while maintaining connectivity between objects.
• Setup and Deployment Options - Flexible setup and deployment options provide for consistent standardisation and management of software installations for both network and single-user installations. And through the use of profile-based shortcuts, the software can now automatically default to specified template drawings when opened.
  
• Increased Performance - Get better overall performance with AutoCAD MEP software. Manage your projects with tools that are now smoothly integrated with the AutoCAD® Sheet Set Manager, increasing the speed of drawing co-ordination. And access parts through the Add and Modify dialog boxes faster from the streamlined, comprehensive parts catalogues.
