MEP drafting and documentation software

AutoCAD® MEP software automates drafting and documentation tasks to help mechanical, electrical, and plumbing (MEP) designers and drafters create more accurate construction documentation. Share, collaborate, and coordinate more easily with architects, engineers, and contractors using reliable DWG™ technology.

Page view:


  • AutoCAD and AutoCAD Architecture support

    Work on flat 2D AutoCAD floor plans or AutoCAD Architecture geometric model architectural floor plans with AutoCAD MEP software. Use referenced architectural floor plans to design, tag, annotate, and create construction documentation of MEP system design.

  • Automatic space and zone calculation

    Assign engineering spaces from existing 2D architectural floor plans or AutoCAD Architecture geometric designs. Calculate room measurements automatically, including square footage, meters, and volumes per area. Use space and zone information when exporting to gbXML for import into Green Building Studio web-based energy analysis service or third-party analysis programs.

  • IFC data support

    Create, manage, and share MEP CAD data with others in the design process with Industry Foundation Classes (IFC) data. IFC export recognizes MEP objects from within AutoCAD MEP and exports them, along with MEP systems and their connectivity, to corresponding IFC Building Services entities and types.

  • Web-based help and learning tools

    Use the Autodesk Knowledge Network to access a community filled with pertinent learning information. Get access to integrated web-based help content, tips and tricks, and aggregated content to help support your continued learning.

    Construction & content

  • Section and elevation (enhanced) New

    You can now select objects in top-level Xrefs for editing when using the Edit Live Section command. A new setting in the properties for the 2D Section/Elevation result will force it to refresh when opening the drawing. In addition, grip states have been added to the section line to enable it to be modified without having to re-create it.

    Create and update 2D sections through dialog box reduction. To create a section, draw a section line. AutoCAD MEP generates a 2D section, based on the objects that are automatically included within the boundary of the section line. For even greater control, add and exclude additional objects.

  • Parallel routing improvements New

    You can now use parallel routing to have multiple objects follow the same routing preference and make connections automatically. Previously, to route and connect required respecifying the routing preference for each conduit or pipe. Simply making a straight connection required you to repeat the process for each connection afterward. Now, after the routing preference or connection for the first object is selected, all of the parallel objects will be completed.

  • Revision cloud

    Specify the default type of revision cloud: Freehand, Polygonal, Rectangular, or Object. The Annotation Scale automatically scales the length of the revision cloud arc. This results in a consistent appearance in views with different scales.

  • Documentation

    Create 3D models in AutoCAD MEP software and convert them to 2D for documentation needs. Improvements in the command line include the ability to auto-complete and differentiate commands and system variables.

    A wide palette of fonts and colors helps you create better-looking documentation. Improve drafting and modeling productivity with enhanced associative arrays.

  • Integrated content search

    Use AutoCAD Content Explorer to quickly search for design files, objects, and content within AutoCAD MEP. Easily search local and network drives for files containing content and objects to use within the design environment. Content search allows for more consistent company and industry standards, as well as use of real-world content.

  • AutoCAD block and symbol conversion

    Individually convert or batch-convert single or multiple AutoCAD blocks, MvBlocks, or MvParts to a device or schematic symbol. Extrude standard 2D blocks to create a 3D solid, and then add connectors to create AutoCAD MEP content for your MEP designs. In addition, you can convert AutoCAD blocks to orthographic symbols, as well as isometric symbols to facilitate your schematic design documentation.

  • Drawing management

    Manage project drawings more easily by creating coordinated views based on MEP design parameters. MEP design team members can access a centralized project directory of the most current documents, from project templates to sections and elevations.

  • Sloped pipe routing preferences

    Create more realistic pipe designs. Use routing preferences inside the application with sloped piping and male x female routing. Take advantage of specific piping content created for AutoCAD MEP.

    Productivity & usability

  • Style Browser (enhanced) New

    Explore Style Browser enhancements for AutoCAD MEP components, including more object types. You can now view, search, and add all system definitions from the Style Browser.

    Styles for devices, panels, plumbing fittings, and schematic symbol also now appear in the Style Browser. Click the binocular button next to the Routing Preferences in the Properties palette to display the routing preferences in the Style Browser.

    The Manage Content Library dialog now enables you to add a directory to the Content Library. MEP objects are grouped together, and when you expand an object node at the bottom of the drop-down list, the contents now scroll upward so all the objects under that node are visible.  

    The behavior of selecting system definitions has been standardized so the Style Browser will always be used. System definitions now include cable tray, conduit, and other electrical objects; and duct, pipe, plumbing, and schematic objects in the Object Type list.

    Routing preferences for conduit, duct, and pipe have been added to the Style Browser, helping reduce the size of MEP templates. In addition, the Style Browser now includes panels, devices, schematic symbols, and plumbing fittings.

    The Select Drawings dialog for the Content Library now includes A360. This enables you to share styles among geographically dispersed teams.

  • Assigning circuits New

    With the new CIRCUITASSIGN command, assign circuits to one or more selected devices directly using the command line.

    You can also find:

    • Information about the last used panel
    • A list of all the panels in the current drawing
    • A list of panels with all the circuits attached to them

    The PANELASSIGN command enables you to change the panel for multiple selected devices. If you select an object that is not a device, it is automatically filtered out of the list.

    You cannot assign devices that are not appropriate for the circuit. For example, you cannot assign a data connection to a power and lighting circuit.

    These new tools help improve your productivity when assigning circuits and changing panels.

  • Elbow duct fittings

    Choose the type of elbow that best fits your design when the sizes on both sides of the duct are equal. You can select Use Reducing Elbow, Use Straight Elbow and Reducer, or the new Use Reducing Elbow If Needed setting.

  • Automated property set definitions

    You can automatically attach property set definitions to architectural objects to complete quantity takeoff calculations. Attach new, modified, or existing property set definitions to newly created objects and their styles, as well as to existing objects.

  • Annotation and unit scaling

    When you change drawing units, object tags, text, and other annotation-scaled objects are properly modified. You have the option to rescale model and paper space objects, to rescale only model space objects, or not to rescale any existing objects.

  • Display order by layer

    Control the way architectural and MEP systems are displayed on construction documents. Set an order for layers in a list, and apply the display order for objects on each layer. Preview changes to the display order before they are applied to ensure that changes are predictable.

  • Block swap

    Easily edit your components as your design changes. Assign a different definition to block instances without re-creating the block.

  • Point clouds

    Save time and increase accuracy by using point cloud data to generate existing building conditions in MEP projects within AutoCAD MEP software. Bring 3D scans to life for renovation, retrofit, and restoration projects. Visualize the points more quickly and snap to the surface of your scanned objects directly within your modeling workspace. 

  • Status bar

    The Application status bar now includes the Display Configuration and Cut Plane tools. The status bar wraps onto 2 lines so that you can see all the selected controls. The Drawing status bar has been removed. 

  • UI Finder

    Use the Finder to easily locate frequently used commands directly from within Help content. An animated arrow points to the tool location in the user interface and in the status bar and Application menu.
