    Mechanical design productivity

  • Command preview and contextual menus New

    Preview chamfers, fillets, and offsets as you select the objects to use in the command. View and modify parameters using the new ribbon contextual menu for fillet and chamfer properties.

  • 700,000 standard parts and features

    Rely on a comprehensive set of standards-based components to produce accurate mechanical drawings and get more consistent results on the shop floor. Insert content and let AutoCAD Mechanical clean up the surrounding geometry so you don’t have to edit it manually. The software supports international mechanical drafting standards and includes libraries of more than 700,000 standard parts.

  • Document 3D CAD models

    Browse Inventor files and create new linked AutoCAD Mechanical drawings based on the most current 3D designs. Incorporate design revisions with associative links that alert users to changes and regenerate the 2D drawing. Create section and detail views from any existing drawing view. Use AutoCAD and Inventor 3D models to produce associative and nonassociative 2D drawings, or generate nonassociative 2D drawings from other 3D models.

  • Reusable mechanical drawing detailing tools

    Using a specific tool for almost every aspect of the mechanical CAD drafting process can save you time. Intelligent mechanical drafting tools enable you to re-edit features without having to remove and recreate the original feature. For example, you can easily resize a chamfer or fillet through the original dialog box parameters by double-clicking the chamfer or fillet.

  • Layer management

    The layer management system automatically places items on the correct layerwith correct color and linetypeas you create your mechanical drawing. You can easily customize AutoCAD Mechanical drafting software based on your company requirements, and use layer management to differentiate your drawings.

  • Hidden lines

    Update geometry automatically when changes occur, and minimize time-consuming manual redrawing. Define simple foreground and background selections that redraw geometry to show hidden or dashed lines of parts obstructed by other parts in your design. Identical parts can have different geometrical appearances when hidden. AutoCAD Mechanical recognizes that they are still identical  if you need to change the design or get an accurate count for the parts list.

  • Mechanical drafting standards update

    ISO 1302-2002 surface texture symbols support surface indication leaders. You can attach these symbols to edges, and they remain associative to objects, but they originate from a surface or face.

  • Machinery generators and calculators

    Get comprehensive tools to more efficiently build mechanisms from paper catalogs and manual calculations. Built into the application environment, these machinery generator and calculator tools—including shaft, spring, belt, chain, and cam generators—can help you make small, iterative changes to improve mechanical drawings. They not only create parts according to your specifications, but they also create all the reports and calculations you need to analyze the design.

  • Custom part publishing support

    All part publishing features that apply to standard parts are available for custom parts. Add custom parts to the existing content library to share within your organization. Provide intelligence to these parts by adding parametric constraints to them through an easy-to-use environment. Use key features, including a Grip Snap tool and a Size-by-Drag tool.

  • Extended draw toolbar for manufacturing

    AutoCAD Mechanical provides additional mechanical drawing and drafting options beyond what’s available in AutoCAD, including more than 30 options for rectangle, arc, and circle creation; automatic centerline creation and updating; specialty lines for breakout views and section lines; and a full suite of construction lines for aligning drafting views.

  • Infer constraint integration

    Geometrically and dimensionally constrain rectangles, symmetrical lines, and centerlines in mechanical drawings. Turn on Auto Constrain to automatically infer geometrical constraints while creating objects. Once constrained, rectangles remain rectangular and centerlines remain in the center of circles or holes.

  • Content manager Standard Parts live update

    Get integrated live updates to your Standard Parts library as revisions and new standards become available through content manager. Automatically update the parts within your design to reflect periodic revisions.

  • Custom content library

    Create and save standard or custom parts and features for easy access and reuse. Save time and increase efficiency—use the Favorites folder to bookmark parts and features you use daily.

    Mechanical engineering documentation

  • Note template gallery New

    Access the note template symbol library directly from the ribbon menu. Recently used note templates, previews of each note, and tooltips provide visual references for selecting notes to use in the design.

  • Total mass in bill of materials (BOM) New

    Quickly determine the mass of entire assemblies directly in the BOM view. Using quantity and mass component properties of each part in the assembly, the software calculates the total mass and displays it in the BOM list. The total mass property automatically updates anytime you add or remove components from the assembly.

  • Autodesk Synergy for mechanical engineering

    Create associative section and detail views of 3D models created in AutoCAD, Inventor, and competitive products, including SolidWorks, Pro/ENGINEER, CATIA, Rhino, and NX applications. Instantly update drawing views, edge display, and location as you make engineering changes. Detail views include full control of shape, scale, and annotations. Leader note capabilities include Holes and Extract Thread Data.

  • Smart mechanical engineering dimensions

    Create dimensions using abbreviated dialog boxes that conveniently control and expand only the relevant variables for manufacturing. With automatic dimensioning, you can create multiple dimensions with minimal input, resulting in instant groups of appropriately spaced ordinate, parallel, or symmetric items.

  • Support for international drafting standards

    AutoCAD Mechanical engineering software supports ANSI, BSI, CSN, DIN, GB, ISO, JIS, and GOST drafting environments. Adhering to a standard environment can help to improve team communication and drive consistent production results. The software also includes drafting tools for creating standards-based surface texture symbols, geometric dimensioning and tolerances, datum identifiers and targets, notes, taper and slope symbols, and weld symbols.

  • Associative balloons and bills of materials

    Create associative parts lists and bills of materials (BOMs) specifically developed for manufacturing, and that automatically update as the design changes. AutoCAD Mechanical engineering software includes support for multiple parts lists for each drawing, collapsible assemblies, automatic recognition of standard parts, and customizable options so you can revise features to match current company practices.

  • Dimension in-place editor

    Select multiple dimensions at once, and see a real-time preview when you make modifications. Insert symbols, add or modify fits and tolerances, add prefix or suffix text, and modify precision. With multiple diameters along a shaft selected, applying an h6 fit applies the tolerance to each dimension, based on the nominal size.

  • Bill of materials (BOM) migration

    AutoCAD Mechanical software supports multiple templates. BOM setup is easier with automatic mapping of BOM properties and automatic creation of migration templates.

  • JIS and DIN content libraries

    Get extensive content libraries for Japan (JIS) and Germany (DIN). JIS library includes G 3350:2009 Light Gauge Steel and JIS G 3452:2010 Gas Pipe standards. The DIN library includes DIN 6917:1989, DIN 6918:1990, and DIN 6918A:1990 Fasteners.

  • Autodesk Content Explorer

    Quickly find your design content based on file objects or text attributes. Content Explorer creates an index of your data based on where you instruct it to look. So you can quickly access files, blocks, layers, linetypes, and styles. You can also access and insert data into DWG™ files.

  • Mechanical drafting annotation monitor

    Check for disassociated annotations in the model space, as well as in each paper space layout. An in-canvas badge flags each disassociated annotation (such as dimension, leader note, or surface texture symbol). The badge also offers access to the Delete and Reassociate commands, giving you complete feedback on the accuracy of your documentation.
