AutoCAD Mechanical is AutoCAD-based software that increases productivity and simplifies complex mechanical design tasks. Autodesk's in-house mechanical CAD includes all the functionality of AutoCAD, one of the world's most widely used 3D CAD software, while additionally including comprehensive libraries of standards-based parts and tools for automating common mechanical CAD tasks.

AutoCAD Mechanical speeds up the mechanical design process:

• Access to vast mechanical component libraries: more than 700,000 parts and standard machining operations
• Creation of associative section and detail views of 3D models
• Creation of intelligent mechanical engineering dimensions
• Use of intelligent and reusable mechanical drawing tools
• Support of drawing standards and international graphic standards
• Automated creation of parts lists and BOMs
• Advanced management of layers and layer groups
• Creation of hidden lines when some objects overlap others
• Automatic calculation of the mass of an assembly in the parts list
• Integration of constraint deduction
• Ability to insert details into native part and assembly models in Autodesk Inventor
• Ability to preview fillet, chamfer, and offset commands and context menus
• Efficient design analysis, including shaft, spring, belt, chain, and cam generators and machinery calculators
• Exchange of model data between CAD systems: import and export of STEP files
