Design and shape the world around you with the powerful, flexible features in AutoCAD 2013 software, one of the world’s leading 2D and 3D CAD design tools. Maximize productivity by using powerful tools for design aggregation and documentation, connecting and streamlining your design and documentation workflows.
AutoCAD brings robust 3D free-form design tools and powerful drafting capabilities to your platform of choice. It takes full advantage of the Mac OS X platform, with an intuitive, graphical user interface that makes it easy to bring your ideas to life.
Unlike most free software for creating 3D models it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. Thus it might be the application you are looking for when you are planning to create 3D models of machine parts but pretty sure is not what you are looking for when you are more interested in creating computer-animated movies.
Create and modify 3D models and 2D sketches on your Mac. Generate 2D layouts, enable real-time visualization, collaborate on your projects with other users and store your designs in the cloud to access them from any device. Import files from other Autodesk programs in SAT, STEP, DWG and Autodesk Inventor formats.
