What is CAD software?

CAD, or computer-aided design and drafting (CADD), is technology for design and technical documentation, which replaces manual drafting with an automated process.

If you're a designer, drafter, architect, or engineer, you have probably used 2D or 3D CAD programmes such as AutoCAD or AutoCAD LT software. These widely used software programmes can help you draft construction documentation, explore design ideas, visualise concepts through photorealistic renderings and simulate how a design performs in the real world.

CAD software for architects, engineers, and designers

Building the Northwest Rail Link with BIM

Using BIM and intelligent objects to improve design

AutoCAD Civil3d + Revit + Navisworks Manage

SMEC is leading the design effort on key portions of the NW Rail Link. Using BIM to work with intelligent objects in 3d models, they can find issues that would be virtually impossible to spot otherwise. AutoCAD Civil 3D, Revit, and Navisworks help enable that process. 

Architecture, Engineering, and Construction Customer Stories

Free CAD software for students

Today’s challenges will be solved by tomorrow’s designers. 

We are proud to support students, teachers and academic institutions with free CAD software, access to license Autodesk software suites and provide continuous troubleshooting and support with our learning resources. Autodesk is committed to equipping students with the tools and resources to achieve academic and career success.

Use the same design software and creativity apps utlised by industry leaders worldwide, and start to imagine, design and create a better world.

Students at RMIT use Inventor to compete

Student engineers at Australia’s RMIT University used Autodesk's CAD software to improve their designs and processes, and to gain valuable experience with the same software professional engineers use every day.

Free CAD software for non-profits

Autodesk has several initiatives to make our CAD software suit available to non-profits. Our Technology Impact Program donates our CAD software to organisations that are using design for environmental or social good. If your non-profit organisation is designing a better world, you may be eligible for two licenses to our design suites.
