12 Best CAD Software 2023 (For Every Skill Level!)
At 3DSourced we’ve covered everything 3D printing and 3D since 2017. Our team has interviewed the most innovative 3D printing experts, tested and reviewed more than 20 of the most popular 3D printers and 3D scanners to give our honest recommendations, and written more than 500 3D printing guides over the last 5 years.
CAD stands for Computer Aided Design, and CAD software are used all across the architectural, engineering, automotive and jewelry industries, just to name a few, and ever-present across rapid prototyping, product design, graphic design, and even in the making of prosthetics.
Both 3D CAD software and 2D CAD programs exist to create, edit, modify and test 2D and 3D designs before they ever get put into production and become physical parts, tools or objects.
Back before computer software and CAD, designers and engineers had to manually draw their designs on paper to create new products. This naturally had its problems — it was much slower, more prone to human error, and less repeatable.

CAD software offer massive advantages over drawing on paper, as you can instantly edit, make complex changes, and then export the model for production — such as by CNC machine, or by additive manufacturing or 3D printing. Iterations can be easily shared with clients or upper management, and changes made instantly based on their feedback.
In fact, 3D CAD tools are one of the reasons for increased productivity in manufacturing, and allow for more accurate and high quality parts to be produced and brought to market in record time.
Advanced CAD modeling software even simulate product or part usage to check for any weak points, and even use augmented reality (AR) or virtual reality (VR) technologies to see how your designs would look in the real world, before they actually exist.
In addition to these industrial uses, CAD software has also democratized design. Hobbyist 3D designers can now design stunning models at home, and sell their creations on 3D printing service marketplaces such as Shapeways for anyone who wants to buy one of their designs in brass or any other kind of material.
Autodesk are one of the largest 3D CAD software companies around, offering a variety of the best CAD software across a number of industries.
Advantages of CAD Software
- Faster and more effective: Can more easily visualize your part from all angles, and far quicker than on paper.
- Very accurate and precise: Details can be blown up by zooming in on specific areas, and perfectly symmetrical parts can be drawn that humans are not capable of replicating by hand.
- Quick iterations: Can quickly make changes based on feedback to optimize parts or designs. Some 3D CAD software even have features for running simulations for areas like thermal analysis.
