Our picks are based on product engineer reviews, product engineering blogs and forums, and other publications from experts in the field. We also chose 3D CAD modeling software tools that have the most useful features. Of course, product engineers can be more productive only when they have the right type of 3D CAD modeling software tools, and that’s why we’ve rounded up 50 of the top tools available today. 3D CAD modeling tools especially have been beneficial to increasing the speed with which product engineers can generate models for tooling, prototyping, patenting, marketing, and manufacturing. Product engineers are designing, developing, and taking products to market at a dizzying rate today, and that’s due in part to the advancements in software tools over the past few years.
