The apps are divided into three sectors, each covering programs best suited for different levels of CAD proficiency: beginners, intermediate users and professional-level users.
To avoid confusion it is important to mention that some of the programs are freemium, while others can be free only for select groups, such as students and teachers. If you’re new to the world of CAD and 3D modeling software, and shaky on some of the basic terms, you should take a look at our mini-dictionary of CAD-related terms.Īt first, CAD programs were developed only to work with 2D. It was possible to work only with top, front and side views of the model, just as you would if you designed without digital aid. Some CAD programs still offer only 2D features.
More than that, many designers even prefer 2D modeling for some purposes. Unfortunately, it is very difficult to work on complex projects in 2D, that’s why most 2D CAD programs are aimed at working with simple technical geometry.ģD modeling, on the contrary, gives an opportunity to design complex profound models. 3D modeling technologies offers a mathematical representation of any surface of the objects in three dimensions, which cannot be implemented without technical software. 3D modeling makes it possible to create true-to-life designs, which can be then tested via physical simulations, animated or manufactured.
