Solid models on the other hand supply more data. Nonetheless, this type of modeling is widely used in 3D animation, graphic design and architecture. Still, surface models don’t contain any information about the content of the model, which makes surface modeling less appropriate for 3D printing. Free-form surfaces, such as Bezier curves and NURBS, and some other types of surfaces are most common. A surface 3D model is composed of a wireframe, which is amplified by descriptive surface data. Surface modeling is a mathematical method typically used in CAD software.
3D modeling makes it possible to create true-to-life designs, which can be then tested via physical simulations, animated or manufactured. 3D modeling technologies offers a mathematical representation of any surface of the objects in three dimensions, which cannot be implemented without technical software. 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. More than that, many designers even prefer 2D modeling for some purposes. Some CAD programs still offer only 2D features. 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. 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. 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. 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.
We’ve put together this extensive list of free CAD programs to help you make the right choice. That’s why it can be quite challenging not to get overwhelmed by options and pick the one that ticks all the boxes.

In many cases, free programs are just as good - and sometimes even better - as expensive professional applications.
On top of that, since advanced technology is becoming more and more accessible for everyday users, many enthusiasts enjoy CAD modeling as a hobby.Įach year, new and more advanced CAD software, both commercial and free, appears on the market. It is widely used by professionals in engineering, architecture, graphic design, film and video game development.
