3. Modelling software overview

An open source program for 3D modelling and animation. The main advantage of this software that it is free and easy to install. The disadvantage – it is quite complex to work with, requiring more skills and experience. The icons are not arranged in the menu bar. Knowing the name of a function makes it easy to call it through a search. This program has most of the benefits of the programs listed above. The modelling can be performed in more than one method. One way is to modify three-dimensional primitives, such as cube, cylinder, sphere. The feature of the program is the possibility of animation. It is possible not only to design a model, but also to see how it can actually move. For example, when constructing a hand, the app allows you to add restrictions so that your fingers can only bend to a predetermined angle, not 360 degrees. Another advantage is the material settings. Program focuses on 3D animation, silky material, hair, water, and other materials can be extracted for realistic images. Like other simulation programs, it has the ability to export the file to *.stl format, ready for 3D printing.
