Blender is a complex 3D modeling, animation, rendering, post-processing, interactive creation and playback (games).
With its help, static pictures, animation, models for games, as well as interactive information content in the form of independent programs are created.
It is possible to automate the program using Python scripts. In particular, import and export to popular file formats, such as 3D Studio and Wavefront Obj, are implemented in the form of scripts.

A simple drawing program for young children from 3 to 12 years old (eg kindergarten and primary school).
It is not an ordinary drawing tool. It's simple and fun to use. Sound effects and the animated nature of the program will help the user understand what is happening on the screen and will try to cheer him up.
