When working with 3D models, the animated presentations are best for presenting created devices. They allow quick and clear presentation of the ideas, principles of the mechanism working, and it are also more understandable for people not involved in the project.
I originally used Inventor's to create them, but the capabilities of this software quickly turned out to be too small. That's why I became interested in the blender and what it offers.
