I love everything related to 3d design, it's something that I'm passionate about and I've been working on it for a long time. And not satisfied with that, I like video games and computers. In particular I recommend these two simple programs:

Clara.io: A 3D design program based on the web browser that includes all the common tools for modeling polygons, such as extrusion, beveling, slicing, cutting and loops. Includes V-Ray, which allows you to illuminate the Maya using an HDR image. It is also possible to create animated films by computer, since it supports basic animation of frames.

SelfCAD: An easy-to-use online tool for 3D design. It allows users to change tasks easily and offers them the possibility to continue with the project where they left it by just registering.
