I've spent a lot of time in the past learning 3D modeling and animation. I started with AutoDesk 3D Studio, then moved on to Maya and Blender (among others in between). I recently used that knowledge to create Instagram filters, which I made hundreds. I coudn't reach what I had in mind without programming and some knowledge in 3D modeling.
I believe that Draw 3D is a great app for those who want to experiment with 3D modeling and are looking for a simple interface that isn't intimidating, allowing them to start creating right away. Who knows, maybe it will inspire them to dedicate more time to learning advanced 3D software.
The app doesn't come with any tutorials, but it's not too complicated to understand. Think of it as a Windows Paint for 3D—simple yet versatile. If you're creative and learn the basics, you can create some really cool things with it.
