To have the right mindset for 3D creation

But most importantly…

… to pass on an idea

Creativity can be refined, and so, learned.

Tools are pretty much useless without a base of

creativity

Create a “new” mindset

Principles and rules

1. Consider your design from it’s primitive volumes, then keep adding details

2. Model based on a reference

3. Scales and proportions based on reality

4. Good design

Start from primitives
