This video shows a few different ways of using the Normal Tools in Cinema 4D. These tools have been around for a while, so this tip should work in almost any version of Cinema 4D.
The Normal Move, Normal Scale, and Normal Rotate tools are a trio of utilities that operate on Polygonal objects. They use the hyper-local coordinate system of the selected polygon’s Surface Normal. Very useful and or interesting effects can be produced by using these tools cleverly. Check out the video for some ideas, and share any of your own techniques in the comment section below. I’d love to hear from you.
