The course teaches you a set of ideas that can be reused on all models, so that you will no longer scratch your head when you encounter any shape. Different from the traditional training class, it teaches you the design and modeling of fading surface modeling, but returns to the essence of fading surface modeling and disassemble it, so that you can easily learn how to design fading surface modeling. I never do any modeling tutorial that teaches you to trace lines. I only pursue to explain the essence of each modeling, teach you to copy other people's designs correctly, understand the essence of other people's form designs, and apply this method to my own design projects. In fact, the gradual fading in product design is not as difficult as many people think. It is easy to design various gradual fading shapes by mastering its essence. Fallout modeling is not deliberately done like many institutions in the market, and fading is a natural result. The reason why the designer wants to do fading modeling is because he subconsciously pursues the methodology of "concave is convex". If you don't want to support the methodology of "concave is convex", please don't draw fading modeling when doing modeling design in the future.
