What do jewelry electro-painting designers need to learn?

Jewelry designers should learn basic jewelry design knowledge, including basic knowledge of gemstones, knowledge of precious metals, inlay principles, and jewelry making principles. Only by understanding these can you design jewelry, otherwise the designed jewelry cannot be made. In terms of drawing, renderings are drawn using PS and PAINTER, and usually pure hand drawing is used to create a feeling. If you are making 3D drawings, use jewelCAD.
