I want to know the CAD drawings required for appearance patent application (should the drawings have dimensions), but I don’t know how to start.

Appearance design refers to a new design suitable for industrial application based on the shape, pattern or combination of the product, as well as the combination of color, shape, and pattern.

As the name suggests, the design expresses the external shape or pattern of the product. When submitting the application, you need to provide six views of the same proportions and a brief description. There is no need to indicate dimensions in the views.

In addition, redundant lines such as dotted lines in the CAD drawing that indicate obstruction cannot be reflected in the application.
