I suggest you buy a workbook of Interior Decoration Engineering Drawing, which will be published by China Light Industry Press.

There are also Furniture Cartography by Light Industry Press and Furniture Research by Northeast Forestry University Press. These books are good books for studying furniture design. The first comparison foundation focuses on drawing, and the last two are extensions.

I study furniture design, and drawing is the foundation and the difficult part, which requires a lot of energy. There are some furniture structures you need to know. I wish you success! If you have any questions, please come to me and discuss with each other.

Baidu knows that China Furniture Group will answer your questions, hoping to help you.
