How does furniture change from design drawings to physical objects? What are the processes to take?

At present, furniture is still a traditional manufacturing enterprise, and there is no concept of modern manufacturing at all. Many companies don't have a design department, which is very confusing. Do you believe me if I say that I can directly take photos, copy and make proofs on how to go from design drawings to drawings? In fact, many companies do the same. However, when contacting several slightly standardized furniture companies, the basic design process is as follows: making a draft (several designers come up with creative concepts respectively, and then choose a higher one-creativity is not imaginary, but based on the understanding of the market and furniture consumers. ) three views (the draft has no size, just draw it casually. At this time, it is necessary to draw a standard three-view with CAD-mark the size and see the general structure) for proofing (also called 1: 1 model). At this time, you only need to make a general appearance according to the three views-try to save costs, not necessarily use the materials and colors determined on the drawings, but the size ratio must be correct).
