If you have been exposed to CAD, it is relatively simple to draw furniture drawings. You can draw them as long as you have all the sizes.

This makes it easier for you to actually arrange each dimension chain.

If you just want the effect, you don't need the exact size, just have the approximate proportion data.

If you want to engage in this line, you'd better get in touch with the actual furniture assembly work first, and then learn it for a while before drawing with CAD. You will have a lot of hands at the meeting, because you know how to draw, why do you draw like this!

I hope it works for you.
