I think we should create configurations of assembling shelves with screws... One assembly by type of shelf with these screws, so that if you change the assembly configuration everything will follow and the bill of materials too. (5:35 p.m. for my supervisor)
In addition, I would have to stay on a single shelf. Indeed, I work on SWOOD and this shelf is the basis of all the furniture I design. I then had to change the material of this shelf. This modification leads to a modification of the screws.
