I have encountered a system for managing the production and design of a multi-part object: The Product Breakdown Structure. It has a bit of an overhead for a small project but it is so better to organize files and the advancement of a project, even more so if it is a collective project.
This is the file to be copied, not edited here.
The PBS consists of a systematic approach to the design of a product by its component instead of its steps or schedule. It hierarchizes assemblies (complete structures), into sub-assemblies (smaller component) into parts, individual objects.
I use it with my file system with a name: Tea Boat #110-004. I then can reference specifically at that part in the sheet and know what it is instead of searching within files name like Cover, back-01 and the like, which aren’t that descriptive. And since there is both the project name and the number, you don’t mix it up with your other project. In the Name field, you can give a detailed name longer than what is appropriate for a file name.
The other columns are for the state of the part, the number, the type of file and other information. It would need to be adapted to laser cutting and the type of product you make, and even could include detailing separated from the fabrication, but that is for each individual to make.
for a 3-4 parts object, using this is way too cumbersome. Also, since I think and design in 3d I see the direct relationship, but for a 2d designer, that may not help them, I don’t know.
I hope you find this interesting and helpful
