Methodology for changing the indices of parts and assemblies in mechanical welding

Hello,

One of my customers integrates the index of his parts made with the Welded Construction module directly into the file name. He does not use PDM.

I encounter a difficulty when an element of a welded construction evolves, for example when a tube is modified .

In this case, I need to create a new subscript of the welded build file. However, the pipe file, which was created with the "Insert in a new part" function, remains linked to the old subscript of the welded build file.

So I end up with a tube that points to the old version of the welded construction, while I would like it to be able to follow the evolution of it.

What would be the simplest methodology to manage this type of case, especially when the elements of a welded construction are likely to evolve?

Thank you for your advice.
