In the drawing of an assembly, I insert the nomenclature in relation to a perspective view. I use the BOM Standard file for the bill of materials. But the names of some parts do not correspond to the assembly tree.
Hello; On mechanically welded there are several possibilities (your component seems to be an assembly of several mechanically welded...) :
=> Pay attention to configurations (Parts and Assemblies). => It is possible that several extrusions (mechanically welded), or parts, are on top of each other. => The BOM is not assigned to good view. => Updated the list of welded parts (Parts / Assembly) => The designation assigned to the part is not the correct one. => The component refers (external references) to another file. => BOM options: "Display configurations of the same part separately" Versus "Display configurations with the same name under a single item".
