Using the BOM (Bill of Materials) Tool in SolidWorks

     As the popularity of 3DVIA continues to grow and more and more users begin to understand the usefulness of the real time leveraging of 3D engineering content, some struggle with the concept of BOMs (Bills of Material) and how best to use this tool for management purposes - especially when it comes to Indented BOMs.


What is an Indented BOM?

An indented BOM is where we have an assembly consisting of raw materials, parts, and sub-assemblies together. Oftentimes it is required that a user display any variations or combination of this in a downstream publication. For instance, it may be necessary for one group in an organization to see every single component in the main assembly, while the end user or customer need only consider the sub-assemblies themselves.

Let's look at the following example. Below is a side-by-side comparison of what appears in SolidWorks (shown on the left) and what appears in 3DVIA (shown on the right).

Internally, we are only required to produce a comprehensive set of all components, both purchased and manufactured, that comprise the entire assembly. However, we are also tasked with sorting through these components, filtering out the purchased parts and hardware to provide a set of assembly instructions, and make a list of replacement parts externally for the end user.



In the BOM workshop, the workflow will consist of opening the main assembly and assigning BOM IDs to all parts with parent level set to 0; this provides us the most comprehensive collection of components. 





 Next, we begin to balloon out specific items, noting what appears onscreen in our BOM table.  If an item is chosen and the outcome isn't at the desired level, simply change BOM IDs to Selection and Reset BOM ID to the desired level for that specific item by means of Generate BOM ID. The original BOM ID for all other components is maintained, and only the selected item is modified.

Good luck! And remember, it's always the little things.
