how to make an inseparable assembly show BOM on dwg

[m_gillebaard]

Hi All,

We regularly have welded frames in our machines. The frames consist of multiple parts which will never be featured in the total part list of the entire machine itself, but the parts should be listed on the dwg to be able to make the frame.

What would be the best way make this happen?

At my previous employer i would simply filter out parts from the exported BOM based on a naming convention, but i'm looking for a more efficient method that results in a 1-on-1 match between the exported BOM while maintaining a listed structure on the dwg of the welded items.

any input is appreciated.

cheers!

Is your frame a subassembly?  If so, just place a parts list for the frame subassembly instead of the overall assembly, and you'll see all of its parts.

This seems so obvious that I feel like I must be misunderstanding or overlooking something that rules it out.  You may need to elaborate a bit on exactly how your drawings and models are organized to make it clearer exactly what you're trying to do.

Hi! Another approach is to change the individual frame member's BOM structure property to "Purchased." Then they will show up in the Part Only BOM View.

Many thanks!

You misunderstood indeed. If i were to make a BOM of an entire machine, it would need to include multple levels because of included subassemblies (meaning assembled subsets of manufactured and or purchased components) as well as welded subassemblies (such as frames or brackets that consist of multiple material parts.)

For regular subassemblies, the BOM of the entire project more or less does suffice. I need to select the structured setting to include all levels, and then manually multiply the items present in subassemblies if the subassemblies are present more than once.

For the welded assemblies, i would not need to see their parts in the top level BOM, because the welded subassembly is a single entity. The additional level that includes the material parts only pollute my BOM. However, on the dwg of the welded assembly, i do need to see the material parts that are used.

So basically i need to be able to place balloons in the dwg of the welded assembly showing the material parts, but if i make a drawing of the complete machine assembly, i would need to be able to place a balloon on the welded assembly and not see the number of the material parts, only of the welded assembly...

This is an issue that I encounter regularly. I have instances where a sub-assembly is used in multiple places. Sometimes I need the drawing to show the assy. as a single item, in other drawings I want the individual parts to show & the quantities to be rolled up in the parts list. Ideally, I would like to be able to set the drawing parts list to see the assy. as 'normal' or 'phantom' in different drawings but, because the BoM setting is a function of the .iam not the .idw, the change is global.
