Showing assembly groups in BOM

I've been trying to find an answer to this problem for days and cant believe it cant be done!

What I'm trying to do is make a fastener/stud list for our main assembly. I'm using a filter by rule in the BOM that will only show the fasteners, this is done by a parameter 'REGION' that I build into the studs with a number assigned to it. This is so I dont have to create a new assembly for pipework/fastners/gasket lists, the frame is set up to only see the relevant items.

This works fine, but.... I have grouped the fasteners in the assembly and named the group by the interface name, ie 'COVER_PLATE'. This is partialy to keep the assembly tree tidy but I REALLY want to get the BOM to display the group name as when the production guys make the studs up the bag them by interface plate. This is the way they have been doing it in AutoCAD for years and I dont want to cause major upset in the masses by changing this!

This seems to be a simple thing that is made exteamly complicated!

Hi, Brian:

There was another BOM thread a while back,

Maybe something in there will give you an idea. I've never tried to pull out "Group" data from the tree, just used it as local housekeeping.

when I read this, the first thing I thought of was Pro/PROCESS for Assemblies. This lets you document the building of an assembly through several process steps with Simplified Reps and explode views. So, it might be possible to do something even more modest, like showing the BOM of some kitted components, with a Rep. The problem that needs to be overcome is that each Rep basically changes all the find numbers, each associated BOM starting with index number 1. But this can be overcome with 'Table>Repeat Region>Start index' and renumbering the first item to whatever it is in the master BOM.

Another thing I thought of is to substitute an actual assembly for your group but giving it the name of your group. When you insert the assembly ahead of the components, you just use 'Edit>Restructure' to get your components into this new assembly without losing their constraints.

The above might be combined with a nested repeat region which can show an indentured BOM with the fasteners in their dummy assembly at the inner most level of indenture, then some of the components they fasten, as part of your simp rep, as the outer most level of indenture.

Obviously, you were looking for a simpler and more direct solution. But, as you will find out with Pro/e, if there's an obscure, devious, needlessly complicated and roundabout way of doing it, PTC has pioneered it and Pro/e has been its vanguard. I think they probably strained themselves patting their own backs in self congratulation.
