Materials for nested components

[Neil_Relph-Olivewoodturning]

I have a drawing of a chair and I've chosen to put the screws (eg for each seat slat) inside the same component as the seat slat, so that when the slat is copied/patterned, the screws stay with the slat. The seat slat has a material as pine, but when I've inserted the screw (from the Traceparts library, as a component), the material type for the slat gets removed in the BOM). I'm not sure this is correct - is it? I suppose I could make the slat a component inside another "slat" component, but logicaly to me, the screws are part of the top level slat.

Attached is the pdf of the BOM as it works now, with blanks for the material against the slats.

I believe the best way for you to do what you desire is by making each slat component and screw component(s) a sub-assembly under your top level.  Then it will report correctly to the Parts list.  The screw(s) will be held into the slat by Joints and will move as one component.  The Screencast will explain my idea.  Model I used is attached, you can create the drawing to test it.

John,

Thanks for the reply. I've attached two versions of my model, one with the screws inside the slat and one with both the slat and the screws at the same "level" inside a new component called "Slats". Whilst the second one gives the best representation of this inside the BOM, it's not intuitive from a construction point of view. I would normally create a slat, put the holes in it and then pattern it to have all the slats i need. Then I'd put 4 screws in each slat, inside the same component so that the screws also get patterned, too. This is because if you were drawing like you constructed the item, you'd make all the eat slats first and place them and screw them in after that.

Doing it the second way means you have to put the slat and the 4 screws inside an assembly and then pattern the whole assembly, which seems a lot less logical from a furniture manufacture point of view. 

I've  also posted two pdfs of the respective BOMS from the models

@jodom4   From the furniture livestream this week, do you have any tips?

If you want to place the screws into each slat as a unit, and you want the BOM to show both materials, then you will have to use the method of Sub-Assembly, slat as a component and screws as components.  This is the method I outlined earlier and what you call the second method.  

There is an alternative, you can create a drawing that will call out the slat assemblies and then create a second detail sheet to call out the parts list for ONE slat assembly.  This will get you the best of both worlds.  Below are screen capture of sheet 1 and sheet 2 of the same 2D drawing.

John,

Many thanks for your help. Ive marked your solution as "accepted" because I think you've given me a solution which is the best compromise. Ideally, I'd like more, such as the ability to capture total number of 4x50 screws in the whole chair and the materials listed against one, top level BOM. I'll set up a new drawing with just slats in and play around with the options and if I find a better solution than yours (I doubt it), I'll post it back.

I was hoping that I could make some plans like chair and give the plan away free, but to do so, I'd need to make the plans "idiot proof". I think I may need to export the BOM to a csv and do some work outside of Fusion to achieve what I want.
