QTY in Bill of Materials Table

[78finn]

I have an assembly I'm working on for a product. The product can be used in either right / left orientation, but is symetircal, so no need to draw/document left/right handed versions.

But for ordering a complete set my Bill of Materials table needs to show double QTY's of each part.

The easy fix is to add twice the number of parts into the original assembly and hide the duplicates so that the B.O.M shows twice the parts but the drawing doesn't show duplicates.

This is messy and seems unnecessary though.

Does anyone know of a way of tweaking the B.O.M table so that all part QTY's are doubled?

Its easy in Solidworks, you just type in x2 and it doubles the numbers. Whats to do in Pro Engineer?

You could add a relation to the repeat region for the quantity. Typically, the BOM should only list what is required for one complete assembly.

Hi there kdem,

Thanks for the response...

I have been looking into adding a repeat region, but it appears you have to do it for every part i.e. you can't just apply a relation to the table/B.O.M. So I would need to go down the table and alter every single part QTY individually.

Is that what you meant? Or is there away of being able to add a relation as a general rule/setting to the B.O.M that subsequently effects all part QTY's?

As kdem said, you dont need to double qty. Because at a time you are showing either left or right version.You can specify note about that.If you double the quantity some1 would misinterprete that.

You can also use "Included" parts to the assembly. They show up in the BOM but are not displayed and require no assembly constraints.

Srieger: thanks for the replay...where in Pro Eng can I find this option? Does it work if the part is already included in the Bill of materials?

s_pme20: A note is ok, but notes get missed all the time and for large scale production it is far safer to have the B.O.M showing what is actually required. If the B.O.M does not show the 'correct' QTY...even if there is a note to say '1 set shown - 2 sets required'...its leaving it open for a mistake to be made. Most of my parts get made in China...and its much safer to just show the correct QTY by the part number...minimal risk of things being lost in translation.

Sorry I didn't reply earlier but if you still want to try here are some directions. You create a repeat region for the assembly and one of the menu selections under the Repeat Region selection should be relations. Select that and ProE will ask to select a repeat region. You then create a region parameter and relation for the total quantity of for each item listed in the BOM (ie total_qty=2*rpt_qty). You can then replace the rpt_qty with total_qty and the BOM should display 2X the quantity of each item (using the example relation) in the BOM. You also might want to create two columns, one for rpt_qty and one for total_qty, so you can show what is needed to create one complete assembly and the total number of each item you need to order for multiple assemblies.

Hi there kdem,

The parameter in my BOM is: &rpt.qty

adding a repeat region/relation i.e. total_qty=2*rpt_qty or total_qty=2*rpt.qty

doesn't seem to work.

I'm obviously doing something wrong here.

Any ideas?

Going back to the original post, as I understand the Right
Hand and Left hand configurations are NOT Mirrored
components. If they are, then they are different and
require different part numbers. Cannot be multiplied.
In case they are identical and is used TWICE, then...
Draw the complete assembly, Show only partial view of the
assembly.
Your bill will still list all the components multiplied
twice.

In the assembly go to Insert, Component, Include. Yes, it works if it's already in the bill. It simply adds the part to the model as a packaged component that is not displayed.

Replace the parameter &rpt.qty with &rpt.rel.total_qty in your repeat region

Dross: Thanks worked perfectly! Thanks so much for the help!

Srieger: I think this is actually a really nice clean solution as then the assembly is reflective of the drawing i.e. when someone else comes to look at my files they are able to see that I have included the parts in the assembly.

Thanks to everyone that posted on here....two really good solutions!

hi guys,
what is meant by parametric BOM in proe. how it is created.
any one pl's explain. iam waiting for ur reply.

thanks in advance.

@karthi.j: plz open it as new topic under drawing forum.
one advise: how to put parametric BOM is very broad question.I recommend to read some basic
