Wrong quantity in BOM (parts only)

[Anonymous]

I have a problem with Bill of materials (parts only).

I use one part in many assemblies. In "parts only" section of BOM in main assembly I wish to see total quantity of this part. Instead I see the same part twice.

Structure looks like this:

-Main assembly

    -Beam A

        -Pipe (4pcs)

    -Beam B

        -Pipe (4pcs)

BOM shows the same part twice, where both have quantity 4pcs, instead of showing it only once with quantity 8pcs.

I DO NOT use LOD nor Representations.

I tried to open this project on different computer - no change.

This affects many parts - not just one.

At the top of your screen shot there is a button for "Part Number Row Merge Settings" is that turned on?

I'd also check the BOM structure setting of your parts and subassemblies:

Turning "Part Number Row Merge Settings" on and off makes no difference. As I mentioned, this is the same file.

I don't use parts other than "Normal" (no phantoms, references etc.)

Is this box checked in the row merge settings?

As I said before - turning this box on and off makes no change. And of course I tried.

This option (Enable row merge on part number match) will merge together different files (different parts) with the same part number. My case is different - I have a problem with merging the same file - a part which appears in many assemblies.

hi,

are that model create from frame generator? if yes, check Part Number & G_L in custom iProperties, are same value?

[Anonymous]

No. I don't use frame generator.

This part also don't have anything to do with Content Center.

It is impossible that iProperties have different values because it is the same file - for example it is Pipe.ipt.

This file Pipe.ipt is used in two assemblies.

Hi there Tomasz

I was wondering if you ever found a solution to this, as I have EXACTLY the same problem?

Many thanks

No I did not.

But I've found some workaround.

Just edit this part, you have problem with. Add a chamfer, a hole or whatever that will change the mass. Then save it.

Later you can remove what you just added.

In my case it helped, but still I don't know why this problem occured.

Hello again

I did as you suggested and modified the part (tried in several different ways), but unfortunately this doesn't help in my case.

Thanks anyway

Stephen
