Having an error while creating a part list in a drawing for a pattern mirror assembly

sdesaulniers5K8HT — Wed, 01 Oct 2025 12:25:08 GMT

Hello,

I'm trying to do a drawing of a pattern mirror assembly. I have an error while creating the part list.

"Request Set BOM View Properties cannot be run on document ...". I tried to enable BOM directly in "Assembly" -> "Bill of Materials" and I have the same error. I'm using Inventor 2026.

Hi!

Can you share the model or post some prints from the BOM and the error?

Here some screen shot :

Thank you for the screens.

I guess is related to the model states in part ...DPL-03...

Do you really need model states in this part? If not, try to delete them and stick only with the primary model state. (it's only a guess by checking the prints...)

I have the same problem.

I have also have this error when I try to save the mirror assembly :

Can you share the model here to try on my PC?

Only this sub assembly, not the entire model where is in....

Another shot in the dark... it's possible this files are in a project library folder? Or in a folder without write permissions?

Sorry, I cannot share it with you.

You can reproduce the error with a quick pattern mirror assembly and try to enable the BOM.

I just did that and have the same result.

Ok... i get what you mean...

It's probably a bug to be fixed...

You should Report it.

Thanks for taking the time

If I use your assembly. The problem happens when I try to do a standalone drawing of camValveIT_MIR not the assembly containing the mirror pattern.

With my assembly, I have the same result has you.

When I try to do a drawing of A-Test-G2-MIR alone it's not working.

Yes... after analyse better your screens, i tried the mirrored assembly alone, and i got the same error.

@johnsonshiue , this is already reported?

Hi @sdesaulniers5K8HT,

The behavior does not look right to me. I tried a simple assembly but I cannot reproduce the behavior. Please share the files in zip with me directly at johnson.shiue@autodesk.com. I would like to understand the PartsList error better.

Many thanks!

Hi @johnsonshiue , Maybe you made the same mistake as me... the problem happens when we open only the mirrored model.

Check the video:

Hi Folks,

Yes, the issue is reproducible within the mirrored assembly. The mirrored assembly is like a child of the mirror source assembly. The editability is limited, since it is driven by the mirror source assembly. To get the proper BOM table, you may place the mirrored assembly in a new assembly. Or use the top-level assembly (Model States:Suppress or Design View:Invisible) to get the corresponding PartsList in the drawing.

Many thanks!

So, in resume...

1- Selecting Mirror pattern - If you choose mirror Pattern mode, you cannot edit the mirrored part later, will will have to be equal (mirrored or not) to the source, and the mirrored part positioning will be associative with the source position
2- Selecting Flat structure - If you need to mirror a part and do some modifications later. The positioning is not associative with the source.

I do not find this to be a great solution. In an update it would be way better if when I mirror a assembly it behaves like an assembly so I can use it in drawings and not have to go through a crazy process.
