How to Get and Change "Default BOM Structure" by iLogic?

[ngdnam88]

Hello Everyone,

Is there any iLogic Rule can Get and Change "Default BOM Structure" of Active Part/Assembly - They're not in an Assembly!

I tried: BOMStructureEnum.kNormalBOMStructure but its gives the error. Please help me. Thanks!

Hi @ngdnam88 

Are you saying this doesn't work?

Dim oDoc As Document = ThisApplication.ActiveDocument
oDoc.ComponentDefinition.BOMStructure = BOMStructureEnum.kNormalBOMStructure

It works fine for me🤔

Hi  @JhoelForshav

I don't know why. At now it's working correct!

Thanks you very much!

Hi @JhoelForshav 

Thanks for the previous solution. I still have a problem: the first run Inventor, the rule run correctly with this rule (Assembly1 = picture 001),

but when I create a new part the rule can't run and give an error (part1 = picture 002).

Can you help me? Thanks for your time to support!

Hi @ngdnam88 

Can you share the rule that you're trying to run?

Hi @JhoelForshav 

It's a simple Code for checking Document before run another Rules,

Dim nDOC As Document = ThisApplication.ActiveDocument
MessageBox.Show(nDOC.ComponentDefinition.BOMStructure, "Checking?", MessageBoxButtons.OK, MessageBoxIcon.Information)

That rule really shouldn't fail🤔...

I cannot get it to fail on my machine, but if you have the rule locally in the document maybe try ThisDoc.Document instead?

Also I changed it to return the enum name instead of number if you're more intereseted in the name 🙂

'Dim nDOC As Document = ThisApplication.ActiveDocument
Dim nDOC As Document = ThisDoc.Document
MessageBox.Show([Enum].GetName(GetType(Inventor.BOMStructureEnum), nDOC.ComponentDefinition.BOMStructure), "Checking?", MessageBoxButtons.OK, MessageBoxIcon.Information)

Hi @JhoelForshav 

My problem with Inventor version 2018 and previous versions. with 2020 it runs correct! Both yours rules code are very good.

Any idea for me? I'm using Inventor 2018.3.8 Updated. Thanks,

It's difficult for me to figure out the problem as I don't have inventor 2018. But I'm thinking it might have something to do with the document not being saved, if it only fails on new documents?

Maybe try to save document before running the code? 🙂

Thanks @JhoelForshav 

It's happened with saved and not saved documents. I'll try to find another way to check the document. Thanks one more time!
