BOM.GetPartNumberMergeSettings2

[ThomasRambach]

Whenever I use the following:

Inventor.AssemblyDocument ASMdoc = (Inventor.AssemblyDocument)mDoc;
AssemblyComponentDefinition oAsmCompDef = ASMdoc.ComponentDefinition;

oAsmCompDef.BOM.GetPartNumberMergeSettings2(out bool boolMergeEnabled, out string[] strMergeExcludeList, out bool boolMergeInstanceRows);

It always results in an error with GetPartNumberMergeSettings2 like: 

System.NullReferenceException: 'Object reference not set to an instance of an object.'

I'm not sure why this is. It's a normal Inventor assembly file each time. What am I doing wrong?

Hi @ThomasRambach ,

Maybe you're not setting the string array?

This runs without error

Dim ASMdoc As AssemblyDocument = ThisApplication.ActiveDocument
Dim oAsmCompDef As ComponentDefinition = ASMdoc.ComponentDefinition

Dim strings = New String() {"1111", "2222" }

oAsmCompDef.BOM.GetPartNumberMergeSettings2(True, strings, False)

{
    AssemblyDocument ASMdoc = Inventor.ActiveDocument;
    ComponentDefinition oAsmCompDef = ASMdoc.ComponentDefinition;

    var strings = new string[] { "1111", "2222" };

    oAsmCompDef.BOM.GetPartNumberMergeSettings2(true, strings, false);
}

@Curtis_Waguespack  Wouldn't that only be needed if I'm "Setting" and not "Getting"? It's always looking for the the "Out" on Get.

Ahhh, I think you're right. I only took a quick look at this earlier. I'll try to have another look later.

@ThomasRambach,

The C# code sample for GetPartNumberMergeSettings2 API method is as below:

AssemblyDocument oDoc =(AssemblyDocument) m_inventorApp.ActiveDocument;

AssemblyComponentDefinition oDef = oDoc.ComponentDefinition;
BOM oBom = oDef.BOM;

bool bMerged = false;
string[] sExcludeList = new string[] { };
bool bMergeInsRows = false;

oBom.GetPartNumberMergeSettings2(out bMerged, out sExcludeList,out bMergeInsRows);


Thanks and regards,
