Calling AssemblyComponentDefinition.AnalyzeInterference Method can crash Inventor even when used within Try Catch

[Maxim-CADman77]

AssemblyComponentDefinition.AnalyzeInterference method crashes Inventor if called for collection of occurrences that includes at least one unresolved ... even when used within Try-Catch block!

The issue can be reproduced on any assembly with at leas one unresolved component with iLogic like:

If Not TypeOf ThisDoc.Document Is AssemblyDocument Then MsgBox("Return",, iLogicVB.RuleName) : Return

Dim aDoc As AssemblyDocument = ThisDoc.Document
Dim acd As ComponentDefinition = aDoc.ComponentDefinition

Dim oTOs As TransientObjects = ThisApplication.TransientObjects

Dim occCol As ObjectCollection = oTOs.CreateObjectCollection

For Each occ In acd.Occurrences
	' co.ReferencedDocumentDescriptor.ReferenceMissing Then Continue For
	occCol.Add(occ)
Next

Try
	acd.AnalyzeInterference(occCol)
Catch ex As Exception
	MsgBox("Fail:" & vbLf & ex.Message,, iLogicVB.RuleName)
End Try

MsgBox("Success",, iLogicVB.RuleName)

Dear @MjDeck could you, please, study this?

Hi,

try replacing

Dim acd As ComponentDefinition = aDoc.ComponentDefinition

with

Dim acd as AssemblyComponentDefinition = aDoc.ComponentDefinition

you can optionally add this to chek your test

Dim res As InterferenceResults = acd.AnalyzeInterference(occCol)
MsgBox ( res.count)

Hi Maxim - thanks for reporting this. I created internal issue INVGEN-76860 for it. I think we can fix it soon.
