HRESULT 0x80004005 (E_FAIL) when running iLogic rule on BeforeSave event

[Anonymous]

I have a rule that used to work just fine in Inventor 2017 Professionnal that no longer works in Inventor 2019 & Inventor 2020.

The rule code is the following:

Dim oAsmCompDef As AssemblyComponentDefinition
oAsmCompDef = ThisApplication.ActiveDocument.ComponentDefinition

oAsmCompDef.RepresentationsManager.LevelOfDetailRepresentations.Item("SUPPRESS_INVISIBLE_ITEMS").Activate(True)

I tested this with attached Assembly2.iam file, when hitting the save button I get the following error:

Error in rule: Rule1, in document: Assembly2.iam

Erreur non spécifiée (Exception from HRESULT: 0x80004005 (E_FAIL))

Stack trace:

System.Runtime.InteropServices.COMException (0x80004005): Erreur non spécifiée (Exception from HRESULT: 0x80004005 (E_FAIL))
   at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)
   at Inventor.LevelOfDetailRepresentation.Activate(Boolean SkipDocumentSave)
   at ThisRule.Main()
   at Autodesk.iLogic.Exec.AppDomExec.ExecRuleInAssembly(Assembly assem)
   at iLogic.RuleEvalContainer.ExecRuleEval(String execRule)

This is an upgrade error from 2017 to 2019, so I would expect to get support from Autodesk.

Hi,

Since the LOD is not available in the assembly you need to add it first.

Dim oAsmCompDef As AssemblyComponentDefinition
oAsmCompDef = ThisApplication.ActiveDocument.ComponentDefinition

Try
	
oAsmCompDef.RepresentationsManager.LevelOfDetailRepresentations.Add("SUPPRESS_INVISIBLE_ITEMS")

Catch 
	

	oAsmCompDef.RepresentationsManager.LevelOfDetailRepresentations.Item("SUPPRESS_INVISIBLE_ITEMS").Activate(True)
	End Try
