Can anyone help by providing a VBA script to to change the Level of display for an assembly AND ALL its sub-asseemblies automatically to an LOD that I called ilogic when opening the file.

I am running Inventor 2011 and I need this as it is creating some problems with the ilogic rules when they run....


Thanks for your help

Here is some .NET code. You will have to convert it to VBA. LOD works kind of funny from what I can tell. You must first set the LOD of the top assy and all sub-assy's and save the model. All my attempts to set the individual sub-assy's LOD result in an Inventor application crash.



        Dim oMyDoc As Inventor.AssemblyDocument
        oMyDoc = invApp.ActiveDocument

        ' Set the Level Of Detail...
        Dim oRepMgr As Inventor.RepresentationsManager
        oRepMgr = oMyDoc.ComponentDefinition.RepresentationsManager

        Dim oMasterLOD As Inventor.LevelOfDetailRepresentation
        oMasterLOD = oRepMgr.LevelOfDetailRepresentations.Item('iLogic")

Also, here is an iLogic rule that I place in the sub assemblies that require component suppression


Sub SetLOD(ByVal myLOD As String)
	ThisApplication = InventorVb.Application
	oMyDoc = ThisDoc.ModelDocument
	' Set the LOD to Master
	Dim oRepMgr As RepresentationsManager
    oRepMgr = oMyDoc.ComponentDefinition.RepresentationsManager

    Dim oMasterLOD As LevelOfDetailRepresentation
    oMasterLOD = oRepMgr.LevelOfDetailRepresentations.Item(myLOD)

	RuleParametersOutput() ' use this before DocumentUpdate
	InventorVb.DocumentUpdate() ' Update now
End Sub

For iLogic Code to change the LoD I use the following (which is of course still VB , but it runs inside of an ilogic rule!)




'''We need to make sure the LOD is set correctly : 


'''Side note

'''Public Enum LevelOfDetailEnum
''' kMasterLevelOfDetail = 56065

'''kAllComponentsSuppressedLevelOfDetail = 56066
'''kAllPartsSuppressedLevelOfDetail = 56067

'''kAllContentSuppressedLevelOfDetail = 56068
'''kSandboxLevelOfDetail = 56069

'''kTransientLevelOfDetail = 56070
'''kSubstituteLevelOfDetail = 56071

'''kCustomLevelOfDetail = 56072
'''kLastActiveLevelOfDetail = 56073

'''End Enum

Dim doc as AssemblyDocument = ThisDoc.Document

If doc.ComponentDefinition.RepresentationsManager.ActiveLevelOfDetailRepresentation.LevelOfDetail <> 56072 'LevelOfDetailEnum.kMasterLevelOfDetail Then

Dim oLOD As LevelOfDetailRepresentation

Dim oAsmCompDef As ComponentDefinition

oAsmCompDef = doc.ComponentDefinition

oLOD = oAsmCompDef.RepresentationsManager.LevelOfDetailRepresentations.Item("ilogic")


End If

That will change the main level of detail, but I'm sure you could throw it into the rules of your subassemblies and get similar results (maybe :smileysad: ). Use triggers to make it run on document open!
