Export main assembly to RFA file using iLogic

Looking for help with iLogic to export main iam assembly to RFA.

Found this thread, but this code exports all the individual components and not the whole assembly.

Hi @frahaman7SKBG. I haven't tested this yet, so be careful, because I don't use BIM stuff. But in theory the following simpler iLogic code should work for you if you just want to export the main assembly. It simply captures the currently 'active' assembly document, then uses the same path and file name as that assembly, but with the ".rfa" file extension when exporting the rfa file. If you need to change the path or file name further, you can change the line defining oFFN, or use multiple more lines to manipulate the string (text).

If ThisApplication.ActiveDocumentType <> DocumentTypeEnum.kAssemblyDocumentObject Then MsgBox("An Assembly Document must be active for this rule to work. Exiting.",vbOKOnly+vbCritical, "WRONG DOCUMENT TYPE") Exit Sub End If 'gets the 'active' assembly document Dim oADoc As AssemblyDocument = ThisApplication.ActiveDocument Dim oADef As AssemblyComponentDefinition = oADoc.ComponentDefinition 'same path & file name as active assembly, but with ".rfa" file extension Dim oFFN As String = System.IO.Path.ChangeExtension(oADoc.FullFileName, ".rfa") 'export oADef.BIMComponent.ExportBuildingComponent(oFFN)

This is great, would you be able to do this with automation for batch updating OmniClass and Family Type Names of models and assemblies?
