Yesterday I had resorted to the following code: LElementTotal = lGraphicElementTotal + lNonGraphicElementTotalĭebug.Print vbNewLine & vbTab & "Total Models: " & lModelTotalĭebug.Print vbTab & "Total Elements: " & lElementTotalĭebug.Print vbTab & vbTab & "NonGraphical Element Count: " & lNonGraphicElementTotalĭebug.Print vbTab & vbTab & "Graphical Element Count: " & lGraphicElementTotal & vbNewLine LNonGraphicElementTotal = lNonGraphicElementTotal + lNonGraphicElementCount LGraphicElementTotal = lGraphicElementTotal + lGraphicElementCount LNonGraphicElementCount = ĭebug.Print vbTab & "Model: " & oModel.name & ", Graphical Elements: " & lGraphicElementCount & ", NonGraphical Elements: " & lNonGraphicElementCount Set oDgn = OpenDesignFileForProgram(sFileSpec, False)ĭim lGraphicElementCount As Long, lGraphicElementTotal As Longĭim lNonGraphicElementCount As Long, lNonGraphicElementTotal As Longĭim lModelTotal As Long, lElementTotal As Longĭebug.Print "Design File: " & oDgn.FullName & ", NonModelCacheCount: " & & vbNewLine Here is a sample:Įnd Sub Sub DgnFileGraphicElementCount(sFileSpec As String) Dim oDgn As DesignFile A way to accomplish this with less overhead would be to query the Graphical and Non Graphical Element caches.
