[Using AutoCAD Mechanical 2005]: Is it possible to ADD a BOM item to the ACADM BOM with VBA? All I want to do is add items to the (MAIN) BOM. I don't have any part references to relate them to, just entries in the BOM table. For some reason I am unable to do this! Dim oSymBBMgr As SymBBAuto.McadSymbolBBMgr Dim oBOMMgr As SymBBAuto.McadBOMMgr Dim oBOM As SymBBAuto.McadBOM Dim oBOMItem As SymBBAuto.McadBOMItem Dim oTarget As AutoCAD.AcadBlock Set oSymBBMgr = MyDwg.Application.GetInterfaceObject("SymBBAuto.McadSymbolBBMgr") Set oBOMMgr = oSymBBMgr.BOMMgr Set oTarget = ThisDrawing.ModelSpace Set oBOM = oBOMMgr.GetBOMTable(oTarget, "MAIN") Set oBOMItem = oBOM.AddUnassociatedItem("2", 3) thanks, Jim Shipley
