Insert virtual component and renumber BOM

[breinkemeyer]

I have an assembly of a screw conveyor.  Our drafting department wants the first line of the bom to be the Entire assembly as a virtual component, renamed to Item A and renumber the remaining lines starting at Item 2 sequentially starting with item number 1.  I'm not sure of a couple of arguments needed for the methods (see attachment).

here is the code

// add the virtual components to the list
AssemblyDocument oDoc = (AssemblyDocument)oInventorApp.ActiveDocument;
AssemblyComponentDefinition oCompDef = oDoc.ComponentDefinition;

Matrix oMatrix = oInventorApp.TransientGeometry.CreateMatrix();
ComponentOccurrence oNewOcc = oCompDef.Occurrences.AddVirtual("SC-18", oMatrix);
VirtualComponentDefinition oVurtCompDef = (VirtualComponentDefinition)oNewOcc.Definition;
oVurtCompDef.PropertySets["Design Tracking Properties"]["Description"].Value = "MTO Screw Conveyor";

BOM oBOMDef = oDoc.ComponentDefinition.BOM;
oBOMDef.StructuredViewFirstLevelOnly = true;
oBOMDef.StructuredViewEnabled = true;
oBOMDef.SetPartNumberMergeSettings(false);
BOMView oView = oBOMDef.BOMViews["Structured"];

oView.Renumber(1, 1, );

oDoc.Save();
oDoc.Close();

Ok, an update.  I was able to get the conveyor itself in the bom as the first item (virtual part).  now I just need to renumber the bom 

oView.Renumber(1, 1, ) the third variable is an object of the bom lines to renumber.  what object is it looking for?

It is BOMRows collection:
