Custom SheetFormat "Doesn't Exist" Within My Code

[MechMachineMan]

So As the title says, in one drawing I made a custom sheet format (by right clicking a sheet name) then saved this as a document template.

I'm making a code to automate drawing creations, and in this I must change sheet formats so that the sheets don't look like crap.

Anyways, in doing so, my code with recognize and function properly if I use anyone of the default sheet formats, but fails if I use mine.

There last 2 lines of the error that it keeps throwing is:

System.ArgumentException: The parameter is incorrect. (Exception from HRESULT: 0x80070057 (E_INVALIDARG))
at System.RuntimeType.ForwardCallToInvokeMember(String memberName, BindingFlags flags, Object target, Int32[] aWrapperTypes, MessageData& msgData)

Now, I have read somewhere that this error appears when the file cannot be found in memory, or is having memory issues. This leads to believe that the code doesn't think it exists. However, when I go create a file with my template file, it clearly does.

Any help would be appreciated! Thanks!

Private Sub CreateDwgDoc(oModelName As String, oDrawingDoc As DrawingDocument)

Dim oModel As Document
Dim oDocs As Documents = ThisApplication.Documents
Dim oFormat As SheetFormat


     oModel= oDocs.ItemByName(oModelName)   
    
     oFormat = oDrawingDoc.SheetFormats.Item(7)
    
     oDrawingDoc.Activate

     oDrawingDoc.Sheets.AddUsingSheetFormat(oFormat, oModel, "Shee",,,)

Well. I figured it out.

My SheetFormat I was copying and trying to use didn't have model views placed in it, whereas mine did. And my code was for a sheet format that had a model in (as indicated by the oModel argument present.)

The fix was simply to remove oModel.
Alternatively, I could have just used a view in my sheet format.
