The above code appears to create a "View" or ViewTableRecord.

After execution, this view is not listed in AutoCAD as a view that is made available to the user.

I fixed this by using the "AddNewlyCreatedObjedt" method of the Transactionmanager after adding the viewtablerecord to the viewtable.

The topic is old but I'm trying to do something similar and when i do as in your example:
aAcadViewTable.Add(oAcadViewTableRecord)
i get "eLockViolation" exception.

Application.DocumentManager.MdiActiveDocument.LockDocument()
The solution !!!
