Why does solidworks not have a good way to verify that holes are concentric?  Yes yes, they have the 'hole alignment' tool in assemblies but it is not accessible through the API (at least in 2013).  Also, they have no sensors that will work to accomplish this goal.  This leaves me with two options: put holes in context (evil, evil, evil) or mate every hole concentric (probably evil, evil evil).

Has anyone else come up with a way to tackle this problem?
