marking a corner that has been filleted on a DWG

Hi All,

I am trying to find an automated solution that updates with the drawing for the following; if I want to get the overall dimension of a part which has fillets for corners how can I switch the dimension from snapping to the fillet center to the max size? I have attached a drawing for an example. as of now I manual draw in centerlines and dimension of those as shown in the example.
