CORNER RADIUS FAIL

Hi All,

Just simple question in regards to MOI handling Corner fillet radius - if you take a square 50x50mm outline and apply a 25mm radius it fails unless you go under 24.99 is OK why is this the case with fillets when in RHINO a full 25mm radius fillet can be applied only leaving the one shared control point?

Just wondering if its a scale tolerance issue
