When creating a fillet/chamfer sometimes the command can't complete because there isn't enough material to fit the feature in. For instance, you type 5mm rad and there's only room for a 4mm fillet.
I'm asking for a maximum option so Inventor calculates the maximum fillet it can fit in and creates that instead of having to use trial and error.
This could just be a tick box to say, create max rad, or something.
