when is a chamfer not?
at what point do you stop calling a feature a chamfer on drawings? when it is larger than 1/2", 1", more? any thoughts or a standard for this?
i think there is a world market for maybe five computers.

i am not aware of any standard that says a chamfer stops being a chamfer over a given size. we certainly call them up as chamfers whatever the size, however we may be wrong.
interesting to see what others think.
per current standards, on drawings "chamfer" is not called out anymore anyway. the correct callout would be ".10 x 45 deg" (deg symbol).

thanks ctopherfff">, i knew that. just one of those days where i couldn't see the forest for the trees.
for future reference, any angle other than 45° requires separate dims for length and angle.

just because i'm paranoid doesn't mean that they aren't out to get me.

you can say "break edge .xxx-.xxx" or "break edge .xxx max", or something like that. it doesn't mean a chamfer, can be any shape.

if you say "break edge .xxx max" you are
saying that zero is ok. if you allow no
break on the edge, that is what you will get....

i disagree. by calling an edge break it has to be broken, and you are saying it can be no larger than a certain size. not breaking it at all violates the instruction to break the edge.
