What's the difference between 'fillet' and 'chamfer'?

Question

In WIKI, I found the following:
A chamfer is a beveled edge connecting two surfaces. If the surfaces are at right angles, the chamfer will typically be symmetrical at 45 degrees. A fillet is the rounding off of an interior corner.
But if I search pictures with GOOGLE, I found both concave and convex 'fillets'.

Answer 1

A chamfer is a beveled edge that is either on the interrior or exterior of two connecting surfaces. Example

____

........\ <----Exterior

.........|

.........|





or



.....................|

.....................|

Interior -> ___/









A fillet (concave) rounds off an interior corner.

A round (convex) rounds off an exterior corner.

Answer 2

Six years old but came across this and the selected answer is incorrect.



A chamfer or fillet can be interior or exterior. A chamfer is a straight cut. A fillet uses a radius.



John's answer above is correct.

Answer 3

Chamfer is a straight line, one continuous edge, like at the end of a counter top. Fillet is a rounded edge, like an eraser.
