Fillet

A fillet is a small radius formed between the inside angle of two surfaces. Fillets are often used to help reduce stress and strengthen an inside corner. They are common on the inside corners of castings and forgings to strengthen corners and reduce stress during molding.

Round

A round is a small-radius outside corner formed between two surfaces. Rounds are used to refine sharp corners.

Sketching a one-view drawing with fillets

1. Lightly sketch the centerlines for the overall width and height of the part. Estimate overall proportions by eye, or if you know the dimensions, use a measuring scale to sketch accurately sized views. Space the enclosing rectangle equally from the margins of the sheet.
