A good drawing should include material, material thickness, finishes, tolerances, revisions and any hardware call outs. It will display a face view and/or top view, plus any additional views of the side(s) or the edge. Hidden lines should also be included in the drawing. A hidden line is the dotted line on a drawing that shows where a bend is. The edges of the drawing are solid lines.
It is pointless and discouraged to submit a drawing that displays a flat view that is going to get bent. All companies have different bend allowances and the flat drawing cannot give an exact length, unless the engineer makes each drawing for each manufacturer. The manufacturer has to consider what their bend tolerance is, K-Factor, to make the part. The K-Factor is the amount the metal will stretch when it is bent.
