Describe the practice for representing a sheet metal part with only the flat pattern, and using rectangular coordinate dimensioning without dimension lines.
What will be an ideal response?
A common method for representing a sheet metal part is only the flat pattern, and using rectangular coordinate dimensioning without dimension lines. The flat pattern dimensions take into consideration material bending so the final bent part is exactly as designed. For example, a flat pattern drawing of a sheet metal part dimensioned using rectangular coordinate dimensioning without dimension lines. In this example, leader lines and specific notes dimension circular features. The drawings also show centerlines for bend lines with text or arrow indicating the bend direction.
