Describe the function of grid lines, including recommended grid line spacing and give an example of the general note placed on a drawing to identify the grid lines used.
What will be an ideal response?
Grid lines are a pattern of thin equally spaced perpendicular lines drawn at an exact scale across the face of the drawing to confirm dimensional accuracy. Grid lines should be placed on their own layer. The grid spacing depends on the size of the drawing, but common spacing is 5.000 in. (127 mm) or 10.000 in. (254 mm). A note is placed on the drawing identifying the grid line spacing, such as GRID LINES 5.000 (127 mm) ON CENTER.
