Diagonal line method
A diagonal line must be drawn through the area that you wish to edit.
Put the command sheet on top of the original.
Draw a line using a felt tip pen (black, red or blue) with a thickness of at least 1mm.
Make sure there is no break in the line.
The diagonal line can be drawn from left to right or vice versa.
Draw the line at least 2mm (0.08 inches), away from the image so that the whole image can be recognized.
a, b, c, d = 2mm (0.08 inches)
The line marking the designated area should be more than 2mm (0.08 inches), from any neighboring image.
a, b, c = 2mm (0.08 inches)
