How to draw lines and drill holes for anti-theft net
Make a metaphor:
Draw the center line: drill a square tube with a total length of 1200MM, with a hole diameter of 22MM, drill 10 gadolinium and a gap of 1 1 grid.
1200 length +22 aperture =1222/1=11
The first line is11-11(that is, half the aperture of 22, because it is the first one, it only occupies half the hole), the second line is+1 1, and the third line is.
Buy a calculator that can be added continuously. It is convenient to draw lines.
