Drafting, Mechanical drawing, Blue prints image scaling


Still too much pain, yet enough drugs also make concentrating difficult.

I took mechanical drawing / drafting but I don’t member crap.

Can anyone point out the obvious on how to scale an image proper with a grid, to blow up said image?

Take an image 6in by 6in, break into a grid pattern, then re-draw the grid but 3ft by 3ft with same number of grid lines n a said spacing.

You then just “color” in each grid block according to the smaller image and walla, you have made a blown up copy with out any free hand.

Do I even make any sense? Not sure myself.

Can anyone help
