Here is another tip with your G
When you press the zoom button and tap 4 times i.e the max. as far as zoom can go - the squares match up exactly to scale. You can then take a ruler and measure up against the figure. This is very helpful while designing.
You can measure for eg how much of a image gets overlapped in welding or you can measure the height or sides of a triangle, octagon or hexagon without the need to whip out your calculator and ruffling through those complicated :) (this coming from an engineer - well look how far I've fallen into this art world) mathematical formulas.
Ok - a question here to you all (if any of you are here ie :) )
Are any of you really reading my blog? I don't see any comments so don't know if I'm passing on useful info.. Should I continue posting? I don't want to write to myself. I would much rather paint
