XD. I made this for Plain Geometry class on university. A simple geometric analysis and construction of DA's logotipe. It gone 100% well and the measures are real! You can test it... it WILL work
DA logo is (c) to DeviantART - used without permission. But i know they'll let me use it this time ^^'
edit: now putting it in Tutorials and Resources for anyone willing to use it to do it without fear XD. Just give credits to me and DA and everything will be OK
edit2: after years someone found the mistake in the measures! So i'm finally editing it. ^^ Of course there is some diference with my rulers and yours so we can call each measure from 0,2mm to 1,2mm of deviation from the original. Thanks Threchette!
