It just works with some letters, i don't get the order it follows when i add the elements to the array, coord.append(x) coord.append(y). Sometimes the x points shift and it mess everything again.

Hey, i'm trying to create a grid of lines that whenever intersect a font (shape) they get thicker. The rough sketch looks like this:
I haven't found a better way to get intersection points with open paths ( https://github.com/typemytype/drawbot/issues/160 )
and i'm doing everything by hand.

Is there a better way to do it? If i were to continue like this at a certain point everything will mess up:

In this case the points are in the right positions, but the lines should be horizontal and it's driving me crazy.
