Alright , I'm back after a few hours to try to work on this, I have a problem with the lines in Inkscape.
when i'm making a circle or a square the lines are going both on right and left of the grid. So when i want a circle of 2.03mm (for pads) I got a circle 2.03mm large + the half of the thikness of the line . I 'd like to make it adjust to the grid do you have any solution ?
Thanks by advance .
Edit : solved by putting 0 in thikness.
