+                      <p>But designing in 3D still is hard for me, even if these programs are easy to use, as I'm easily lost in the 3-dimensions spaces !</p>

                       <p>For Inkscape, I'm used to Illustrator so it's really hard for me to like this program but I'm getting used to it and some functions, like vectorize a bitmap image or preparing an embroidery file, are well done. But my heart is still balancing on Illustrator's side !</p>

                       <p>UPDATE : it was given as advice that it could come frome the "ESP32 chip" and "licence". I will search for that and hopefully be able to use and understand all it correctly as I will need that for my final project !</p>
