XCS 2.0 Node Tutorial Easy - incl. Test Grid

for easy copying and you can open the file in XCS and try it yourself
the advantage is that the color with which you use the vector tool is different from that of the grid so that you can see what you have created 

in the settings you can turn off the function that the vector tool always aligns itself this helps in some situations - auto snapping 

I have created 2 pictures with the AI to show how to use the trace image function and what you can do if this function is not usable

you always have to play with the sliders frame by frame 
until you have found the right setting

as soon as the picture is finished you have to ungroup it 
and then you can remove the things you don't need anymore

sometimes it is not possible to trace a picture
then there is the vector method
simply trace the lines

the practical thing is that you can still edit the nodes afterwards
you can then change it with your own ideas
