I am using Inkscape to trace some model airplane plans and cut out balsa with a Sizzix. It would be great if there was a simple way to make all the crossgrain cuts separate from the cuts that go with the grain. Once I have say an wing rib done in the trace it cuts out okay but there is some inaccuracy trying to make 90 degree corners. How can I make all the cross grain on a separate layer? It is easiest to draw the wing rib as one drawing but I would need to break it apart and put either end of the rib as a different layer. Thanks
