well i just start working on glyhps, used to work with ‘fontographer 5’,
there i used the ‘knife tool’ to open paths, but it seems that all that the knife do in ‘glyhps’ is to add new nodes to the shape, and dont making an ‘open cut’.
im sure there’s a basic solution for that, but you wouldnt know, i spent too much time figuring it out alone, im clueless.
