I have a pattern that i want to cut it in laser cutter. I need to offset my lines for that. I would like the offset to depend on attractors. So i attach my file so that maybe someone can help me.

 Inside the file there are these notes:

i want to offset the lines so that they
can be cut by a laser cutter.
the offset command doesnt help me
though because it doesnt connect
the lines since i cant fillet, PLUS i want
to offset with multiple attractors.
So I though I could move the
start-end points in the direction
of the bisector of each vertex
that is formed by each pair of lines
and finish with a line command
as i did in the previous step
where i prepared the deformation
of the pattern.

I tried shift list command but i
see that its not right because
if i shift my list then its not sure
that gh will pick the
neighbouring line, so it could
connect random points
sometimes. I cant think how
to manage my lists or something
so that i take the bisector
each time from each vertex
in order to move each vertex
in the direction of the bisector
and then connect start-end points
with the line command.
