Offset inwards

I have a broblem offseting my curves in the same direction. Given they have different vector in rhino, how can i make all my closed curves offsets inwards instead of some offseting from inside and some from outside. I want to solve it in GH.

Ok i think i solved my issue. I am sure there are different complexities regarding offset sides but my Π like polylines get offseted inwards with this script. In case there is a simpler way to do it, this is what i have come up with:

(Again thanks both for your help)

I ran into a similar issue, except that all of my edges are curves, including several with reversing curves. after a long time of hitting my head on it, i used a sequence of a) offset b) shatterint c) tree filtering d) join. had to pay alot of attention to tree structure, to make sure that each element matched properly to its proper place in tree hierarchy, 2+ weeks on that issue, but it worked out and the project is now on the mill.
