Expanding boundaries to evenly fill space

Yes! If I were to draw this ye olde fashioned way with pen and paper, this is probably the approach I would have gone with.

I’m without Rhino access for the next few days but will test my far inferior knowledge then and get back to you. When I first looked at the image I wondered if there was a method of shattering each line at its intersections and then keeping just the longest segment, effectively removing the redundant end pieces, but this may not work where a line has an intersection at the middle. Removing the two shortest ends instead may be an option? I’ll test this approach anyway in the absence of someone more talented. :laughing:
