I am fairly new to grasshopper. I have created this curved wall, and have divided the surface and offset these surface crvs. Now that I have offset these crvs, I am wondering if there is a way for me to select the outside edge of each of these new boundary surfaces. I tried to draw what I am trying to do. Thanks.
I suppose you have identified all the rectangles in a separated list. Once you have located all the rectangle surfaces you can debrep them, locate the mid point of the 4 lines which compose the rectangle and filter the curve through the distance between the mid points and the surface using sort command.
