Here is my problem. I have 4 solids (That are beams). I exploded them with the outcome to choose only the surfaces marked in image 1. After exploding them dynamo create 4 lists with the surfaces. The problem is that dynamo put the surfaces of each list in in different order. For example in the beam showed in Imagine 2 the indexes of the surfaces that I need are 0 and 5 but in beam showed in Image 3 the indexes of the surfaces that I need are 2 and 3. Is there any way to re-order the sub-list so the surfaces in all the list follow the same index order?
