“

- In the last video, we looked at pulling out some measurements of the shortest and longest edge lengths in our gridshell. This information is really useful in our form finding process, where we'd like to explore a range of possible gridshell shapes while still keeping all the edge lengths as consistent as possible. I'm continuing right here where we left off in the example file 007 form-find-gridshell.gh. What I can also pull from these pieces of information is, you know, what is the biggest deviation that we're getting from the overall mesh. In there I'll just do a quick little expression. So double click to edit that, and then we're just going to take the absolute value of one minus x. So absolute value between one and whatever that edge length is. So that way if the edge line happens to be less than one or more than one, it shouldn't matter and we won't get a negative value, so it'll just show us the pure difference. Okay and we'll zoom in a little bit here, plug in the output…
