Challenge 220 is done! Went for as few tools as possible, managed to get it down to 9 tools eventually, so thankful to the spatial functions available in the formula tool!
(included a text input for reference table to create the fields)
I admit defeat. As @TonyA I tried several approaches to avoid any hard-coding, but was trumped by some of the irregular shapes.
So I went with an input text with the vertices as others have done.
I reuse some of the tools I created while trying the not-hard-coding... not all was lost.
Great question. I assume you mean how to dynamically define the points that make up each field, and how to get them in order to make a proper polygon I did not solve that one either, although I think the text input I used is a bit cleaner than what you did.
After that, though, my solution is dynamic (attached). Messy - I'm sure there's a better way to compute hedge length than what I did.
