Hi Guys, I’ve very recently picked up python. I’m trying to create a python code that tells me to distance from a curve to a point. I think I have done this so far, however it only does it for each index. Forr Example: 0 to 0 1 to 1 2 to 2 When I need to it to tell me the distance for every curve to every start point. For example: 0 to 0 0 to 1 0 to 2 1 to 0 1 to 1 1 to 2 If this was a node I could just change the lacing, however as I’m doing in python it’s not that simple to me. [Python Text Link](https://paste.ofcode.org/h3xjRpJmaKYJrwqi5eiLWW) The node set-up ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/e/d/eda854d44cbd86c2f5f69b9fd152a7a51647ae0e.png) Code snip it with output ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/8/3/8320831d828ae952a00de74ef63b1889ffe9a2f8.png) Thanks for help ---
