How can I go about using Dynamo to number my elements in sequence based on the curve used to generate the element? (See the below image for more clarification about the number sequence I’m trying to achieve.) [NumberLine] Not sure if that makes things easier, but each of these elements were plac…

If the lines and points were created in the correct order it would make things really easy. Where are you getting your geometry from? You can also check out this post for ideas. [image] Python script error on sorting points in a clockwise order Developers Hi all, I would…

Nick, I’m generating the Points along the curve based on certain rules for the spacing, then I’m projecting those points to a topography and placing my elements at those points. That’s been part of the problem that I have been running into, since the points are not technically on the curve after t…

How are the curves generated? If the curves are created in the correct order, the points should also be generated in the correct order. These nodes will take your original curves and reorder them (clockwise) so it should get you your curves in the correct order. [image]

Thank you for the script. My issue is not with the order of the points though, I can get them to number in the correct order. The part in which I’ve hit a wall is when it comes to trying to get the elements to know which curve it is closest too and number in sequence based on that curve. See the …

Can you run Geometry.DoesIntersect before you project your points? It seems like it would be best to get the points all figured out first. Then you can project the onto the topography and create elements after the fact. After that, it’s just setting the parameters for the new elements.

Yes, I could do that. But how do I go about breaking up the list of points by curve? That’s where I’m at now… I’ve got my points and the curve that they are on. But for the life of me I cannot figure out a way of telling Dynamo that I want to break up the list of points into sublists based on th…

Can you post an image of how you’re getting the points and the curves they’re on? That might help me figure out how to sort them.

Here’s one option that might work. [image]

By the look of your diagram, it appears that you need your spacing to be as equal as possible on each line. This means using a parameter to define the point locations isn’t viable as it fixes the count, not the distance. In addition, your lines may not always be in order and this should be a priori…

Thomas, I tried to recreate your script, but I keep getting the following error. Not sure what I’m doing wrong. Any ideas? [~2000]
