Removal of Points with Identical X Coordinates

[mathi]

Greating to the community!

I’m trying to filter out points that have the same X coordinate. I’ve been searching online but haven’t found a solution yet. Do you have any suggestions or tips to solve this issue? Your help would be greatly appreciated.

Thank you so much for your help!

I’m trying to filter out points that have the same X coordinate

Same X as what? Anyways this is what I thought of when you said that. This should do exactly what you are looking for with some editing.

Sort Random Points in Same Plane Highest Y

Okay, so I Need to cull all but 1 Highest (Or Lowest) Y point in the same X Length. Below, Rough terrible markup but I need the points not X ed out. [InkedViewCapture20230704_142758] Points Sort Y.gh (5.3 KB) I checked out one that @Joseph_Oster demonstrated. But his mind is way above mine and I could not understand how to convert his gh to what I need to do. I also looked at a few other topics but to no avail. The best I was able to come up with was culling all the points which defeats …

That’s elementary via code (2 lines in fact). Notify if you need a C# that does it.

Sorted into a branch per x value:

Hello, thank you for your response. I’m eager to learn more about C#. Although I find it very interesting, I’m still at the beginning stages of my learning journey. I would appreciate any guidance or assistance you can provide.

Hello Bernd Möller, thank you for providing such an incredible example. I am trying it out right now.

@mathi

any guidance

Well …

1. Forget Internet.
2. Turn off computer.
3. Get books, read’m many times.
4. If you know what not to do you are ready (and by that time you’ll realise that there’s no reason to turn on the computer (*)).

Anyway: get a simple take on pts coords (the first C# does the demo the second cuts the mustard via a GroupBy single line [ then - obviously - there’s the options around]).

LINQ_GroupBy_PtsCoords_V1.gh (116.7 KB)

Get this as well: an entry level take on LINQ matters (critical for any data mining - you’ll see what I mean some years later).

LINQ_GroupBy_Then_OrderBy_V1.gh (116.4 KB)

(*) That said I hate computers.

Here’s a quick three liner Python script that might help:

Side note: It’s always easier to help if one provides an example/case to work with

[Joseph_Oster]

You can group points that have the same X values like this:

duplicateX_2024Jan20a.gh (18.3 KB)
P.S. This is an example where results are more clear when you jitter the branch colors.

Rounding of X coordinates to 3 or 4 decimal places may be required.

Or cull groups that have only one point (ignoring points with identical X values) like this:

duplicateX_2024Jan20b.gh (18.4 KB)
