Hi, I’ve just made the script (and code inside the C# component) available for anyone if you go to this page: pavilion.nuluca.com/marching-cubes/1-preparing-script You do need to be a member to watch videos 4 through 8, though, in this series (and to access the code and GH scripts for those). Hopefully you can think about becoming a member, that helps a lot. Still, your interest and engagement is truly appreciated no matter what! Thanks so much!

@@nuLUCA_studio Fantastic !! many thanks.

Hi, thanks for the question. The problem could be that you’re missing System.Linq in your “using” statements. Make sure this: using System.Linq; is up with your other “using” statements (like “using Rhino” and “using Rhino.Geometry;” ... it can be anywhere up there with them on its own line). If that doesn’t solve it and/or if you’d like to see a working script (Rhino 7 or 8) head to the Pavilion website: pavilion.nuluca.com/ig1/7-csharp-quick-look-part-1 From there you can look at or copy the C# code from inside the scripting component or you can download the Grasshopper files. Best of luck! And of course get back to me if you’re still having a problem with it.

@@nuLUCA_studio thank you for replying, I did use the component you provided ))

Thanks again! You got this!

Hi, this could definitely be mixed with other plugins. For something agent based like Culebra or Quelea you could start off on a path like this to create an environment, curves/circles could help define paths for agents. There’s a start to finish stigmergy / slime mold tutorial mid production right now that probably won’t be out until December but I might be able to do a quicker Culebra (since there’s a more recent (2022) update for this plugin) in the meantime. I’ll definitely keep that in mind. Thanks for watching!

Thank you so much! And congrats for sticking with it through the whole series! It can be so challenging to stay in it with something as complicated as Grasshopper. But it’s such a valuable thing to get good at … you’ll learn more tricks, make more connections, make new discoveries, faster and faster as you go (with and well beyond Grasshopper). Well done, it’s no small feat!

@@nuLUCA_studio And thank you for this awesome tutorial! You explain stuff very well. I'm going to tackle that Marching Cubes and Periodic Minimal Surfaces Series next! Cheers~

Thank you soooo much!!!

Hi, I just made the GH file for this video available here: pavilion.nuluca.com/marching-cubes/2-collecting-transformations Scroll down under "Downloads" (it's called Marching Cubes Video_02.gh). Check yours against this file (sometimes the smallest thing can throw everything off, as you probably know, and sometimes it can drive me crazy trying to find it). It might be something with a grafted or flattened tree ... but hopefully checking with this file will help you debug. Let me know if you still can't find it and definitely let me know if you have any issues with the downloaded file. Thanks! Good luck!

Thank you so much for pointing that out! It definitely happens more often than it should that I’ll write a C# component that a vanilla component already does. “Mesh Explode” doesn’t come with Grasshopper but is in the very useful MeshEdit plugin. You mentioned “Deconstruct Mesh”, though, which you can use to graft the “F” (Faces) output to plug into the “Construct Mesh” component (along with the un-grafted vertices). And then a much shorter script to get rid of the unused vertices (MeshEdit also has a component for this): private void RunScript(Mesh mesh, ref object a) { mesh.Vertices.CullUnused(); a = mesh; } Maybe you know of an even quicker way. I’m just starting a series (first one should be out this Wednesday or Thursday) that looks very quickly at every vanilla GH component. Probably won’t ever get to all of them but I bet this kind mistake will happen much less often.

@nuLUCA_studio keep uploading your tutorials. Your channel looks very interesting. Good job! 👍🏻

Thank you! I’m so glad you’re enjoying it! That means a lot. The next parts are out now. They’re at pavilion.nuluca.com. If you sign up you get these and everything else. It’s this support that makes these videos possible. Membership’s usually $32/mo but right now it’s $10.56 (until May 20, 2024). I really appreciate your note, please keep the feedback coming, it really helps and thank you again!

Yep, I’m with you there. Thanks so much!

Thanks so much for pointing this out. I’ve also had an issue with the C# scripting component in Rhino 8. Rhino 8’s quite new and there might be some bugs. I’m not sure if this is one of the issues you’re having but one thing I needed to do was type “GrasshopperDeveloperSettings” into the Rhino command prompt and then uncheck “Memory Load *.GHA assemblies using COFF byte arrays”. See this discussion: discourse.mcneel.com/t/rhino-8-i-get-into-trouble-with-the-script-editor-for-c-in-grasshopper/169514 There are two more changes you will probably need to make with Rhino 8. 1. Add “using System.Linq;” with the other “using” statements at the top of your code. 2. Add .ToList() in the line: “parameters = in_params.ToList();” I’ve added a complete script here: pavilion.nuluca.com/ig1/8-csharp-quick-look-part-2 Under “Downloads” it’s called “Venus Flower Basket (video_08 for Rhino 8).gh” Hopefully this helps.

@@nuLUCA_studio Hi, thank you for your fast answer. I already had Memory Load unchecked by default. I downloaded your rhino 8 code, and it is not working either. With the code I wrote following your videos I got 3 errors. 1. Operator '<' cannot be applied to operands of type 'int' and 'object' [49:21] 2. Argument 3: cannot convert from 'object' to 'double' [51:61] 3. 'Script_Instance.UpdateParameters(List<double>, Curve, double)': not all code paths return a value [85:24] With your code I only get the first 2 errors. This is quite intimidating, because it is the first time I dare to write code. Thank you again.🤩

@@nuLUCA_studio Also, the code I wrote following you was working until the last "public" part.

Sorry! Your code is working just fine! Error from my part. I'm checking the differences between your code and mine. Thank you!!!

So happy to hear!

Thanks for watching and thanks for the suggestion. I'll work on putting something up like this.
