WeaverBird 0.5.16 NewYear
WeaverBird is the plug-in for topological transformations in Rhino and Grasshopper. It now supports colors and texture coordinates. It helps inventing, smoothing, modifying, thickening and preparing meshes for rapid manufacturing technologies. WeaverBird 0.5.16 NewYear. For Rhino 4.0 and Grasshopper 0.8. Now in “Wb” toolbar. Please upgrade to this version if you are using any earlier [...]Grasshopper tools in C#
Grasshopper features an impressive amount of highly interlinked components – from lines to trees, from circles to graph editors. Sometimes, however, when design tasks become more advanced, we might need to further customize this plugin by directly borrowing from Rhino commands. With these scripting components, the user can quickly solve otherwise more complex design behaviors. [...]Knitting patterns on a surface in Grasshopper
Last week I have been visiting my brother in Barcelona. Maybe I should blame the maritime environment if I started experimenting with knots and threads. So, what I am going to show you today is a method to digitally knit yarn in Grasshopper. A similar definition to make a chaining fabric is provided at the end [...]Giulio Piacentino's Groups

Building a component with Visual C# Express 2008
While building a component with Visual C# Express 2008, the largest difficulty to overcome is arguably the setup because of the time to get accustomed to the interface and the environment.
In less than 10 minutes, this video shows how to set up Visual C# Express 2008 to produce a simple component with icon for…

Giulio Piacentino replied to Andy Payne's discussion 'Weaverbird in 0.8.0063'
The 'Rhino version not specified' is probably a different problem. I'd need a screenshot of the error. Does anything else appear?
Giulio Piacentino replied to Dimitry A. Demin's discussion 'VertexColors'
You can also set the Count of VertexColors (mesh.VertexColors.Count = 100) and then set each member.

Giulio Piacentino replied to Panos's discussion 'Runtime error (ArgumentTypeException): expected IEnumerable[Point3d], got list'
Hi Panos,
there were two problems in the code - I hope I fixed them.
Rebuild was a list of floating point numbers, not a single integer.
Use rhinosciptsyntax marshalling if you use rs.DeleteObject(id). Otherwise, the input will be pure RhinoCommon…
Giulio Piacentino replied to Julz's discussion 'a simple question...'
Hi Julz,
I cannot answer the question above directely because it is nested too deeply. Also, I am not so sure what the v normal of the ControlPoint is.
Can you start a new thread with that question? Maybe with a small diagram: that would really…
Giulio Piacentino replied to Panos's discussion 'Runtime error (ArgumentTypeException): expected IEnumerable[Point3d], got list'
Hi Panos,
I think it might have to do with the content of the list, but could you please post a Grasshopper file with a sample?
Thanks,

Giulio Piacentino commented on Sama's blog post 'GH SDK'
Hi Sama,
I made a video and published this post a little time ago. It goes through all steps to make the .gha file. It should not be very different in VS 2010.

Giulio Piacentino replied to Yasushi Sakai's discussion 'DataTree,List,Item access from grasshopper-python'
DataTree isn't a very simple construct by its very nature... it's easiest when it can be avoided entirely, really.
Yet, maybe I can come up with a simpler example if it could use Add() and not AddRange(). Would that be appropriate in your…
Giulio Piacentino replied to Andy Payne's discussion 'Weaverbird in 0.8.0063'
Are you using the version above (0.5.16)? Every component should mention it.
Giulio Piacentino replied to Julz's discussion 'a simple question...'
This is tricky, but there is no bug here at first sight. The tricky part is that Point3d is a value type. See Value Types and Reference Types on Msdn for more information.
On line 116 you are modifying (with the Transform method) a copy of the…
Giulio Piacentino replied to Piotr's discussion 'piece of cake'
An advantage of the format function is that you could also discard unnecessary digits (say, 3.01 formatted to 1 decimal becomes 3 because the first decimal, .0, is irrelevant in this case) and add units.
In this case, it would look…
Giulio Piacentino replied to Piotr's discussion 'piece of cake'
Hi Piotr,
in fact the Round component would be enough. You could multiply by 10, use Round, then divide by 10. This would effectively give first-decimal rounding.
But in this world the "magic formula" exists as well. It looks like…

NurbsSurface ns = Srf.ToNurbsSurface();

A = ns;
Cheers,
- Giulio________________giulio@mcneel.com
Giulio Piacentino replied to Julz's discussion 'a simple question...'
Hi Julz,
because ToNurbsSurface() returns a new surface, you should store that in a new variable and work from there. With this single statement, the new surface, that you might achieve to modify, is anyways lost.
Cheers,

Giulio Piacentino replied to Dimitry A. Demin's discussion 'import utility'
Btw, there is an item in the issues about this. There is a good chance that we will decide to add the local path to the sys.path list automatically. This, however, might have some implications.
Thanks,
- Giulio________________giulio@mcneel.com
Giulio Piacentino replied to Dimitry A. Demin's discussion 'import utility'
Hi Dimitry,
utility is not a standard library module, right?
GhPython uses the same resolution as _EditPythonScript and Rhino. It instructs the runtime to look at the very same places. You can see them inside Tools, then Options (see image on the…

Hi Mark,
for a simple implementation of FilePath as David mentions, see this example.It would be, in short:

Giulio Piacentino replied to Grasshope's discussion '[help] script in GhPython node doesn't work'
Yes -- it is slightly different (mostly on the user interface and selection part). The rhinoscriptsyntax geometry methods are working in the same way. - Giulio

I thought it was developed with WB's catmull-clark subd. but for me that result is uncontrollable, but I like the result anyway¡¡
Thank you again, you rule¡¡

Hi giulio, great fan of yours¡
If you don't mind, i've got a question:
How do you control the mesh in your model (in your own web, see below) so it is arranged where it's possible? I mean, It is a regular mesh('ordenada' in spanish) in the main building and become irregular in the union...
Maybe this place is not the right place to ask you directly, please forgive me if not...
this is what I get:
thank's so much

- Hi, Guilo, wanted to say thanks for the great components!
Also, I had a question about your Bake Attributes component. I want it to bake my object name in this format: obj(123) and it currently looks like this: obj123
Is there a way to add the () before and after the number?
Thanks,
Zach
