PanelingTools GH Add-On


PanelingTools GH Add-On

Parametric tools to create and manipulate rectangular grids, attractors and support creative morphing of parametric patterns.

This is a BETA version and works only with the latest Rhino 5.0 BETA on Windows 32 & 64 Bit.

Downloads and Installation (Last update: October 15, 2012):

Each time you update, please do the following:

1- Download the latest service release of Rhinoceros 5 and the latest Grasshopper.

2- Download the latest PanelingTools for Rhino 5.0 and Grasshopper. Make sure to double click on the installer to install.
3- Open Rhino, you should see PanelingTools menu in Rhino. Open Grasshopper, you should see the PanelingTools tab in Grasshopper. 

Where to start:


The PanelingTools for Grasshopper Primer (PDF) has many tutorials and detailed description of all components with examples. You can use as a start point to learn about the plugin.

Download The Primer Examples and Tutorials. This includes all components example and tutorials as Grasshopper definitions.

First step is to create a rectangular grid using one of the tools in "Grid" tab.  Some of these components take a list of points, which you can generate using GH standard components, or divide a curve using one of the tools under "Curve" tab of PanelingTools.

Once a grid is created, you can shuffle it using one of the attraction methods under "Grid Attractors" tab.  One output is the shuffled grid, another output is the normalized weights based on the attraction method that can be used for variable offset or variable paneling for example.

"Grid Utility" tab helps you do things like extracting points from the grid, replace points, extract center grid, expand grids, create surface from grid, etc.

"Panel Utility" tab has components to pull panel edges to a surface using pull, iso curves or shortest path.

"Panel2D" tab has many ways to panel the rectangular grid and populate 2D components.

"Panel3D" contain components to populate 3D patterns between 2 bounding grids.

If you used PanelingTools plugin for Rhino, then the Parameters tab is for you.  You can use PanelingTools for Rhino to create your grid, then input into GH as a tree structure using "Select" component.  The "Bake" components is to bake a grid in a format that can be used by PanelingTools plugin for Rhino. If you only work with GH, then you can safely ignore this tab.

Note: All input/output of PanelingTools Add-on to GH use standard geometry and you can use standard GH components to manipulate them. Grids for example are nothing but simple tree structures (no nesting). You can think of it as a list of rows or paths that contain certain number of leafs or elements.
It is important to try to avoid FLATTENING a grid. If you have to flatten a grid, there is a utility to recompose it if you knew the number of rows, but seriously, stay away from flattening!

Please feel free to post bugs, questions and suggestions to improve the tools. Please use the discussion of this group to post question when possible.

Hi Tal, Please start a new "discussion" to be able to attache files, etc. Comments are not meant to be responded to.
But to you question, in general, you should be able to add attraction using PT for GH. Please start the discussion, and we can take it from there.

Comment by Tal Fainzilber on December 12, 2016 at 3:02pm
Im new in Gh and i just try for the first time the panelling tools..
I want to make a grid with no equal frames
And after to use the points and the segments with attractors.. someone told me that if it not equal i cant make it
Is it true? And if it is there is something else that could help me?
P.s-how i put here print sreen if i want to show it well?

Thanx for your help, Rajaa.

Spiral, can you please start a new discussion thread ("Add a discussion" link above), and share a sketch of what you need?

Comment by spiral on November 3, 2016 at 10:00am

all super runs, except Chebyshev grid equal to the diagonal?

Comment by Rajaa Issa on November 3, 2016 at 9:48am

Maxim, are you able to see PanelingTools menu in Rhino and run PT commands (for example ptGridArray)?

Comment by Maxim Alexandrov on November 3, 2016 at 9:35am

Hi all!

I have a problem, after installing PT grasshopper plug-in is not loaded, the program displays the following message:

"An error occured during GHA assembly loading:
   Path: C: \ Program Files \ Rhinoceros 5 (64-bit) \ Plug-ins \ PanelingTools \ Win64 \ PTComponentLibrary.gha
   Exception System.IO.FileLoadException:
   Message: Could not load file or assembly "file: /// C: \ Program Files \ Rhinoceros 5 (64-bit) \ Plug-ins \ PanelingTools \ Win64 \ PTComponentLibrary.gha" or one of its dependencies. Operation not supported. (Exception from HRESULT: 0x80131515)

Exception System.NotSupportedException:
   Message: An attempt was made to load an assembly from a network share that in previous versions of .NET Framework could lead to putting the assembly in the "sandbox". This release does not include the .NET Framework default CAS policy, so this download can be dangerous. If the load is not designed for the isolation of the assembly, turn loadFromRemoteSources switch. For more information see. On page

Please help to solve this problem.

ASAP, Thanks Rajaa.

Good evening !

Comment by Rajaa Issa on December 8, 2015 at 1:45pm

Start a discussion topic and attach your surface and attempt. We can discuss it much better there, than in the comment wall.
