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.

Deviation of a diamond grid from double curved surface 1 Reply

Hi,I've created a grid with domain length from a double curved surface. The idea is to apply diamond flat panels. Due to the double curved surface the grid gets "adjusted" to fit the curvature. Is it…Continue

Check this discussion about how to populate a hex pattern on a rectangular grid.

If you need further help, please post a sample.

Hi Rajaa,

Does PT GH support hexagon grids. I'm attempting to form a hex grid on a sphere but am having issues with the seam of the sphere and was hoping PT would help but can't seem to find any signs of hexagon grids as of yet.  Thanks for any help

that was helpful , thank you Rajaa !

Hi Mark,

There is no trimming support yet in the PT-GH, but there is one for the PT-Rhino. I will add to the list the ability to support trimming in PT-GH.

In the attached, I baked the component and the grid, then used ptPanelGridCustom with base surface, and PullCurves=Yes.  I hope that helps for now.

Hello Raja

is there any way to fit the pattern to the surface edges ...the surface i am trying to pannel is irregular so i used trim grid component , but the results are not satisfying , thanks for your help

Hi Rajaa,

Thanks for the quick response. Well - I noticed that ptVersion component is also missing. I think I know why this happened - I had copied an old 'gha' file into my new system and hence everything got jumbled up.

Now I deleted all the existing PT data in AppData folders and it works perfectly fine after the new installation.

Thank you very much for the help.


Just wondering - is there an easy way of UNINTALLING PT, as opposed to finding the plug in files and deleting them? It might be a good idea to include an uninstaller with the setup as the plugin doesnt appear in the Conrol Panel programs. (This was my observaion -it may be specific to my PC though).

Comment by Rajaa Issa on November 1, 2013 at 9:24am

Hi Sushant,

Can you please check and post the GH version and PT version?

To check the PT version, drag the ptVersion component (under PanelingTools->Param menu). It should be 2013.5.8.0. Also make sure you have 0.9.0061 GH version (GH->Help->About).

Let me know how it goes.

I am getting this weird error with 2 missing components! I have tried to download the latest version and re-installing but it still comes up as i open my old definition. Any fix for this? See Image.

Many Thanks
