algorithmic modeling for Rhino

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.

Location: Seattle, USA
Members: 608

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.

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.

Yes i look this post and other,

I have managed to repeat on a 2D grid.

But I have a problem doing it on extrusion. I don't understand why, maybe the problem i pathern string parameter.

Raja thank you very much for your help.

Ok have you got example for this with paneling tools?
Comment by Rajaa Issa on December 8, 2015 at 1:07pm

Your request is very common and logical, but often imposible in free-form surfaces (unless using special case surfaces such as extrusions).
I also understand that the manual work is long, but if you can do it on a small patch of your surface, then you can automate.

Comment by Rémy Maurcot on December 8, 2015 at 1:01pm
It's so long for manually test...

For a rationalize surface for me it's a surface or it is possible to map the same pattern of repetitive manner.

my request is far from trivial, during production it is important to minimized the number of panel !

Not sure I understand. What do you exactly mean when you say Rationalized Surface". A good test of whether your surface can be split into equal panels is to try to do a portion of it manually. If you succeed, then you'll likely find a way to automate it inside a tool.

Comment by Rémy Maurcot on December 8, 2015 at 12:32pm
I understand why, but is there any tools to make a rationalize surface ?
Comment by Rajaa Issa on December 8, 2015 at 12:17pm

Remy, it depends on the surface. Free forms do not typically lend themselves to equal panels.
