Not only the concept sketch design can be quickly defined in 3D and tested taking into account the climate conditions, it can easily refined to take a preliminary design of the façade into account. For this we can use the Paneling tool for Rhino and Grasshopper ( https://www.food4rhino.com/app/panelingtools-rhino-and-grasshopper )

This app allows a quick way of panelizing surfaces with 2D and 3D panels. Because of the ease of panelizing the surfaces, variants can be quickly investigated, simulated, tested and applied to the whole design.

#### Setting up the size of the panels

The proces makes use of a grid defined by the user or based on the UV coordinate system of the surface. Between the grid point the panel will be placed. If the grid is distorted, for example if the grid is based on the UV coordinates of a curved surface, the panels will be distorted and follow the surface. In this short introduction a basic setup is made based on the previous discussed design.

There are few simple steps to panelize a surface:

Lets get started:

• Draw a rectangle. This rectangle will be the basis for the panel.
• The panel can be defined by 2D or 3D objects.

• Define a grid on the surface.
• Select the surface to be panelized.
• Go to Paneling Tools > Create Paneling Grid > Surface Domein Number. This option makes use of te UV coordinate system of the surface.

• Define a grid on the surface.
• Define the grid size in the command line, by changing the amount in the U or V direction the amount of grid points will change.

• Define a grid on the surface.
• For a 3D panel we need a height reference, so we offset the grid: Paneling Tools > Grid Utility > Offset Points. Check the command line for the settings.

• With the grid correctly defined we have to select the panel which we are going to use. For this example we will use the 3D custom panel.
• Go to: Paneling Tools > Paneling from Grid > Panel Custom 3D and select the panel you made. Check the command line for the correct steps.
