The Roof Surfacer add-on allows users to apply 3D cladding to an existing roof.

Before Starting

1. Download and install the Goodies package here.

2. Add the Accessories Library to the project library. It is located under the ArchiCAD version folder under the Graphisoft folder in the Applications directory on Mac or the Program Files folder on PC.

Note: If you cannot locate the Accessories Library under the ArchiCAD version folder this means that the add-on has not been installed properly.

2. Right click, in the menu select Split into Single-plane Roofs.
