Goodies are free Add-Ons developed by Graphisoft to complete Archicad with specific abilities and features. As of Archicad 22, you can install all Goodies at once with the help of the Archicad Goodies Suite installer. Goodies are based on legacy code which Graphisoft does not support anymore. Feel free to use them but please be advised that they might not function properly and they will not be fixed or upgraded.
You can download the installer of the Goodies Suite from Graphisoft's download site. Please find more detailed information on each add-on of the Goodies Suite in the articles listed below.
