Use And Installation


Eyas can be downloaded from the Food4Rhino Website. We ask that you fill in a form that will allow us to notify you of updates. A self extracting installer is used to install Eyas to your work station. Eyas requires licensing, the user needs to install a license file. Eyas is currently free and the license allows you to use the current version for 12 months as evaluation while in Release Candidate/Beta version. The plug-in is fully operational in all three flavors of Standard, Professional and Enterprise. The user needs to email an auto created machine ID string. A license file will then be emailed to you from the form the user filled in on the Food4Rhino website prior to downloading the plug-in. Without a license file the plug in may be used for 30 days in trial.


If an Eyas component is not working it is likely because the current session of your grasshopper definition does not contain at least one instance of the EYAS license manager on the canvas. AT LEAST ONE INSTANCE OF THE LICENSE COMPONENT MUST BE INCLUDED ON THE CANVAS IN A USER DEFINITION. As an example, consider the ExcelGetValue component, in the first instance the component is not licensed and the bottom balloon says NO LICENSE, the second instance is a correctly licensed component and states one of the three flavors of STANDARD/PROFESSIONAL/ENTERPRISE.


While released as a Release Candidate/Beta version the EYAS  plug-in is fully operational in all three flavors of Standard, Professional and Enterprise. The user will be emailed a license key when registering for a download from the Food4Rhino Website.

First Time Installation

For the first time installation of EYAS, the user must drag and drop the LicenseManager component onto the canvas in their grasshopper definition, double click the LicenseManager component, the component will then prompt the user to install a license by copy and pasting the supplied license key in to the dialog box, see below


The user only needs to do this once. Once a license file has been installed, EYAS will work without the need to reinstall, provided the license manager is dragged at least once to the canvas. The license manager should now say licensed in the message balloon at the bottom of the manager.


The output of the component gives details about the currently installed license.

L- Licensed

LT – License Type
