4. Once your project is created, add a reference to the CSI API library. This will be located in the installed ETABS directory, typically C:\Program Files\Computers and Structures\ETABS 22\ . If you are making a plugin only for ETABS, select the ETABSv1.DLL . If you'd like your plugin to be compatible with other CSi products, such as SAFE or SAP2000, use the cross-product API library, CSiAPIv1.DLL .
