This repo is intended to be a starting point for creating an ETABS plugin in C#. It includes a small amount of boiler plate so that the plugin can compile and load into ETABS.
A more thorough overview of the repo can be read at the following webiste: https://kinson.io/post/etabs-plugin-quickstart/
Note that this plugin was built using Version 17 of the ETABS oAPI. Starting in ETABS 2018, a new api has been released and will provide backward compatibility for future releases, so it is recommended to update this reference. This new API is contained in the library file ETABSv1.dll and should be imported instead of the older ETABSv17.dll.
