Hi all,
I recently made a plugin for Grasshopper versioning called GHShot (short for Grasshopper Snapshot) - https://www.food4rhino.com/app/ghshot. It is part of my PhD research project and is free to use. It would be great if you could give it a try and feedback is always appreciated 
The idea is that you will be able to send your parametric models progression (versions) online at http://ghshot.metadesignlab.com seamlessly as you develop them. Once it is online, you can :
- track your overall design progression
- download previous versions
- compare and see changes between versions
- merge versions (experimental)
- share it with others to collaborate (others can rate & comment too)
More information is available at the website above and I’m also happy to answer your questions here. Short video: https://www.youtube.com/watch?v=d2ULwW03G5k. Hope you will find the plugin useful.
Thank you and warm regards,
Verina
