Your blog you are refering to is exactly the one I used as guideline for doing it. I’ve however only watched the latest post “Karamba to GSA and Robot”, unfortunately with no luck.
As far as I can tell, the new add-ons on your site for exporting to robot creates a new tab in grasshopper, and the newest add-on for karamba creates a new component called “ggKarambaExport” whereas the one I am looking for is a component called “ggKarambaRobot”
Sample for export.gh (12.3 KB)
The attached file is the way I would export a simple beam to Robot with the component I’ve got now.
Cheers
