If you came to one of my presentations at the 2018 SketchUp 3D Basecamp in Palm Springs and are interested in the slides, here they are. You can find all of the code examples from the talks here (and on your USB “Stick of Knowledge”).
In this presentation, I not only gave an introduction into Ruby coding with SketchUp, but I also explained how my own SketchUp extensions came to be and what is behind those from a coding perspective.
Feel free to write any questions you have into the comments below. All the best with your Ruby coding endeavors…
