I wiped and re-installed my Mac software, primarily on the basis that I wanted to run Sketchup with this plugin so I was gutted to find it does not work with Sketchup 2015 (I just found the comment hidden away that it does not work with 2015 64bit which I assume is the issue!).
How serious is the problem? Can you give an idea of how big a problem it is (just in case I can help to fix some problems myself) or a timescale if you are planning on fixing it yourself?
Ruby is not my main skill, but I would give it a go if you were to give me some direction as to the problems?
