I am starting to learn Sketchup. I only have the free web version. I created a simple project and downloaded the .skp file. I tried to open it in vCarve Pro v7.5 (Shopbot version) and it says failed to open. When I downloaded I specified 2017 Sketchup download. I am guessing that the two are not compatible and maybe I need a newer version of vCarve or a more robust version of Sketchup. Any thoughts on the best way forward?
