Every time I try to export a sketchup model to a 3d model it crashes. Also it does the same when I try a 2d graphic. I have the latest version of Sketchup pro 2021. Im currently running Mac High Sierra10.13.6 on my machine at home. Is this maybe the reason it isn’t working? I haven’t had the chance to try it on the newer iMac at work yet.
Perhaps. Support for High Sierra was dropped with SketchUp 2021.
