I don’t use SketchUp myself (mostly openSCAD, etc.), but I have some students who’ve been using it since @Tinkercad went away and I’d like to print some of their models, but I’m not having much luck getting usable STL’s out of it.
I’m using this plug-in: https://github.com/SketchUp/sketchup-stl
When I select the object and choose File -> Export STL, I get a file, but there’s nothing in it. Additionally, I get a dialog during the export process that isn’t very encouraging (106 faces exported 0 lines exported 212 objects ignored).
Any tips on turning .skp files into .stl files for printing?
