I can’t seem to find a compatible STL exporter for SU 2025. It’s located on my File menu in 2024. Am I missing something?
in file / export / 3d model (and pick stl) ? doesn’t it work for you ?
I 3d printed something earlier that I exported that way. Maybe you were using an export extension that is not compatible anymore ?
There’s been a native .stl exporter in SketchUp since 2018. No need to look for an exporter extension.
