İmport .fbx

Sketch up .fbx import

There is none. You will have to use some other software to convert it into a format like Collada (.dae) that SketchUp can import. Autodesk used to have a free application for this. It can be downloaded from Fbx Converter Archives but the documentation says nothing about Windows 10 compatibility.

There are some 3rd party import extensions. But may not be free …

Thank you
