AutoCAD has no out of the box Sketchup importer, however for several years there has been a free add in on the Autodesk App store that addresses this limitation.
Once installed, a new command IMPORTSKP is available, or alternatively an Import Sketchup button is present under the Add-ins tab. SketchUp Import 2016-2023 now supports SKP file format versions from 2014 to 2021. SKP import versions 2017 and later is only supported on 64-bit platforms. NB: The 2021 add-in is only supported for AutoCAD 2022 or later.
Once executed, and the SKP file selected, the Sketchup file comes in as a block. It will scale according to units settings defined within the original sketchup file and the INSUNITS setting of the current AutoCAD drawing.
Note the unitless setting of the imported component. If settings are set to unitless then the element will need to be scaled to suit.
The link to the add-in is on the App store and can be downloaded from here:
