I cannot import CAD 2019 into Sketch up o
r Layout. My old 2008 can but not 2019
The 2019 version of AutoCAD came out AFTER SketchUp 2018, so SketchUp does not know how to read those newer files. Save the CAD file to an earlier version.
if you don’t have access to the full blown ACAD you may use the free ADesk DWG TrueView 2019 f. Windows to convert to the disred format version by yourself.
