Hello Will, for 3D visualization convert the above file to stp file. You can use Grabcad Workbench to convert it. Later from which 2D can be generated.
I think you need all the part files to view assembly files. So download part files also.
Hi Will,
If your AutoCAD version newer than 2018, use "import" command and select the "*.sldasm" file.
else save as your assembly file ACIS (SAT) format via Solidworks, then use "ACISIN" command.
