How do I download and assembly this model from GrabCAD? (noob)

I saw this model on Grabcad that I want to download and use in 3D software.
The pictures show a complete car, but then the files are all separate into parts. I tried opening the .stl files with Rhino but without success, not sure if there are missing files (author posted that he added any missing file). Am I missing something? Do I need to assembly it or open with Solidworks? Do .SLDASM and .SLDPRT files contain any 3D data?
Basically I want to convert to .obj for ease of use.
Thanks!

The original author saved the project correctly, they included all the necessary files for someone using Solidworks. They just didn't include the optional STEP files. If you can't get the STEP files from the author then maybe somebody with Solidworks can convert it for you.
STL files were originally intended to be used for 3D printing only. They still should not be used otherwise. STLs should not be put together in an "assembly". That's just the wrong methodology even if you find a way to make it work. Furthermore, STLs were never intended for editing. They were intended to be the final finished output ready for 3D printing. Even though it has become possible (even popular) to import STLs and make edits, it is still the wrong method unless you have no alternative.
Get the STEP files and go from there.

To download and assemble a model from GrabCAD, follow these steps:
Sign Up/Log In: Create an account or log in to GrabCAD.
Search for Model: Use the search bar to find the desired model.
Download Files: Click on the model and select the "Download" button. This will download a ZIP file containing all necessary files.
Extract Files: Unzip the downloaded file using tools like WinRAR or 7-Zip.
Open CAD Software: Open your preferred CAD software (e.g., SolidWorks, AutoCAD).
Import and Assemble: Import the files into your software. Follow the assembly instructions provided or place and constrain the parts manually to build the model.
This process allows you to work with and modify the model as needed. https://www.homegaragesolutions.com/
