From AAG to A CAD file

[Nadjei74]

So I know with a software like Analysis Situs, I can construct an AAG of a CAD file and dump it in a JSON file. I want to know if there is a way, we can extract the CAD file back from the AAG. I guess my question is, its there a way I can store a cad file in a neutral format that is not STEP or Brep and still be able to retrieve a CAD file from it?
