I am trying to export a Graphic3D object in a vectorial form in PDF. However, the previous methods suggested in here do not work for version 12.3 now. Both Export[NotebookDirectory[]<>"foo.pdf",Graphics[Inset[Graphics3D[Sphere[]]]]] and trying to print the graphics via Microsoft-Print-to PDF produces a fuzzy rasterized pdf file, which is undesired. So what is the correct way to export such graphics?
UPDATE
I supposed that something like Graphics3D[Raster3D[{{{1, 2, 3}, {4, 5, 6}}}/10]] should be more easily exported, but I still have no idea on how to operate on it.
