Because you already have the vectorial PDF file, you can import it as a DXF file, via Inkscape (Inkscape is a professional vector graphics editor for Windows, Mac OS X and Linux. It’s free and open source)
(for the clip I used another program running only under windows and export as SKP)
// edit:
For those who don’t know or have not made connections, the basic idea is that you can import in SketchUp a PDF via/if you use a 2D graphics program that opens PDF files and exports data to DXF files.
I gave the Inkscape example, because it is free and works into several operating systems, but Adobe Illustrator, Corel Draw, Affinity Designer, etc… can also be used.
