Parametric Art/3D Extensions

I’m looking for some advice/guidance on any good extensions to us to help create 3D models that I would then slice (using slicer). I will then report the files to my CNC and cut the files to create parametric wall art/shelves/seats etc. I’m very new to SketchUp, but have been building my skills slowly and would like to create some cool stuff to output files to my CNC. Thanks in advance
