Cutting Up STL files

Is there a free program that can cut up larger STL files into clip art? Most programs will slice, but I want to cut away sections of an existing stl file. Basically to cut an entire scene into clipart.

Both SketchUp and Blender will import .stl files.

I’m only trying to cut up my Amazon stl files, not Vectric. Sketchup and Blender can import stl, but can the cut out vs slice?

You’ll have to work with mesh editing tools. They aren’t quads or nurbs surfaces.
