Graphics in office suites like MS Office or LibreOffice can be a mix of raster and vector graphics.
If you are interested in a raster image like a scanned plan or a visualization of a building, you can right-click and export it to an image file like jpeg, png or bmp which you can import into SketchUp “as image” (in contrast to “as texture”).
If the office document contains a vector drawing you might be able to save it as a vector file, convert that and import it into SketchUp. For example export as wmf, convert in Inkscap to dxf, then import dxf into SketchUp. Or if your SketchUp version supports pdf, export to pdf and import pdf into SketchUp.
