OK, then I think LibreOffice help or forum would be a better place for your question.
What LibreCAD can do is to provide a DXF drawing or you can export the drawing to different graphic format like PNG, JPEG or PDF.
So you have to ask, is LibreOffice capable to handle one of these file formats.
I'd expect yes, at least for the graphic formats, but don't nail me down on that
