Many DWGs and DXFs provided by surveyors contain 3D survey points nowadays. If this is the case for you, it might be worthwhile not to use LibreCAD as LibreCAD will only show the 2D data. An alternative is to use Blender's DXF importer. Once imported, you can use the BlenderGIS plugin to perform some geolocation, and generate TINs from the survey via its Delaunay Triangulation tool.

I'm surprised that @LordOfBikes mentions that LibreCAD has issues with real world coordinates. I would've expect LibreCAD to handle it. My current workflow is to use AutoCAD to offset the survey from real world coordinates to a known origin point (usually a corner of the surveyed property site boundary). I was hoping that LibreCAD could do this too but maybe I am wrong. @LordOfBikes, is there any way to offset DWGs/DXFs to solve this issue? Ideally it could be something headless or via a quick script with minimal dependencies, so that the same solution could be used for other apps too.
