Does anyone know if you can create a non-earth local grid in QGIS. Local grids were commonly created in the past and are plane grids with eastings and northings from a specific reference point. QGIS only appear to be able to use real world coordinates with known projections. MapInfo has a non-earth feature that allows you to import local grid data and display it without it being in a known projection. This is particularly important when entering old data which was not referenced to real world coordinates.
