To be able to xref drawing(s) on a mobile device (AutoCAD mobile App).
Essentially having a design drawing in the cloud (Box/OneDrive etc.), creating another drawing on site (coming directly from a measuring device - dxf) and then overlaying (xref) this drawing onto the design drawing for comparison.
It is possible in the AutoCAD web version, however it would be good to have this option for the mobile devices so there would be no need to carry a laptop around.
