Sometimes you need to reference other drawings, and nanoCAD lets you insert those other drawings in the one you are working with. This is called 'DWG references' or 'external references' or 'xref' for short. In this video, you learn how to insert drawings in drawings: • Using the XAttach command to attach an external drawing to the current one • Editing the attached drawing and updating it • Toggling the visibility of xrefs • Removing xrefs form drawings by unloading them
