FadeToGray cleans up all xref attachments, fixes block properties, and turns everything gray. So the drawing can be used as a background layout in another drawing.
- Load fadetogray.lsp file to AutoCAD.
- Run fadetogray command
- Lisp will clear all connections to external drawings, fix block colors and it will make everything gray.
- Now you can use the drawing as a layout for another drawing.
