In an era where seemingly every document and detail is digi-tized and stored for posterity, many engineering plans and drawings are still printed out and maintained in printed form, with comments and changes written directly on the document. While most groups have CAD and similar software, there are still filing drawers full of paper plans and schematics that may be referred to more frequently than their electronic counterparts. There are good reasons for relying on printed documen-tation, even today. Documents can easily be shared in meet-ings. Engineers can make ad hoc changes, mark up designs and write comments. Digital files and storage can be more easily protected against someone who is a partner today, but may be a competitor on a different project tomorrow. Paper documents may also have to be delivered to the customer at different points in time in a project.
