All branches of engineering use drawings to design parts and facilities prior to fabrication and construction. Drafters and designers produce a range of sizes of engineering drawings. Although drawings typically are produced using computer-aided drafting software such as AutoCAD, they still need to be printed on large-size plotter paper for engineers and construction workers to use in the field. Size A1 drawings commonly are used for field work and are the easiest to fold. While it is recommended that you store larger drawings in a tube, there may be times when you need to fold a large-size drawing, such as a Size C drawing.
Fold the drawing in half along a vertical fold line. Bring the right-hand edge of the paper to the left-hand edge of the paper with right sides together.
Fold the left-hand edge of the top layer of paper back halfway, along a vertical fold line, so that the title block of the drawing is showing. The left-hand edge of the top layer of paper should now be aligned with the right-hand edge.
Lift the entire drawing from the table and turn it over.
Fold the right-hand edge of the top layer of paper back halfway, along a vertical fold line, so that the right-hand edge of the paper is now aligned with the left-hand edge.
Lift the entire drawing from the table and turn it over so the drawing title shows at the bottom.
Fold the drawing in half using a horizontal mountain fold so that the title block of the drawing remains at the bottom.
Tip
Consider rolling large drawings for storage in tubes.
Warning
Always fold maps with clean hands.
