This chapter discusses ways to import existing drawings into the AutoCAD® 2019 software through tracing, scaling, and scanning. At times, you'll want to turn an existing drawing into an AutoCAD drawing file. The original drawing may be hand drawn, or it might be a PDF from another source. You may be modifying a design that someone else created or converting your library of older, hand‐drafted drawings for AutoCAD use. Perhaps you want to convert a hand‐drawn sketch into a formal drawing. In addition to importing drawings, you'll learn how to incorporate drawings in Portable Document Format (PDF) into your AutoCAD work.
