AutoCAD, a computer-aided design program from AutoDesk, allows you to create precisely-scaled technical drawings on your computer. For small businesses in fields like architecture and engineering, these portable digital files allow for easy sending to clients and collaborators, prompting many to import their old paper designs into the program for conversion into digital formats. Although a number of paid applications exist to simplify the process of converting a scanned paper design -- if you need the AutoCAD file to exactly represent you paper version -- your best bet is still importing the file and tracing over it. While tedious, this process guarantees accurate and complete conversion.
