Abstract:

It is possible to produce a computer-generated isometric illustration of sufficient quality for most applications directly from a scanned engineering drawing. The process described in this article uses Corel Trace and Corel Draw, but it can be adapted to suit other drawing or CAD programs, and it can generate sophisticated isometric illustrations.
