If you aren't particularly experienced in using illustration applications, it can be difficult using a computer to get ideas on screen. For a designer, there's nothing quite like pen and paper for quickly developing ideas and sketches and computers can affect the spontaneity of exploring ideas. One option is to scan in your hand drawn images, but raster images can't be used with popular CAD programs.  

RasterVect 14.4 is a useful application that enables users to convert raster drawings into a more versatile vector format. You can scan hand drawn images, convert them as well as open and edit them in almost any CAD application. The program has four different conversion methods and includes a selection of viewing tools.
