Do scans work in a CAD program?
Scanners produce raster images, not the vectors used in CAD programs. When CAD software allows import of a raster, it will display it as a raster (i.e. dot based) image within the CAD document. The lines in a raster image in a CAD document cannot be manipulated in the CAD program. The CAD program will not convert it to vectors unless assisted by a conversion program like TracTrix.
