Delcam enjoyed a global 12 percent sales increase in its sales of CAD/CAM systems in 2004, but it was knocked down hard by the weak dollar. As 60 percent of the English company's sales are in the dollar area, the bottom line was badly affected. Delcam showed the first complete CAD/CAM system for the design and manufacture of footwear at several shows in the past few months, including the ANPIC fair in Leon, mexico, the APLF in Hong Kong and SIMAC in Bologna. Company officials have noticed that Chinese companies have started to develop their own systems, some of which incorporate some illegal copies of Delcam techniques, but found that they are not technically efficient.
