Increased take-up of internet technology and company intranets will stimulate growth in European sales of computer aided design and computer aided manufacturing (CAD/ CAM) software, according to a study by market analysts Frost and Sullivan. The research predicts that revenues in the European CAD/CAM industry will more than double from $2.3bn in 1997 to $5.2bn in 2004, with CAD accounting for 41.3% of the market. CAM and computer aided engineering (CAE) will make up 27.8% and 11.1% of the total market respectively. Suppliers have been quick to produce web- enabled CAD/CAM products for manufacturing and design companies that are keen to distribute their services over company-wide intranets. The integration of product data management (PDM) software with CAD/CAM software allows different departments to access data, speeding up the process of product development. Frost and Sullivan identify the greatest potential for future revenue growth in the PDM sector. PDM will account for 19.8 % of the European CAD/CAM market in 2004. It is now beginning to gain popularity with large multinational companies as a way to efficiently manage manufacturing in different geographic locations, says the study.
