The aim of this project is to support collaboration between textile designers and textile technologists, by identifying communication problems between them, and to use a suitable textile CAD system to help solve these. As a result, both textile designers and textile technologists should be able to make use of CAD systems in an appropriate way to tackle systematic problems of the design process by giving different contributors access to information and expertise of their colleagues. The support CAD system allows designers to develop comprehensive and compatible specifications which are consistent with their design ideas. The communication problems could be resolved by reliable specifications of the support system, such as database of information on fibre and fabric properties, as well as any available expertise and historical data. This can have wider consequences for the design process, as designers and technicians respect each others expertise, they might also respect each other's opinion in other issues and treat each other with higher regard.
