Study on Constraint Information Visualization in CSCD

Constraint information is crucial content of CSCD. It becomes more complicated and various with the expanding application and hard to manage. In order to control collaborative design flow efficiently, detect constraint conflicts early and decrease contradiction extension speed, intuitive and vivid constraint information visualization method is created. This paper discusses detailed signification and formalized description of constraint information visualization in CSCD based on classification and representations, puts forward two key procedures in visualization: one is counterpart modes between constraint information and available visualization techniques. The other one is harmony system of assessment based on constraint harmony concept. Crucial steps of constraint information visualization in CSCD such as constraint information mapping, dynamic track have been pointed out as well. The application of constraint information in collaborative design will give an important direction to complicated system control and complicated constraints management
