摘要
This Paper describes a flexible framework for the construction of Human Computer interface (HCI) in CAD system. This framework is based on an event-driven and object-oriented model, which takes the interactive components as objects and converts user events into object messages, Considering the characteristics of CAD applications, we design an interface object model, a process control model and a communication model between user applications Therefore, this framework reduces the difficulty of application development and enhances the runtime efficiency.
