Close framework structure becomes recently a competitive solution for taxiway bridges. Due to no pile foundation construction, it has short duration and significant economic benefits. The development of close framework CAD system adopts Visual Basic and bases on secondary development interface in AutoCAD VBA to draw construction plans, such as structure diagram, bridge layout, prestressed tendons and ordinary reinforced chart. Another feature is the automatic generation of materials amount Excel tables and model for finite element analysis. The main program code of graphic object realization and deign parameters import are described. For the unique professional characteristic in airport project, the software system has a considerable engineering prospect.

Aimed at disadvantages of tedious work of the Gear Transmission design, Visual Fortran is taken as the development platform, and design data are stored and managed by self-developed program and database technology. A CAD System for Gear Transmission named GTCS is researched and developed. The system integrates designing and drawing in a body, and fully uses the powerful numerical calculation function of Visual Fortran and the function of Windows interface design, as well as the secondary development function of AutoCAD and database technology, etc. The software can realize designing and calculating of involute gear transmission mechanism, automatic drawing and various kinds of results post-processing. Results show that the research results greatly improved the efficiency and quality of the design. The result documents are easily accessible by other structural analysis software (such as SolidWorks, ANSYS, ADINA, etc) and similar design software, and convenient to use for the follow-up work.

The traditional methods of physique monitoring are limited to medical and hygienic science, which can not meet the requirements of development in modern society. We apply in this paper the method of RBF Neural Networks to the CAD system development of physique monitoring, and achieve a consulting result approximating to the domain expert knowledge with better performance.

Abstract CAD modelling can be referred to as the process of generating an integrated multiple view model as a representation of multiple views of engineering design. In many situations, a change in the model of one view may conflict with the models of other views. In such situations, the model of some views needs to be adapted in order to make all models consistent. Thus, CAD models should be capable of adapting themselves to new situations. Recently, agent based technologies have been considered in order to increase both knowledge level and intelligence of real and virtual objects. The contribution of this paper consists in introducing the intelligent agents in intelligent CAD modelling. The proposed agents are elementary geometrical and topological objects. They incorporate the functions of observation, decision and action, and possess their own knowledge. Agents have the capacity of communication and inference based on the feature grammars. They are modelled as bio-dynamic objects that enjoy the properties of fusion, division and multiplication. Being aware of the context, the proposed agents interact to form potential regional transitory communities, called regions. Being aware of their belonging in a region, agents interact by generating virtual links (virtual extensions). These virtual links produce: (a) fusion of agents, (b) division of agents and c) multiplication of agents. The emerged agents interact with the other agents in a region to recognize each other and to form specific sub-communities, called intelligent features. From a CAD software development point of view, this paper advocates the idea of a new phase of CAD system development based on the agent-oriented programming (AOP) paradigm. Highlights This paper proposes the agent paradigm for intelligent CAD modelling. Second section presents the state of art. In the third section, using the linguistic hypothesis of product design, a feature modelling formalism is presented. Fourth section presents a formal model for agent modelling. In the fifth section, agents for feature generation and modelling are formalised and modelled. The sixth section presents the application of the method. Finally, in the last section, the conclusion and future developments are proposed.
