With the rapid development of China's space industry, digitization and intelligent is the tendency of the future. The applications of the waveguide are gradually widespread. During the thermal test phase, the routes of the test waveguides are similar for each spacecraft. Although the waveguides are highly standardized, so far it needs engineers to design the particular route of the test waveguidess, then map the engineering drawing for every test. In order to efficiently design the route of waveguide, it needs to design an application to help the engineers. With the help of the MFC(Microsoft Foundation Classes) and the pro/toolkit, it is easily to do the modeling and simulation. After automatic design the particular the route of the waveguide, the API of AutoCAD type library is used to help to modify the engineer drawing. Engineers can supervise every step of this application, and easily to modify the key parameters.

With the growth of information technologies in the field of computer-aided design, the concept of CAD acquires new meaning and changes the contents. More and more a new definitions, i.e. Building Information Modeling - BIM, Fabrication Information Modeling - FIM, Integrated Structural Modeling - ISM, Building Lifecycle Management - PLM and others are encountered, the concept of which may be described as way to develop the strategy of building project design, construction, and maintenance management based on the computer aided modeling and simulation technologies. Examine BIM application in building design process it can be assumed that of object modeling and simulation technique comprises a full range of actions starting from the development of virtual model of the project under consideration, describing all physical parameters characteristic of a real structure, defining the conditions of its position. Then analysis of model behavior under real maintenance conditions is performed: effects of different character are described and the results obtained are analyzed. The results received by next step are presented in common technical documentation form: general arrangement and erection drawings are generated, final detailing of connections and structural elements in the form of shop drawing or NC code is performed, bill of materials, cut lists, various reports, specifications and estimates are composed. During the last five years there is strong request from the market for the state-of-the-art computer-aided design applications developed to meet the needs and requirements of the Architectural, Engineering, and Construction as well as Plant, Process, and Power industries, for high performance, flexible and versatile tools with extended graphics integration to simulation and analysis systems within a user-friendly design environment that allows the close emulation of natural design phases and workflow to which structural are accustomed. This could became possible due to the innovative development of ‘new generation’ structural software application capable to maintain an intelligent and true 3D real-world simulated structure containing all the information required for the general and detailed design, fabrication and construction of engineering structures, enabling designers to operate intuitively in the adaptive high-performance real-time visual modeling environment while simultaneously achieving high-quality results by applying powerful simulation, analysis and optimization methods which would guarantee a rational and effective choice of the constructive decision. It has to be flexible to enable external best of breed vertical market products to be linked to the application and hence creating an open design environment; this enables members of a workgroup to collaborate effectively, performing the multiple tasks associated with construction design.

This paper presents the design and analysis of new proposed topology micro-electro-mechanical system (MEMS) inductor. This new symmetric MEMS inductor is designed to reduce the total length of the conductor strip and hence reduce the resistance of the metal tracks. This results significant increases in the quality (Q) factor of the inductor. In this paper, the MEMS inductor is designed using CoventorWare®, which is powerful software for MEMS computer aided design (CAD), modeling and simulation. Results indicate that new symmetric inductor topology has thehighest Q-factor and it hasbeenimproved bytwo times compared to circular inductor. The analysis revealed that area of the symmetric inductor has reduced by37.5% compared to the circular inductor. Result has proved that the reduction of length of the conductor strip has reduced the resistance of the metal tracks and results in a high Q-factor inductor.

Successful and efficient exchange of product model data has been a major challenge in the shipbuilding industry for the past two decades. The Standard for the Exchange of Product Model Data (STEP) has been developed to enable this capability. Four STEP application protocols (APs) to facilitate the exchange of structural and distributed systems models in shipbuilding were completed in 2003 and were adopted by the International Organization for Standardization (ISO) by mid-2004. In August 2003, ISO 10303–216: Ship Moulded Forms (AP216) became the first shipbuilding STEP AP to be published as an international standard. Participants involved in these efforts represent several major US shipyards, the Navy, and their computer-aided design/ engineering (CAD/CAE) vendors. The thrust of shipbuilding data exchange efforts has now shifted from development to implementation. This paper will report on efforts to develop and use translators for this AP to exchange hull form product data in the ship modeling and simulation arena. In addition, process simulation is becoming common in the design of new ships to validate that the design meets the customer's specifications. Current technology requires that the ship be modeled both in the computer-aided design (CAD) environment and then repeated in the simulation workbench. Not only is this effort inefficient, but it is inherently error prone. Through the National Shipbuilding Research Program (NSRP)-sponsored Integrated Shipbuilding Environment (ISE) projects, we have developed tool sets that use AP227: Plant Spatial Configuration to permit the design to flow smoothly from the CAD workbench to the simulation workbench. This paper summarizes the efforts to develop and use a suite of tools that enables US shipyards to become more productive. It details the specific successes in using AP216 and AP227 for modeling and simulation, as well as efforts to exchange design data electronically between CAD systems. The report also outlines efforts that are underway to use other APs to successfully exchange data describing ship electrical; heating, ventilation, and air-conditioning (HVAC); and controls systems.
