Based on the basic process of mechanical product design and a modular design idea, the module includes three parts, i.e. design calculation, computer-aided drawing and foundation database. The design calculation mainly includes the commonly used design calculation program in mechanical product design, and the computer-aided drawing mainly includes the parametric drawing programs about the drawing environment and the commonly used machine parts, the foundation database mainly stores the data related to the mechanical product design. Then a computer-aided design module for mechanical product will be constructed by Autolisp and DCL. And the proposed computer-aided design module is developed on the friendly interface, easy to use, and can provide mechanical engineers for product design efficiency greatly.
The three-dimensional (3D) modeling environment of AutoCAD is used to represent and solve problems of structural geology. As an alternative to bi-dimensional (2D) techniques of classical structural analysis, the 3D capabilities of the software are used for modeling, positioning and measuring geological structures. To introduce the proposed method, two practical examples are presented as exercises with detailed instructions. The technique consists in precisely representing the geometrical entities that comprise the geological problem within three-dimensional space to enable the direct measurement of structural parameters. Accurate results, such as fault displacement and the attitude of several structures, are obtained with the dimension tools of the program, so no calculations are required. Diverse 3D viewing perspectives can be adopted to enhance the comprehension of the analyzed situation.

It is urgently necessary to develop practical programs for different purposes in the field of wastewater treatment. Now the design programs for grit chambers, anaerobic ponds, facultative ponds, aerobic ponds, aerated ponds and polishing ponds are being developed. Programs for automated plotting and man-machine interactive plotting are needed too. By using AutoCAD (Version 9.03 or 10.0), a secondary development of the softwares for engineering drawing of stabilization pond has been developed, which possesses the function of writing out explanatory notes. A program for writing out explanatory notes in Chinese is also being developed. In the process of developing such softwares, high-level language AutoLISP is used, so that the softwares possess artificial intelligence. Up to now the graphic softwares for plotting the general plan drawings and elevation drawings of grit chamber, various ponds, and pond systems have been developed.

碩士 國立臺灣科技大學 電機工程研究所 84 The paper presents the study of the computer aided industrial
power distribution system analysis and design based on the
AutoCAD environment. With the combination of graph and text,
graphic icon table of power distribution system elements can
provide the user a convenient way to draw the one line diagram
by clicking the graphic icon. Through the modification of
files, ACAD.MNU and ACAD.PGP, the application programs can be
linked with AutoCAD to execute the analysis of power flow,
three phase short circuit, voltage drop, and overcurrent
protection coordination. The advantages of the whole integrated
system is that the human errors and time wasting during the
edition of data files and the protection coordination route
will be avoided. As the graphic drawing and system analysis are
in the same environment, after the completion of one line
diagram, the results of analysis can be obtained to make
improvement at once. This will promote the design quality of
power distribution. The Borland C++ language is adopted in the
application programs linked with AutoCAD in this thesis.
Moreover, the application programs are proved to be efficient
and can be used in personal computer. Owing to the modulization
and portability, the C++ language is suitable to application
programs. In the mean time, for the subsequent adding of the
new various function to develop completely the computer aided
industrial power distribution system drawing, design and
analysis, this will provide the manager and aid industrial
power distribution system instruction.

Design education is important at technical universities and colleges. In general, real product design requires collaborative work. In this chapter, the authors discuss collaborative design education. An A360 cloud platform on Autodesk's 3D computer-aided design “AutoCAD” is adopted to illustrate a collaborative design activity implemented in the Engineering Graphics class offered at the College of Science and Technology, Royal University of Bhutan. By using A360 cloud, students can share a 3D model with group members. Based on feedback received, students can modify the initial model, share it, print, and discuss the modified object with members. This collaborative work allows students to create enhanced 3D design objects while engaged in discussions and interactions. The authors also discuss some difficulties encountered during the collaborative process and offer recommendations and future research ideas.

Abstract At SUNY College at Buffalo, a new course, TEC302, CAD/CAM, computer-aided-design and computer-aided-manufacturing was added to the Industrial Technology (IT) undergraduate curriculum in the fall of 1994. At that time, the technology department had been using the AutoCAD system for design/drafting, and SmartCAM for demonstrating computer-aided-manufacturing. SmartCAM is a sophisticated product that takes a great deal of training to use, does not work directly in AutoCAD, and with only four licenses, was not available to all the students. For these reasons, the author developed a CAM program, VAL-CAM, that works inside AutoCAD, and has most of the aspects of a more sophisticated CAM program, yet is simpler to use, is available to all students, and automatically generates CNC (computer-numerical-control) code suitable for driving the departments’ vertical milling machining center. This paper discusses the development of VAL-CAM, which is written in the AutoLISP language for compatibility with AutoCAD. The dialogue control language (DCL) of AutoCAD was also used for part of the user interface for VALCAM. The algorithms, flow diagrams, pseudo code and actual LISP code for some of the more interesting parts of the program are presented. VAL-CAM is under continuous development, and later sections of the program will be discussed in future papers.

Abstract A multiple objective function optimization design of straight bevel gearing with an advanced optimization method is described. The main parameters and geometric dimensions obtained with this algorithm are made use of to make computer parametric drawing of bevel gear in accordance with gear structure and by adopting currently high-level FORAUT interface software and the U. S.-made AUTOCAD autoplotting package, thus organically combining mechanical design calculation with the drawing of graphs. The said program is applicable to the optimization design of straight bevel gearing with arbitrary shaft angles and different pressure angles (α = 14.5°, 20°, 22.5°, 25°) to obtain ideal optimization parameters or engagement parameters, geometrical parameters and strength performance parameters and plot the correspnnding part working diagram. The results of application show that the system proposed is feasible, the algorithm explicit, the program operation reliable, convenient and flexible.

Abstract This paper presents a knowledge-base approach that assists a designer to evaluate possible process plans and associated costs based on tolerancing specifications of the designed part. It is an effort to take dimensional tolerances into computer-aided process planning (CAPP) for cylindrical parts through the usage of databases and knowledge bases. Geometric features with tolerancing specifications in a CAD system are first used to determine possible machining operations that can achieve the specified tolerances based on data from the machining feature database, the process precision grade database, and the precision grade database. Process plans are then generated based on rules and knowledge from process sequence knowledge base and the machining feature database. Possible process plans are further organized as a graph. Optimal process plan with least cost is then selected by searching through the graph. This is achieved based on machine set-up and operation costs that are derived from the machine tool resource database, the process parameter database, and the machine set-up and operation cost database. A CAPP software prototype supporting tolerance design on the AutoCAD platform is also demonstrated with examples to illustrate this approach.

3D design technology is the basis for the modern computer graphics. AutoCAD 2015 is a powerful version of computer-aided design system. We can solve complex tasks, without which this instrument can’t be solved in general. Using 3D design technology we not only save time working with a drawing. The geometric models are the foundation of the design basics, for working with drawing we can create projections, footnotes, sections and other modern graphics elements. AutoCAD can use and process the data from the model. This progressive design technology includes all parts of the design, starting from machine details, furniture and finishing with architectural forms of complex object models.

Abstract The geometric characteristics of three well-known movable octahedral 6R mechanisms are described and then, by matrix algebra method, we derive their general displacement closed-form solutions for further investigation and analysis. Based on the fundamentals of three dimensional analytical coordinate geometry, a systematic approach is offered to generate the configuration of movable octahedral 6R mechanism with the help of computer graphics. In addition, a user-friendly computer aided program implementing the process of generation synthesis can be developed in Autolisp, a Lisp language interpreter within autoCAD. The numerical results for every generation and their constrained motion are confirmed by the derived analytical solutions. The physical models of these synthesized mechanisms are also built respectively.

The method of characteristics (MOC) solves the neutron transport equation along each characteristics line. It is independent of the geometry shape of boundary and region. So theoretically, this method can be used to solve neutron transport equation in highly complex geometry. However, we should describe the geometry strictly and calculate intersect points of each characteristics line with every boundary and region firstly. In complex geometry, due to the great difficulty of treating of the arbitrary domain, the selection of geometry shape and efficiency of ray tracing are limited. So in most of the existing MOC codes, the type of outer boundary is limited as rectangular, hexagonal, triangular or the combination of them. And in order to treat reflective boundary condition, the selection of the azimuthal angles number is not freewill for different outer boundary shapes. To wipe off these limitations for using MOC in more complex fuel assembly calculation, the more powerful geometry treatment method is needed. The geometry treatment through the customization of AutoCAD, famous computer aided design software, is given in this paper. Thanks to the powerful capability of AutoCAD in graphics, the description of complex geometry becomes quite convenient. Moreover, with the language VBA (Visual Basic for Applications), AutoCAD can be customized to calculate intersect points of each characteristics line with every boundary and region. Thereby, no matter how complex or what kind of the geometry shape is, it can be treated uniformly by this method as long as it can be drawn in the AutoCAD. In addition, a directional interpolation method for the treatment of reflective boundary condition is introduced in this paper, so the number of azimuthal angles can be selected freely.

Within the scope of this lecture, the results of a teamwork project of the co-operating institutes are to be presented. The aim of the project is the optimization of the apparatus design by the development of an integrated computer support on the basis of a feature-based product model for apparatus engineering. For this reason the optimization on the one hand consists in the development of a computer-aided method for apparatus engineering and the corresponding tools and on the other hand, in the integration of the partial solutions into the commercial CAD systems AutoCAD and SolidEDGE. Due to the division into application and data model, the system can easily be adapted to user specific requirements without the need of programming the entire system again. With the aid of this system, the apparatus designer can be freed from routine activities and is able to dedicate more time for design according to safety precautions and load requirements.

Abstract This paper presents the innovative approaches that can be implemented in teaching descriptive geometry by using a Computer-Aided-Design-Drafting (CADD) software. Examples of line relations, line/surface relations, and plane/cylindrical solid intersections are given in the paper. The paper first discusses the principles of descriptive geometry, and then focuses on how these principles can be applied in a CADD environment. In addition, new methods that take advantage of CADD are also provided. The paper emphasizes creativity while solving descriptive problems by using a CADD software. Although all examples illustrated in CADKEY, the concepts revealed in this paper can be applied to other 3-D CADD software, such as AutoCAD 10 and will significantly improve the engineering student’s CADD skills.

Accurate, reliable and cost effective design of steel structures in heavy & medium engineering industrial sector plays a key role in the growth of industrial development. Objective is to get awareness about the difficulties faced by engineers / managers for reducing time to minimum level for preparation of drawings and other detailing work. New concept of detailed engineering techniques is introduced, which guides, how to customize design detailing stage and how to overcome (i-e optimize) delays to meet final production targets of the product in an Heavy Duty Engineering company specialize in the manufacturing of huge and massive steel structure frames. Design engineers must understand basic tools, methods, latest techniques which will be used for minimizing cost and time effect in the production of steel structures. Extensive knowledge of AutoCAD, AutoLISP for design and customization technique is required for the production drawing as output for shop floor. For sustainable engineering development, it becomes utmost important to utilize detailed engineering customization technique. This approach mainly governs on theoretical design approach, practical / on-the-job experience and computer aided design techniques. Use of all above approaches can lead to the successful achievement of efficient engineering optimization techniques / procedures. Because of complex and complicated nature of work of steel structures in Heavy Industries, it is essential to customize such work. Therefore it is suggested to use such methods for the mass production of steel structures on time and hence lot of time could be saved in heavy duty steel industries.
