Utilizing the interface of ActiveX Automation between VB and AutoCAD R14, this thesis provides a kind of way to solve the problem of providing drawing environment in the of Engineering Drawing CAI software, and the problem of giving intelligent judgement of adding lines and drawing the third view.
Based on the study of the “laser light magnifier bearing device”, the CAD optimization-design technology of exact mechanism is discussed and the design of "magnifier bearing device" by using CAD software "PRO/E", CAE software "ANSYS" and engineering drawing software "AUTOCAD" as the optimization- design tool is accomplished.
Then, the HOQ (house of quality) concept of the QFD (quality function deployment) is extended as a tool for software description based on the similarity between HOQ in quality design and engineering drawing in product design.
然后根据质量设计中的质量屋HOQ(house of quality)与产品设计中的工程图之间的相似性,将质量功能展开QFD(quality function deployment)中的质量屋HOQ概念扩展成一种软件描述工具,并引入H. A.
To make separately use of Visual Basic 6.0,Visual FoxPro 6.0 and Visual LISP develops mechanical design computation,mechanical engineering database management and mechanical engineering drawing autodrft application programming modules.
The main contributions are included as follows:The first, Meta-data technique is introducted into the field of drawing files management, and the overall structure scheme of "Engineering drawing files management system based on AutoCAD 2000" is proposed.
Software modules are designed to generate a process plan or several plans for a new part according to the input data from its engineering drawing.
In this paper, the problem of 3D-object model reconstruction from engineering drawing projections is analysed, and its main stages are shown.
Process planning is the function within a manufacturing facility that establishes the machining processes and parameters to be used so as to convert a piece-part from its initial form to the final form predetermined on an engineering drawing.
Accurate arc segmentation, essential for high-level engineering drawing understanding, is very difficult due to noise, clutter, tangency, and intersections with other geometry objects.
This article presents a new thinning algorithm particularly well suited to handwriting characters or engineering drawing images.
