1、The Architectural Charting and DrawingRecognition The architectural engineering plat is one kind of the engineering plat, which is used to express the shape, size, material, structure, construction mode of the building as well as the specification and so on1. It is not only an important tool to expr

5、 will leave a shadow on the ground or on the wall. By scientifically and abstractedly summarizing the relationship between object and shadow in the long-term production practice, people sum up the method of projection. The projection is widely used to express the object in the engineering circle, so

In the ordinary circumstances, three-plane projection drawing is compo

9、sed of the horizontal projection drawing, the frontal projection drawing and the profile projection drawing. In the analysis process of three-plane projection drawing, we are required to follow the projection relation of “equality in height, width and length”, which is the foundation of drawing and

Some people use it for “computer-aided

13、drawing”, while others for “computer-aided design”. There are now many CAD systems available to design organizations. They vary in cost, scope, capability, and in suitability for the work of the particular office. acronym縮寫詞available可利用的capability性能 第14頁/共25頁 There is a long history of using compute

14、rs particularly in an engineering design office, and it has mainly been for elaborate calculation such as structural analyses, and for administrative chores3. Such tasks are essentially operations on numbers, and which is ideally suited for computers. However designers tend to communicate most proje

15、ct information in graphical forms. Drawings have always been central to the whole construction process, and are likely to continue as such in the foreseeable future. elaborate闡述foreseeable可預(yù)見性的第15頁/共25頁 It has taken some time to teach computers to cope with information in graphical form. But the inc

16、entives are evident. A design office might typically spend only 5 or 10% of its collective effort on calculations. However the production of drawing might well represent 40% or more of its total workload. So any important that can be achieved in drawing efficiency ought to have a high impact. This u

17、ndoubtedly accounts for much of the huge current interest in CAD. Now, we understand the CAD graphics interface 第16頁/共25頁 Fig. 2.7 the CAD graphics interface 第17頁/共25頁 Automatically plotted drawings produced as a by-product of an engineering applications program are no recent achievement .As an exam

18、ple, if we examine highway design, we find that in the late 1960s and early 1970s the geometry of most important new roads was being drawn by computer4. Plans, sections and perspective drawings of roads could be produced automatically. However the particular programs used were limited in scope to ro

They worked least well for complex road interchanges in the urban environment. Although they re

20、main immensely valuable, such programs would not be classified as CAD systems because they lack a capability for interactive graphics. They do not permit the designer to carry on a dialogue with the computer to gradually build up, refine and modify his design information. interchange互通式立交；交通立體交叉refi
