The Development And Application On The CAD System Of Ornamental Stone

Along with uninterrupted consummation of the CAD technology, the developed special CAD, which is faced the objects, is popular in the company. But in the industry of stone manufacture, the development of CAD technology has lagged behind that in others industries. According to the need of the corporation, this subject mainly used VB/VBA language to carry secondary development.Due to the particularity of stone revolving staircase, this subject studies three kinds of familiar staircase: radial revolving staircase, unradial-homocentric revolving staircase and unradial-inhomocentric revolving staircase. It can realize auto-partition and serial numbers. The important part is that it can realize parameterized design of footplates and fore-footplates. Before drawing the pictures, it needs to analyse geometry relations and detrude the needed formulas. They used parameter drawing technology to compile applied programs. The users can gain the needed drawings easily through change the parameters of staircase. At the same time, the labels would be lined out. So it is not only convenient but also fast. It can enhance drawing precisions. The traditional drawings existed many deficiencies, for example, the period of design is long. It solves those problems.There are some researches on stone layed, auto-added numbers and work sheet made. According to the standard of Country Architecture Material Industrial Department, at the section of laying stone, institute some projects of partition, which is often used in the company. The users can elect the right projects and transfer the programes to add the numbers. At last, the users can do some modules from the layed area to output work sheets.
