Study On Data Process And Visualization Of Building Deformation Base On AutoLISP

The CAD software, AutoCAD, is in fast developing and exploring. AutoCAD can be used in many areas for improving the design efficiency, optimizing projection, lighting labor intension, shorting design period and intensifying the standardization. The special opening framework had made AutoCAD being used in many industries, such as machine, electron, space flight, chemical engineering, architecture, measure and prospecting. It has changed the design trend to digitizing and no paper.A program for the data process and visualization of building deformation is proposed in this paper. The program is based on the AutoCAD developing platform. At first, this paper introduces AutoLISP language about making course of menu and preparing methods of line type in detail. Secondly it narrated the concrete method of CAD symbol storehouse. The making of the symbol storehouse can divide into two parts: making of independent symbol and making of line type. The making of Independent symbol through writing procedure with AutoLISP language. To make use of the independent symbol is by transferring the realize menu and to set up symbol storehouse for making of line type is an essential part. It is divided into simple line type and complicated line type. The author introduces emphatically the process of making complicated line type and introduces the method about making the type document that included in the line type. Thirdly by making use of the procedure that developed under the CAD in the concrete project, the thesis showed that the procedure could easily express the deformation of the buildings. Finally a mathematic model of deformation amount about high building for statistic analysis was established. The stability of high building in the processes of construction and management was discussed and it based on the analysis and comparison of the observed data.
