The General Layout Theory Of Three-dimensional And Its Applied Research

With the development of three-dimensional design software technology,its efficient design and compared to the use of human-computer graphics now,in terms of quality and speed of speaking,have a distinct advantage.In this paper,based on the general layout theory,combination of the three-dimensional advanced software design technology,raised general layout of three-dimensional and methods,and made a interpretation and proof to the three-dimensional general layout theory through the specific examples of relevant parts of the general layout of the application.The purpose is to find three-dimensional design methods of general layout;it can significantly improve the design efficiency and design quality of results and applications to quickly input.This article applies CIVIL3D which is Civil Engineering software to the general layout of three-dimensional and uses three-dimensional examples to verify the feasibility of the general layout and the advantages and disadvantages.The paper of the research are as follows:First of all,the use of digital elevation model(DEM) data to establish the original natural terrain model,and its elevation,slope,watershed analysis;. followed by the design of ground slope to deal with in terms of earthworks and Airport civile3d applies to short-,medium-,long-term land-use planning;Use Google earth date and civil3d software to build up DEM of mountain,To establish the three-dimensional road modeling and use it to design;Finally establish the machine repair shop building model and demo animation.Through the above-mentioned studies,the following conclusions be made:the 3d general layout is the development trend in the future;Applies civi3d software to the three-dimensional general layout has the practicality and feasibility;The establishment of the original natural surface model,through triangulation calculation to carry out earthworks,which greatly reduces the amount of earthwork calculation and the error rate;plant after three-dimensional modeling of mountain roads,road design in the vertical section and cross-sectional data were extracted tedious work can be completed in an instant and can be generated in accordance with the requirements of road construction plans.Through the example of three-dimensional machine rapier factory model and the animation of demonstration,results for the general layout of a higher level of diversity and show the results of possible.The general layout of three-dimensional is to use intelligent software drawing the working drawings,the design work and a plan to separate the great graphics to reduce the red tape so that designers can allocate more energy to the design.In the three-dimensional design environment,designers can simulate a computer screen designed by the actual situation in various aspects of the design advantages and problems of evaluation.Enhance the design and reliability of the scientific and timely identify and correct the design stage is not easy to detect errors before the design is completed in its optimized design scheme so as to enhance the feasibility and practicality,improved efficiency,design cycle shortened significantly.
