Research On 3D Architecture Design System Based On AutoCAD Platform

At present,Architecture is very important in the field of flow plant industry both at home and abroad.It can not only complete the large,medium and small sized construction projects,but also provide the basis for the reference model for the specialties of the technology piping,HVAC and Cable.Nowadays,most of the two-dimensional drawings are used in China,and the vertical section drawings need to be plotted separately.The three-dimensional model is generated from the information of two-dimensional plane map,and the process of turning the mold will waste a lot of time.BIM technology is widely used in foreign countries.BIM contains information in all stages of design,construction and operation management,and all kinds of information are always built in a three-dimensional model database.It not only saves the time to do the project,but also ensures the correctness and consistency of the data.The research of this project hopes to improve the efficiency of the designer and improve the design,construction and operation of China’s process factories to the advanced level of the world.The issue of the use of ObjectARX package was developed based on the AutoCAD platform,to industrial building components commonly used standard atlas based construction of component library of 3D parameters,a three-dimensional model of the main building components by using the modeling method conform to the user habits,and use the IFC standard to save the data,to establish the relationship between the walls,columns,beams,including support,door,window,holes and other components.The 3D model built can be quickly generated automatically to meet the construction requirements of the flat vertical profile drawing,ensure the consistency and correctness of data,the construction of professional design work standardization,improve the reusable architecture design document rate and improve the design efficiency,documentation control and improve the construction of professional design the quality of the document architecture.
