Principles and Operation Points of Two-Dimensional CAD Collaborative Drawing in Architectural Design
Based on the essence of two-dimensional architectural drawing,this paper analyzes the limitations and advantages of two-dimensional CAD drawing design method.By comparing the differences between 2-D CAD drawing design method,3-D building information model and architectural parametric design method and their respective advantages and disadvantages,the advantages of collaborative drawing are analyzed in principle,that is,the correlation and uniqueness of graphic objects are built by referring to drawing method,so as to improve drawing efficiency and reduce error rate.This paper introduces some operation points of 2-D CAD drawing,takes planar graph as an example,expounds the basic method of splitting parts drawing,analyzes the characteristics and applicable objects of several drawing tools,such as reference,block and layer.
