基于AutoCAD软件的智能建筑空间结构视觉设计

AutoCAD⁃based visual design of intelligent building spatial structure

智能建筑空间网格结构造型设计是总体空间结构视觉设计的关键环节。采用AutoCAD软件设计智能建筑空间结构,将ObjectARX作为AutoCAD软件的二次开发工具,通过排样数据的生成优化以及排样数据向图形转换并绘制实现AutoCAD软件的二次开发。在二次开发的AutoCAD软件中通过前处理模块输入智能建筑空间网格图形、支座以及节点荷载,形成总体数据文件,内力分析及设计模块利用该文件实行计算。得到智能建筑空间的结构内力数据及截面面积后,采用后处理模块在二次开发的AutoCAD软件下得到智能建筑空间结构视觉的内力和杆件截面图,并在AutoCAD软件界面导入图形,构建智能建筑空间结构视觉模型。经实验分析,该设计方法设计效率高,出图时间快,且设计的空间结构视觉模型图透视效果、识别度、图形比例效果都较好。

The intelligent building space grid structure modeling design is a key step of the overall space structure design.The AutoCAD software is adopted to design the intelligent building space structure.The ObjectARX is taken as the secondary development tool of AutoCAD to achieve its secondary development by layout data′s generation and optimization and their pattern transforming and drawing.The intelligent building spatial grid patterns,bearings and node loads are input into the secondly⁃developed AutoCAD by pre⁃processing module to form the overall data file,by which computation about internal force analysis and design module is implemented.After getting the structure internal force data and cross section area of the intelligent building space,the internal force and bar section from the perspective of intelligent building spatial structure is obtained with the post⁃processing module under the condition of secondly⁃developed AutoCAD.And then,the pattern is imported into the interface of AutoCAD to construct intelligent building spatial structure visual model.Experimental analysis shows that the designed method has high design efficiency,short drawing time,and better perspective effect,recognition degree and pattern scale effect of the designed space structure visual model diagram.
