手把手教你使用AIstructure-Copilot-V0.4.0的新功能：(1) 基于智能识图的CAD图纸前处理
0
引言
对不规范的CAD图纸，老版本的AIstructure-Copilot前处理操作繁琐，成为用户反馈的焦点问题。为此，V0.4.0版本引入了AI深度学习算法，实现了建筑CAD图纸信息的一键智能识别和提取，极大的方便了用户操作，本文我们将带领您体验这一全新的智能前处理流程。

CAD图纸前处理全流程操作
第一步：工程设计参数设置
AIstructure-Copilot-V0.4.0版本的工程设计参数设置界面更简洁、更直观。如图1所示，包括基本信息、楼层信息和信息校核三个菜单栏。其中，基本信息菜单栏中（图1a），用户需要输入项目名称、结构类型、抗震设防信息等参数；楼层信息菜单栏中（图1b），用户需要定义标准层和楼层组装信息，这里标准层参数可以选择程序默认的参数，也可以人为指定；信息校核菜单栏中（图1c），用户可针对已经输入的结构基本信息进行检查核对。

（b）楼层信息菜单栏
（c）信息校核菜单栏

第二步：基于深度学习的建筑构件识别
点击建筑构件识别按钮，将弹出图2所示对话框，点击“确定”后，用户可框选需要处理的标准层，软件将调用深度学习模型自动进行所有建筑构件的识别，整个过程大概需要1分钟。
图2 构件识别对话框
AI自动识别完成后，软件将弹出图3所示窗口，用户可点击“仅显示当前图层列表中的建筑构件”对识别结果进行检查和校对。同时，这里给出了自动识别的各构件所在的图层名称，用户可根据实际图纸信息，通过“获取图层名”和“移除图层名”功能，对不同构件分别进行增加和删除。
图3 建筑构件识别结果显示
第三步：智能识别结果校核
建筑构件识别完成后，用户需要执行“识别结果校核”操作，软件将自动对所有构件进行检查核对，找出可能存在问题的构件，在CAD图中红色高亮标出，并弹出如图4所示对话框。用户可针对具体构件，进行逐一或批量操作。
图4 构件识别结果校核对话框
第四步：建筑空间提取
用户完成识别结果校核工作后，点击“建筑空间提取”按钮，软件将提示用户框选需要识别的标准层，随后完成空间提取操作，结果如图5所示。本操作是识别图纸中的房间信息，为结构构件布置和获取楼面荷载提供数据。
图5 建筑空间识别结果
用户可通过右侧工具栏中的“修改空间”按钮，对自动建筑空间的识别结果进行修改和调整（图6），可以调整空间的功能属性，也可以针对识别过程中的错漏进行人工增减操作。

完成上述操作步骤后，前处理就完成了，就可以进入下一步智能设计的流程。
