结构工程师使用AutoCAD软件一般生成的是DWG文件，DWG文件在Allegro中是无法识别的，需要转换成DXF文件才能识别。如果不想麻烦结构工程师，可以自己安装AutoCAD进行准换。下图是结构DXF文件：

watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N0ZXJubHljb3Jl,size (95.2 MB, 下载次数: 0)

DXF文件搞定后，一般结构图都是公制mm为单位，而Allegro画图使用的是英制以mil为单位，所以打开Allegro软件需要把单位换成mm，如下操作：

watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N0ZXJubHljb3Jl,size (306.04 MB, 下载次数: 0)

watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N0ZXJubHljb3Jl,size (267.99 MB, 下载次数: 0)

设置完成后开始导入DXF：

watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N0ZXJubHljb3Jl,size (289.63 MB, 下载次数: 0)

选择DXF file ,DXF units设置为MM，然后点击Edit/View layers：

watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N0ZXJubHljb3Jl,size (274.12 MB, 下载次数: 0)

选择Select all,然后选择图层，Class选择BOARD GEOMETRY,Subclass一般我会新建立一个命名为2d-layout（个人习惯）：

watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N0ZXJubHljb3Jl,size (304.79 MB, 下载次数: 0)
设计完图层后，点击Map后显示出来设计的图层，然后点击OK：

watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3N0ZXJubHljb3Jl,size (324.38 MB, 下载次数: 0)

点击Import即可：

最终完成DXF导入：

.brd的单位可以不用设置成mm，只要导入的时候DXF的单位为mm即可

你好，我导入dxf时报错了，不知道怎么解决，请问可以帮忙看一下吗？
