首先用AutoCAD画一个图,然后导出为DXF格式。 这个图有两个图层,图层0和自定义的Mylayer。图层0有一些线段,图层Mylayer有一个圆和一个圆弧。 dxfgrabber可以读取多个版本的DXF,这里,把这个工程保存为R12 DXF,起名为『mydraw.dxf』 importdxfgrabberdxf=dxfgrabber.readfile("mydraw.dxf")forlayerindxf.layers:print(l...

dxf.readfile("example.dxf") 遍历所有图层 for layer in dxf.layers: print("Layer name: ", layer.name) 遍历图层中的所有线段 for line in layer: print("Line: ", line.start, line.end) 使用ezdxf库读取.dwg文件 1、安装ezdxf库 我们需要安装ezdxf库,可以通过pip进行安装: ...
filename = "example.dxf" # 替换为你的DXF文件路径 dxf = dxfgrabber.readfile(filename) ``` 4.计算参数: 根据具体需求,我们可以使用DXF文件中提供的实体对象来计算不同的参数,如长度、面积等。 -计算长度: ```python length = 0 for entity in dxf.entities: if entity.dxftype == "LINE": length ...
break line2 = linetemp line1 = line file.close() if __name__=="__main__": file = open("D:\\test.dxf") reader = DxfReader(file) reader.readDXF() for temp in reader.pointList: print str(temp.x) + " " + str(temp.y)...
3.dxfgrabber模块导入后,在项目中使用dxfgrabber.readfile()方法打开cad文件,并创建文件对象; file = dxfgrabber.readfile(D:\User\test.dxf)复制代码 4.最后,文件打开后,使用layer方法即可获取到cad文件内容; for layer in file.layers: print(layer.name,layer.color,layer.linetype)复制代码 0 赞 0 踩最新...
