利用FME创建CAD标准图层模板

阅读更多关于利用FME创建CAD标准图层模板

在我们FME的博客资料里面，介绍了关于利用FME和Excel表格如何在GIS环境中生成标准数据结构的方法，那下面为大家介绍一下利用FME和Excel表格结合Python脚本如何在AutoCAD环境中生成标准图层的方法。你拿到的CAD数据生产标准可能是下面这样的，图层太多，线性太多，颜色太多，一个一个建立你会头痛。你需要确定计算机环境中是否正确安装了FME Desktop软件、AutoCAD软件以及能生成Excel表格的软件。安装Python模块pyautocad的运行环境，下载pyautocad模块包并安装。在python编译器中运行“import pyautocad”，确保该模块成功安装并可用。将生产标准规范化到Excel表里面备用使用FME Desktop读取标准规范化后的 Excel表，利用AttributeCreator将CAD图层名称、线性、颜色等字段内容进行重命名。设置FME中python脚本的运行环境，在FME Desktop左侧导航栏中工作空间参数下找到“Python Compatibility”,文中涉及的pyautocad模块安装路径在ArcGIS的python路径中，因此，选择 “Esri ArcGIS Desktop(Python 2.7)”（如果用户你安装在其他路径中

How to call a async function from a synchronized code Python

问题 So I'm locked to a python 3.6.2 interpreter that follows my desktop application. What I want is to call an async function from a synchronized method or function. When calling the python function from the desktop application it has to be a normal function which can not be awaited. From the desktop application I am able to send a list of urls, and what I want is to send back response from every url in an async matter. here is my try I've marked the SyntaxError which I don't know how to bypass.
