Question

致命错误：未处理的访问冲突在 1d8257a5h 读取 0x0008 异常

失败的缺失输出

Answer 1

我终于让它在本地 AutoCAD 中与 HostApplicationServices.getRemoteFile 一起工作，然后将其迁移到 Design Automation。它现在也在工作。下面是.NET插件的命令。

为了进行简单的测试，我在插件中硬编码了 URL。您可以将 URL 替换为您身边的工作流（通过 json 文件或 Design Automation 的输入参数）

我的演示 ReadDWG 从远程 URL 文件中读取实体，然后将实体 wblock 到当前图形（HostDWG），最后保存当前图形。

希望它有助于解决您身边的问题。
