Forge Design Automation超时求助：AutoCAD Core Console因超时关闭

使用AutoCAD版Forge Design Automation执行任务时，出现「AutoCAD Core Console is shutdown due to timeout」错误，任务最终执行失败，运行报告如下：

问题分析 #

从日志可见，执行DETECTIONCMD命令后刚好1分钟触发超时，核心原因包括：

• DETECTIONCMD命令逻辑存在性能瓶颈，无法在默认超时窗口内完成执行
• 命令可能陷入死循环、等待交互输入，或处理的CAD文件过于复杂/庞大
• 命令执行过程中出现未捕获异常，导致进程挂起无响应

解决方案 #

• 优化命令逻辑：检查DETECTIONCMD是否存在冗余计算、死循环，拆分大任务为多个小步骤执行，降低单次计算负载
• 调整超时阈值：在Forge Design Automation工作项配置中，延长AutoCAD核心引擎的超时时间（需注意平台最大限制，合理设置）
• 预处理CAD文件：清理文件中无用对象、块、图层，简化复杂模型后再提交任务
• 增加日志输出：在DETECTIONCMD中添加关键步骤的日志打印，定位具体卡顿环节
• 确保命令无交互：确认命令全程自动化，不存在等待用户输入的逻辑
