使用APS Model Derivative API转换SVF2文件不完整问题排查

问题现象 #

• 使用APS Model Derivative API将复杂Autodesk Inventor模型转换为SVF2格式，部分模型转换正常，但多数模型丢失部分或全部组件，部分模型查看时弹出「Model is Empty」窗口：
  
• 即使模型转换后完全为空，任务仍返回成功结果
• 将原装配体中无法显示的文件加入其他装配体后，SVF2可正常显示，说明问题与几何形状无关

疑问 #

是否有额外的任务输出可供查看，以定位失败的位置和原因？

补充信息（编辑） #

使用PowerShell完成文件上传与任务提交，脚本如下：

$clientSecret = "[REDACTED]"
$bucketName = "[REDACTED]"

    }
    
    $uri = 'https://developer.api.autodesk.com/authentication/v1/authenticate'

已尝试的解决方法 #

• 确保所有文件迁移至同一版本的Inventor
• 消除建模错误
• 验证装配体在Inventor中可正常打开且无问题
• 暂未尝试完全重建装配体
