Forge API查询BIM360 Revit文件转换结果缺失IFC衍生文件问题

我尝试直接转换BIM360中的Revit文件，相关代码和返回结果如下：

提交转换任务代码 #

List<JobPayloadItem> outputs = new List<JobPayloadItem> {
    new (JobPayloadItem.TypeEnum.Ifc)
};
string workFlowId = Guid.NewGuid().ToString();
JobPayloadMisc misc = new JobPayloadMisc(workFlowId);
JobPayloadDestination.RegionEnum destinationRegion = JobPayloadDestination.RegionEnum.US;
JobPayloadDestination destination = new JobPayloadDestination(destinationRegion);
JobPayload payload = new JobPayload(new JobPayloadInput(base64Urn), new JobPayloadOutput(outputs, destination), misc);

m_api.Configuration.AccessToken = accessToken;
DynamicJsonResponse response = await m_api.TranslateAsync(payload, true);

查询转换结果代码 #

DynamicJsonResponse result = await m_api.GetManifestAsync(base64Urn);

问题表现 #

返回的转换结果清单中没有IFC衍生文件的转换任务记录，返回内容如下（隐私信息已用*****替换）：

• 权限配置问题：BIM360项目默认禁止第三方应用导出IFC格式，需要项目管理员在BIM360管理后台开启对应项目的「允许IFC导出」权限，同时确保你的Forge应用已被该BIM360项目授权，且请求用的AccessToken包含data:write权限域。
• 转换请求参数缺失：仅指定输出格式为IFC不足以触发转换，需要补充IFC导出配置，比如指定Revit IFC导出版本、导出的视图/图纸范围等参数，示例配置如下：

  var ifcOptions = new Dictionary<string, object>
  {
      { "exportBaseQuantities", true },
      { "ifcVersion", "IFC2x3" },
      { "exportViewableId", "指定需要导出的Revit视图ID，可选" }
  };
  var outputItem = new JobPayloadItem(JobPayloadItem.TypeEnum.Ifc, ifcOptions);
  

• 强制转换参数逻辑问题：TranslateAsync的第二个参数为x-ads-force标识，设为true时仅当目标衍生文件不存在时才会触发转换，如果你之前提交过无效的IFC转换请求，可尝试删除现有manifest后重新提交转换，确保触发新的转换任务。
• 查询时机问题：返回结果中manifest状态为`inprogress
