Autodesk Forge 从转换后的 DWG 获取清单和元数据

【中文标题】Autodesk Forge 从转换后的 DWG 获取清单和元数据

【英文标题】：Autodesk Forge getting Manifest and Metadata from converted DWG

【发布时间】：2016-11-23 21:23:35

【问题描述】：

我的目标是将 DWG 文件转换为可在 Forge Viewer 中使用并具有标记。 在获取所有正确文件以使用脱机查看器的过程中，我正在尝试获取文件的清单和元数据。我想要元数据，以便我可以访问多边形 ID 以进行标记。当我调用元数据时，它是空的。我做错了什么？

我已经上传并发送了一个 DWG 文件的 SVF 转换作业请求。

请注意，使用 node.js 提取器示例它适用于同一个文件，并且提取器会创建 manifest.json.gz 和 metadata.json.gz 。我只是想了解那些是如何创建的以及使用哪些 REST 调用的。

【参考方案1】：

很遗憾，模型衍生 API 尚不支持 2D 文档的元数据，例如 .dwg。我们正在努力在即将发布的 API 版本中提供此功能。

目前我想唯一的解决方法是下载软件包并“逆向工程”内容。你可以看看我的 NPM 包download method implementation，它仍在使用 v1 API，但可以正常工作。这应该让您了解如何下载 svf 资源。

【讨论】：

谢谢菲利普。当您说“下载软件包”时，您指的是什么？您是在谈论来自提取器的 zip 文件，还是我可以进行单个 REST api 调用，它将为我提供与包（zip）中转换后的文件相关联的所有内容？

不，遗憾的是没有单个 REST 调用，因为该 API 并非旨在提供下载功能，它旨在加载到查看器中，但是我的 NPM 包“下载”方法使在本地下载 zip 非常容易，它是一个方法调用。它基本上反转了查看器在加载 URN 时所做的事情，而不是在浏览器中加载文件，而是保存在磁盘上。我们不提供在本地读取或修改这些文件的 API，但这样做非常好。它只是没有记录，我们不保证 svf 格式在未来永远保持不变......

菲利普·里夫斯玛。在你的提取程序上，当它获取所有文件时，你能告诉我 .sb 和 bin 文件的来源吗？我不知道你是如何得到它们的。我提取的 rvt 文件的示例位于文件夹 Resource\3D_View_3D_\0.pf...6pf、CameraDefinitions.bin 中。我没有在我得到的清单 json 中看到它们。

您是在谈论github.com/Developer-Autodesk/view-and-data-npm 的 npm 包吗？您可以查看 is 包（1 个文件）的源代码并在其中放置跟踪信息。看看下载方法（github.com/Developer-Autodesk/view-and-data-npm/blob/master/…）。这是一个多步骤的过程：1/ 解析可视数据，2/ 下载第一组项目，3/ 解析我们获得的清单，4/ 下载第二组项目。我不知道确切的时间下载了哪个项目，但是通过放置日志并运行测试，您应该很容易找到。祝你好运

嗨@PhilippeLeefsma，很抱歉再次提出这个话题。 API 是否仍然不支持 .DWG 文件的元数据？我知道这个答案有点老了，但想知道，有什么改变吗？
