如何使用 Forge AutoDesk API 从 2d .dwg 文件获取元数据？

Question

我使用 Forge AutoDesk 数据管理、设计管理和模型查看器 API 上传我的 .dmg，将其转换为 svf，然后使用元数据。它适用于 3D 设计，但当我使用 2D 设计时，元数据中似乎没有 guid。我做错了什么吗？

编辑： 我可以得到清单，但是当我获取相同的元数据时，它给出了一个空数组。

Answer 1

不幸的是，获取元数据对于 2D 文档尚不可行。已记录为愿望，将由开发团队实施。

很遗憾，我们无法为您提供关于 it.Sorry 坏消息的估计。

我能想到的解决方法是在查看器中加载 2D 文档并获取其属性。否则，您将需要下载下面提取示例公开的所有可视项，然后对随附的 sqlite db 文件进行逆向工程以查找这些属性。
