如何使用Forge AutoDesk API從2d .dwg文件獲取元數據？

我正在使用Forge AutoDesk數據管理，設計管理和模型查看器API上傳我的.dmg，將其轉換爲svf，然後使用元數據。它適用於3D設計，但在使用2D設計時，元數據內部似乎沒有guid。有什麼我做錯了嗎？如何使用Forge AutoDesk API從2d .dwg文件獲取元數據？

編輯： 我能得到明顯的好了，但是當我獲取元數據一樣，它提供了一個空數組。

編輯在把一些其他的DWG文件，我得到這個消息作爲響應體的警告，可這也成爲一個原因，我無法獲得元數據？

您是否指定了2D輸出呢？ –

是的，在json中，我添加了2d和3d – alpheus

獲取元數據尚不可行的不幸2D文件。這已經記錄下來並將由開發團隊實施。

不幸的是，我們不能給你一個關於它的估計。好消息是壞消息。

我能想到的解決方法是將2D文檔加載到查看器中並獲取其屬性。否則，您需要下載以下提取示例所示的所有可見視圖，然後反向設計出來的sqlite db文件以查找這些屬性。

謝謝，我能夠獲取.db文件並查看數據，儘管它看起來可能在翻譯過程中丟失了一些 - 有可能嗎？另外，通過在查看器中加載文檔（你的意思是autocad？）以及如何從查看器中獲取屬性？ – alpheus

我的意思是查看器不是AutoCAD，但這取決於您的工作流程。一旦您在查看器中加載2D圖形，您可以使用viewer.getProperties（nodeId，...）來訪問每個組件屬性。 –

取決於「丟失」的含義...某些屬性可能無法從原始CAD文件中提取，例如AutoCAD實體上的XData –
