使用 autodesk forge api 获得 "mass properties" 但一无所获
use autodesk forge api to get "mass properties" but got nothing
使用 autodesk forge api，首先我得到一个 access_token 并创建一个 bucketkey，然后上传一个 stl 文件，然后验证作业是否完成，然后得到 guid。使用 access_token, urn , guid I post 调用 :
curl -X 'GET' -H 'Authorization: Bearer

感谢任何帮助，谢谢 whosebug.com。
此端点只是 returns 从本机种子文件中提取的属性，它不会为您计算质量、体积等。我不认为这些物理属性是 STL 文件的一部分，因此您也不会在 /properties 端点看到它们。
如果您上传 Inventor 或 dwf 文件，您将看到附加到该文件的属性。要进行简单测试，请将您的文件上传到我们的查看器 https://a360.autodesk.com/viewer 并使用属性面板查看可用的属性，您将从端点获得的属性相同。
希望对您有所帮助
