Question

我正在关注使用WebGL在浏览器中加载CAD文件的Autodesk tutorial，并且我正在尝试将我上传到其中一个存储桶的.nwd文件转换为“OBJ”。

但是，当我在上面的教程的第二步中运行POST请求时，我收到400（下面的完整响应），表示x-ads-troubleshooting: The system does not support this file format，尽管Autodesk documentation表示。{0}支持文件。

这是我文件的完整路径（需要Oauth令牌）：https://developer.api.autodesk.com/oss/v2/buckets/gathering-a-bulding-bucket/objects/Yale_Residential_Colleges_Arch.nwd

当我将项目添加到存储桶时，我获得了以下objectId（文档也称为源URN）：

"objectId" : "urn:adsk.objects:os.object:gathering-a-bulding-bucket/Yale_Residential_Colleges_Arch.nwd"

我对base64进行了编码，并根据文档删除了多余的填充（末尾的额外==字符），结果如下：

dXJuOmFkc2sub2JqZWN0czpvcy5vYmplY3Q6Z2F0aGVyaW5nLWEtYnVsZGluZy1idWNrZXQvWWFsZV9SZXNpZGVudGlhbF9Db2xsZWdlc19BcmNoLm53ZA

我现在正尝试使用以下命令将此nwd文件转换为OBJ：

curl -X 'POST' -H 'Authorization: Bearer OAUTHTOKENHERE' -H 'Content-Type: application/json' -v 'https://developer.api.autodesk.com/modelderivative/v2/designdata/job' -d '{"input":{"urn":"dXJuOmFkc2sub2JqZWN0czpvcy5vYmplY3Q6Z2F0aGVyaW5nLWEtYnVsZGluZy1idWNrZXQvWWFsZV9SZXNpZGVudGlhbF9Db2xsZWdlc19BcmNoLm53ZA"},"output":{"formats":[{"type":"obj"}]}}'

此命令产生以下响应：

有没有人对我可能会忽略的东西有任何线索？我很感激别人能提供的任何帮助！

Answer 1

请查看at this list of supported translations，您会看到不支持从.nwd到.obj的转换，仅支持svf（用于Viewer）。

Autodesk API：系统不支持此文件格式[.nwd文件]
