Forge是什么 为什么能够渲染出来rvt模型
Forge是由Autodesk开发的一套云端开发平台和工具集。在Forge平台中有一个名为Model Derivative的服务它可以将包括RVTRevit在内的多种BIMBuilding Information Modeling文件格式转换为可在Web上浏览和渲染的格式。具体来说Model Derivative服务可以将RVTRevit文件转换为SVFScalable Vector Graphics格式。SVF是一种基于Web的轻量级3D模型表示格式可以实现高性能的3D模型渲染和交互。通过将RVT文件转换为SVF格式可以在Web端使用Forge提供的Viewer组件加载和展示RVT模型
Forge与Autodesk的关系
Autodesk是一家设计软件公司Forge可以视为Autodesk的云端扩展
渲染步骤
首先要注册autodesk平台并创建项目 获取自己的client_id与client_secret 官网地址Autodesk Platform Services (formerly Forge) 如下图
配置postman环境
下面我们演示通过postman上传模型到Forge云端然后配置Forge的js渲染出来

} client_secret与client_id记住改成自己的然后就开始用postman请求上传了
获取access token https://developer.api.autodesk.com/authentication/v1/authenticate 是用于获取 Autodesk API 的访问令牌access token的认证
请求中包含必要的认证信息
客户端 IDclient_id客户端密钥client_secret grant_type授权类型通常为 client_credentials客户端凭据模式scope请求的权限范围用空格分隔多个权限如 data:read data:writeexpires_in设置合适的过期时间单位毫秒
响应结果
创建 Autodesk Forge 中的存储桶bucket https://developer.api.autodesk.com/oss/v2/buckets 请求中包含必要的认证信息:
AuthorizationAuthorization: Bearer {{access_token}}bucketKey存储桶的唯一标识符它必须是全局唯一的。可以使用小写字母、数字、连字符 - 和下划线 _ 来命名。长度应在3到128个字符之间。policyKey存储桶的访问策略。默认为 transient表示存储桶中的对象在30天后过期 persistent表示永久保存 响应结果 查看bucket是否创建成功 https://developer.api.autodesk.com/oss/v2/buckets 请求中包含必要的认证信息:
AuthorizationAuthorization: Bearer {{access_token}}
请求可选的参数信息:
limit指定要返回的存储桶数量的限制。例如返回最多 10 个存储桶默认为 10 响应结果 往bucket里放置object模型 https://developer.api.autodesk.com/oss/v2/buckets/{bucketKey}/objects/{objectName} 请求中包含必要的认证信息:

AuthorizationAuthorization: Bearer {{access_token}}bucketKey查询的存储桶的实际标识符 响应结果 将模型在云端转换成SVF格式 https://developer.api.autodesk.com/modelderivative/v2/designdata/job 请求中包含必要的认证信息:
AuthorizationAuthorization: Bearer {{access_token}}input指定要转换的对象的 URNUniform Resource Name。将 object_id 的 URN 作为输入。output指定要生成的输出格式和文件类型。在这里你可以指定 SVF 格式作为输出。例如{formats: [{type: svf, views: [2d, 3d]}]}
备注input中的urn是 objectId转化为Base64格式
响应结果 检查模型是否转化完成 https://developer.api.autodesk.com/modelderivative/v2/designdata/{base64_urn}/manifest 请求中包含必要的认证信息:
AuthorizationAuthorization: Bearer {{access_token}}base64_urn经过 Base64 编码的 URN
