是否可以在Forge中获取已保存的nwd模型视图的名称？
问题描述 投票：0回答：1
我知道可以从Navisworks模型中保存的视图中获取摄像头，但是获取名称也很棒。将nwd文件上载到BIM 360文档管理项目时，会显示这些已保存的视图。是否可以使用Froge查看器执行此操作？或者这只是文件管理员的特色吗？关心Frode

Navisworks文件中保存的视图可以使用GET:urn/manifest响应中的视点名称获取。以下是Revit house样本模型的示例，rac_basic_sample_project.rvt导出为rac_basic_sample_project.nwc，请参阅文件夹类型folder JSON对象：

现在我们使用Kitchen视图来说明工作流程：

首先，让我们将它从原始模型空间转换为观察者的：
const nwVP = JSON.parse( // the above JSON );
const camera = nwVP.camera;
const nwVPName = nwVP.name;
const placementWithOffset = viewer.model.getData().placementWithOffset;
const pos = new THREE.Vector3( camera[0], camera[1], camera[2] );
const target = new THREE.Vector3( camera[3], camera[4], camera[5] );
const up = new THREE.Vector3( camera[6], camera[7], camera[8] );
const aspect = camera[9];
const fov = camera[10] / Math.PI * 180;
const orthoScale = camera[11];
const isPerspective = !camera[12];
const offsetPos = pos.applyMatrix4( placementWithOffset );
const offsetTarget = target.applyMatrix4( placementWithOffset );
const nwSavedViewpoints = [];
nwSavedViewpoints.push(
{
aspect: aspect,
isPerspective: isPerspective,
fov: fov,
position: offsetPos,
target: offsetTarget,
up: up,
orthoScale: orthoScale,
name: nwVPName
}
);
然后，切换视点
viewer.impl.setViewFromCamera( nwSavedViewpoints[0] );
最后，您可能知道上面转换的相机定义将具有与viewer.model.getData().cameras[1]几乎相同的值（浮动精度问题）
希望能帮助到你！
干杯，
切片映射的更新
如果您保存的视点包含剖面，则GET:urn/manifest的响应将具有以下内容：
{

-0.5950562340169588,
0,
-92.04215879314862
],
"status": "success"
}
sectionPlane属性是我们想要的目标。所以，转换是
const forge_model_offset = viewer.model.getData().globalOffset;
// assume the param of Navisworks clip plane is available
//I copied from the response of the GET:urn/manifest
const navis_clip_plane = { x: -0.803684066258349, y: -0.5950562340169588, z: 0,d:-92.04215879314862 };
//calculate exact distance in Forge Viewer
const dis_in_forge =( forge_model_offset.x * navis_clip_plane.x +
forge_model_offset.y * navis_clip_plane.y +
forge_model_offset.z * navis_clip_plane.z) + navis_clip_plane.d;
const cutplanes = [
new THREE.Vector4( navis_clip_plane.x, navis_clip_plane.y, navis_clip_plane.z, dis_in_forge )
];
//apply the plane to sectioning
viewer.setCutPlanes( cutplanes )
