我尝试在控制台中输入:让a = NOP_VIEWER.getState().

I try input in Console: let a = NOP_VIEWER.getState().

，然后:NOP_VIEWER.restoreState(a).

and then: NOP_VIEWER.restoreState(a).

结果是相同的，所以我认为这个问题可能在getState函数上.

the result is the same, so i think the question maybe on the getState function.

使用'Autodesk.Viewing.MarkupsCore'扩展程序进行2d绘制，读取保存的标记数据，然后绘制丢失的颜色.我尝试了三个以上的绘制，但是结果是相同的.而且即使退出标记，绘制也不会恢复为原始形状.

Use 'Autodesk.Viewing.MarkupsCore' extension for 2d draw, read the saved markups data and then draw lost color.I have try more than three draw, but the results were the same. And the draw won't be restored the original shape even exit markup.

function loadMarkup() {
  model_viewer.loadExtension('Autodesk.Viewing.MarkupsCore').then((markupsExt) => {
    markup = markupsExt
    model_viewer.addEventListener(Autodesk.Viewing.Extensions.Markups.Core.EVENT_EDITMODE_CHANGED, function (event) {
      console.log(event)
    })
    markup.enterEditMode()
  })
}

function saveMarkup() {
  // 将刚刚产生的标注涂丫转换成字串
  const markupsPersist = markup.generateData()
  // 当前画面的状态 (zoom, direction, sections)
  const viewerStatePersist = model_viewer.getState()
  markup.leaveEditMode()
  markup.hide()
  console.log(markupsPersist, viewerStatePersist)
  Cookies.set('markupsPersist', markupsPersist)
  Cookies.set('viewerStatePersist', viewerStatePersist)
  // model_viewer.restoreState(viewerStatePersist)
  // setTimeout(() => {
  //   markup.show()
  //   markup.loadMarkups(markupsPersist, 'aaa')
  // }, 3000)
}
function loadMarkupHistory() {
  let svg = Cookies.get('markupsPersist')
  let view = Cookies.get('viewerStatePersist')
  model_viewer.restoreState(JSON.parse(view))
  setTimeout(() => {
    model_viewer.loadExtension('Autodesk.Viewing.MarkupsCore').then((markupsExt) => {
      markup = markupsExt
      markup.enterEditMode()
      markup.leaveEditMode()
      markup.loadMarkups(svg, 'aaa')
    })
  }, 500)
}

在loadMarkupHistory()图像之后: screenshot2 ，

after loadMarkupHistory() image: screenshot2, screenshot3

推荐答案

该颜色被隐藏，因为viewerState对象具有以下属性:孤立. 将隔离的设置为空数组将解决问题

the color was hide because of the viewerState object has a property: isolated. set the isolated to an empty array will resolve the problem
