透過程式碼第二行綁定隔離事件和自訂函數

var instanceTree = _viewer.model.getData().instanceTree;

_viewer.addEventListener(Autodesk.Viewing.ISOLATE_EVENT,colorIsolate);
      
function colorIsolate(){
  var rootId = this.rootId = instanceTree.getRootId();
  var allobjects=getAlldbIds(rootId);
  _viewer.restoreColorMaterial(allobjects);
  _viewer.setColorMaterial(_viewer.getIsolatedNodes(),0xff0000);  
}

function getAlldbIds (rootId) {
		var alldbId = [];
		if (!rootId) {
			return alldbId;
		}
		var queue = [];
		queue.push(rootId);
		while (queue.length > 0) {
			var node = queue.shift();
			alldbId.push(node);
			instanceTree.enumNodeChildren(node, function(childrenIds) {
				queue.push(childrenIds);
			});
		}
		return alldbId;
	}

測試：綁定點擊事件與變色函數，將點選物件變色

NOP_VIEWER.addEventListener(Autodesk.Viewing.SELECTION_CHANGED_EVENT, Onselectchange);

function Onselectchange(){
var selected = NOP_VIEWER.getSelection();
NOP_VIEWER.restoreColorMaterial(selected);
NOP_VIEWER.setColorMaterial(selected,#bacfef); 
}

遇到問題最可怕的不是被問倒，而是自己選擇逃避
