这个问题可以通过在加载模型时添加bubbleOverlays: true参数来解决。例如：

var viewer;
var options = {
    env: 'AutodeskProduction',
    getAccessToken: function(onTokenReady) {
        var accessToken = 'YOUR_ACCESS_TOKEN';
        var expireTimeSeconds = 60 * 30;
        onTokenReady(accessToken, expireTimeSeconds)
    },
    api: 'derivativeV2',
    bubbleOverlays: true // 添加bubbleOverlays参数
};

Autodesk.Viewing.Initializer(options, function() {
    viewer = new Autodesk.Viewing.GuiViewer3D(document.getElementById('viewer'));
    var documentId = 'YOUR_URN';
    Autodesk.Viewing.Document.load(documentId, function(doc) {
        var viewables = doc.getRoot().getDefaultGeometry();
        viewer.loadDocumentNode(doc, viewables).then(function(result) {
            console.log('加载完成');
        });
    }, function(error) {
        console.log('加载失败');
    });
});
