Question

我已经遇到过this post，它有一个非常相似的问题。

我的问题是，在确保所有链接正确无误且拼写正确之后，我仍然无法弄清楚为什么按钮没有出现。我还添加了一个24x24px的自定义hashcode。

下面是我的img/icon.png，index.html，ForgeViewr.js和MyAwesomeExtension.js

谢谢您的帮助！

Here is a screenshot of the current toolbars that appear when I build the project as is.

Answer 1

尝试直接使用Viewer3D而不是ViewerApplication注册扩展。我的扩展程序或Html / CSS看不到其他任何内容，并且以下内容运行良好：

  var viewer = new Autodesk.Viewing.Private.GuiViewer3D(myViewerDiv,{ extensions: ['MyAwesomeExtension'] });
