Autodesk Forge 扩展

Question

所以我按照本教程来扩展 Autodesk Forge 查看器。我已经完成了所有步骤，但没有显示任何按钮，我认为这是由于加载错误造成的。

https://forge.autodesk.com/blog/extension-skeleton-toolbar-docking-panel

我也试过这个教程，有同样的问题：

http://learnforge.autodesk.io/#/viewer/extensions/selection?id=conclusion

我的问题是我没有收到错误，只是没有显示扩展...有人知道为什么吗？

我假设查看器或索引中存在错误。

下面是我的代码：（索引和伪造查看器）

是的，您缺少按钮的 CSS 以及对与 HTML 文件中的扩展相关的 JS 文件的引用。

<script src="your_folder/MyExtensionFileName.js"></script>

http://learnforge.autodesk.io/#/viewer/extensions/selection?id=toolbar-css 检查此扩展按钮的 CSS。
