Forge Viewer无法显示边缘 [英] Forge Viewer fails to display edges

问题描述

我使用了 https://github.com/Autodesk-Forge/viewer -react-express-headless 作为我的Forge React应用程序的起点，我将viewer = new Autodesk.Viewing.Viewer3D(viewerElement, {});修改为viewer = new Autodesk.Viewing.Private.GuiViewer3D(viewerElement, {});，以将其从无头更改为经典查看器.

I used https://github.com/Autodesk-Forge/viewer-react-express-headless as a starting point for my Forge React application and I modified viewer = new Autodesk.Viewing.Viewer3D(viewerElement, {}); to viewer = new Autodesk.Viewing.Private.GuiViewer3D(viewerElement, {}); to change it back from a headless to a classic viewer.

我可以加载我的模型，但是它看起来没有边缘，当我进入Settings -> Performance -> Display edges时，默认情况下它处于关闭状态，当我尝试将其设置回去时，边缘保持不可见.

I can load my model but it appears without edges and when I go to Settings -> Performance -> Display edges it is off by default, and when I try to set it back the edges stay invisible.

从我无法唤醒的查看器中:

From my non wokring viewer:

当我尝试对加载在 Autodesk Viewer 上的相同模型进行的相同操作时，它可以按预期运行，因此我可以切换边缘的可见性.

When I try the same operation with the same model loaded on Autodesk Viewer it works as expected and I can toggle the visibility of the edges.

从 Autodesk Viewer

我发现了另一个似乎相关问题，但是我尝试了viewer.js?v=v4.2，viewer.js?v=v5.0和viewer.js?v=v6.3.1，但仍然存在看不见的边缘问题.

I found another seemingly related question on stackoverflow, but I tried viewer.js?v=v4.2, viewer.js?v=v5.0 and viewer.js?v=v6.3.1 and I still have the invisible edges issue.

我还发布了 Github问题

谢谢您的帮助.

推荐答案

好，如果要通过创建浏览器实例 直接使用Autodesk.Viewing.Private.GuiViewer3D，而不是 Autodesk.Viewing.ViewingApplication，然后在初始化Forge查看器时需要应用一个魔术配置参数，以便这些行出现...

ok, if you are creating the viewer instance via Autodesk.Viewing.Private.GuiViewer3D directly, rather than the Autodesk.Viewing.ViewingApplication, then there is a magic configuration parameter that you will need to apply when initializing the Forge viewer, so that the lines will appear...

要解决此问题，一个额外的选择 isAEC: true必须传递到 您代码中的modelOptions，请参见下文:

To fix it, an extra option isAEC: true must be passed into the modelOptions in your code, see below:

var modelOptions = {
    placementTransform: mat,
    globalOffset:{x:0,y:0,z:0},
    sharedPropertyDbPath: doc.getPropertyDbPath(),
    isAEC: true //!<<< Here is the missing line
};

viewer.loadModel(svfUrl, modelOptions, onLoadModelSuccess, onLoadModelError);
