我发现了另一个看似相关关于 stackoverflow 的问题，但我尝试了 viewer.js?v=v4.2、viewer.js?v=v5.0 和 viewer.js?v=v6.3.1 并且我仍然有不可见的边缘问题.

好的，如果您通过以下方式创建查看器实例Autodesk.Viewing.Private.GuiViewer3D 直接，而不是Autodesk.Viewing.ViewingApplication，然后有一个神奇的配置参数，你需要在初始化Forge查看器时应用，这样就会出现线条...

要修复它，一个额外的选项isAEC: true 必须传入代码中的模型选项，请参见下文:

var modelOptions = {放置变换:垫子，globalOffset:{x:0,y:0,z:0},sharedPropertyDbPath: doc.getPropertyDbPath(),isAEC: true//!<<<这是缺少的行};viewer.loadModel(svfUrl, modelOptions, onLoadModelSuccess, onLoadModelError);

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.

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.

From my non wokring viewer:

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.

From the Autodesk Viewer

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.

I also posted a Github Issue

Thank you for your help.

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...

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);
