问题描述
我需要激活配置文件设置 forceDoubleSided 才能正确显示从具有镜像外部参考的 Revit 项目派生的模型.
I need to activate the profile setting forceDoubleSided in order to display properly a model derivated from a Revit project that has mirrored external references.
使用最新版本的 Forge Viewer，当我调用 new GuiViewer3D(container, config) 时，我在 config 参数中设置了配置文件设置，并且在加载模型时，材料属性 "边"= 2 (THREE.DoubleSide) 看起来不错.
Using the latest version of the Forge Viewer, I set the profile settings in the config parameter when I call new GuiViewer3D(container, config) and, while the model is loading, the materials property "side" = 2 (THREE.DoubleSide) and it looks good.
问题在于模型加载后或使用切割平面扩展后，因为材料侧"然后将其重置为 0 (THREE.FrontSide)，因此模型不再正确显示.
The problem is when the model has loaded, or after have used the cutting plane extension, because the materials "side" is then reset to 0 (THREE.FrontSide) so the model stops looking correctly.
作为一种解决方法，在 GEOMETRY_LOADED_EVENT 和 CUTPLANES_CHANGE_EVENT 事件中，我每次都执行 _viewer.impl.setDoubleSided(true, _viewer.model).
As a workaround, in the GEOMETRY_LOADED_EVENT and CUTPLANES_CHANGE_EVENT events I am executing _viewer.impl.setDoubleSided(true, _viewer.model) every time.
这似乎是查看器中的一个错误......有没有更好的方法来处理这个问题?
It seems like a bug in the viewer... is there a better approach to handle this problem?
推荐答案
这听起来像是一个错误.让我通知工程团队，感谢您的报告！现在，请继续手动覆盖边性"根据需要.
That does sound like a bug. Let me notify the engineering team, and thanks for reporting it! For now, please continue manually overriding the "sidedness" as needed.
