推荐答案

在处理 really 大型模型时，需要考虑以下两个选项:

Here's a couple of options to consider when dealing with really large models:

1. 使用 Autodesk.MemoryLimited 查看器扩展来控制为模型分配的内存量(以避免浏览器崩溃或上下文丢失):

1. Use the Autodesk.MemoryLimited viewer extension to control the amount of memory allocated for the model (to avoid browser crashes or context losses): https://forge.autodesk.com/en/docs/viewer/v7/developers_guide/viewer_basics/memory-limit.

使用新的 SVF2 文件格式，可以检测并删除许多重复的几何图形，从而减少了必须从服务器下载并发送到GPU的几何图形总数.

Use the new SVF2 file format which can detect and remove many duplicate geometries, decreasing the total amount of geometry that must downloaded from the servers and sent to the GPU.

作为最后的选择-我们的客户也这样做-尝试将Navisworks设计分成多个模型(例如，按区域或学科划分)，然后按需加载.

As a last resort - something our customers also do - try splitting the Navisworks design into multiple models, for example by area or discipline, and then load it on demand.
