它并非一个完整的游戏引擎，所以它不支持声音，网络或者高级的物理系统(但它对碰撞检测有一定程度的支持)，但我们可以使用扩展库来实现。
It is not a complete game engine, so it does not support sound, networking or advanced physics (but it has some support for collisions) and external libraries have to be used for that.
在所有国家中，超过四分之三的BIM使用者会用其做碰撞检测。
Clash detection is used by more than three quarters of BIM users in all countries.
性能分析也被广泛应用中，尽管它的使用量比三维可视化和碰撞检测都少。
Performance analysis is widely used, though less so than 3d visualisations and clash detection.
