@WangFuYuan199,

It looks like you posted essentially the same question in two different threads. Please see my reply in the other thread:

> [@为什么在调用报错呢meshData.addFaces is not a function](https://forum.techsoft3d.com/t/meshdata-addfaces-is-not-a-function/4740/5):

> @WangFuYuan199, So just to confirm, does the issue you are experiencing only happen when enabling the custom nav cube operator through a modelStructureReady callback? Are you able to use it without a callback? Thanks, Tino

Going forward, let’s just use one thread to correspond.

Thanks,  
Tino
