a pit on the ground

[zhangle]

I am editing a model built by others. As shown on pic 1, there is a pit on the ground beneath the main entrance, which should not be there. I guess there must be a bad point in the topology. But when I try to modify the topology, there is no point there. And I dont know what to do now... Help me please. Thanks!

Check your view range. Also, use wireframe view.

It's the view range! Now I can see and delete the point and everything is fine! Thank you so much!
