How to fix this issue in drive mode or realistic view

hello @afrazawan2010 

Create a new surface and insert first the existing surface and then the surface of your corridor.

In this way, the two surfaces will be subtracted from each other. In the end just show the new surface.

I hope it works 😉

The problem is that you cannot merge the corridor with a surface.
You must first create a surface from the corridor and then maerge it with the exisitng ground.
