Can't find hole feature for terrain?

• Added holes feature: you can cut holes into the terrain now and drive below terrain as well.
• widened the editor sidebar from 210 to 260 pixels
• improved the starting height of the sidebars to fill the whole screen all the time
• Do not allow the headlights to be selected when selecting vehicles
• Removed a lot of obsolete sound classes

I can't seem to find this options, I don't know if it's a bug or what, if you have it could you show me a screenshot.

 

That was there before, I mean you can make terrain over hangs show in one of the images.

 

yes but thats how its done, you make a hole, then you stick a mesh under it i think
