How to level (smooth) landscape's surface?

Hi.

I working on build mode in my game and I need to level (smooth) landscape’s surface.

For example, landscape:

I need to level (smooth) landscape’s surface in the form of a square two-dimensional by clicking in game on some position in the landscape. I think, that clicked coords will be center of the two-dimensional square and landscape’s surface in the needed area must be leveled. It’s needed, for example, to level surface of the landscape for placing the foundation of the house.

How to level surface of the needed area of the landscape by coordinates in blueprints or in C++?

Thank you!

If you are looking to make a flat surface by editing the Landscape in runtime, c++ is the only way I have heard.

My solution would be, place a mesh at the highest point the size you want. Use a box trace.
