WorldEdit - How do I change the topsoil block?

[Peter Romanov]

I'm slowly getting the hang of WorldEdit, and it's been interesting to work with this tool, but along the way, a question has arisen.
I've built a fairly complex landscape out of dirt blocks, and now I'm a bit stumped, as I need to somehow replace all the topsoil blocks to ensure they blend seamlessly with the surrounding terrain. Manually replacing each block would be incredibly time-consuming, and I'd really like to avoid that.
So, I'm wondering if there's a way to do this more or less automatically, using existing editor tools or console commands.

I am not a WorldEdit pro by any means but, depending on how exactly your landscape looks and what you want to achieve there, I'd start wiith either the Pain Brush Tool (particularly with a focus on Depth Layer, starting at around 10:30) or the Air Brush Tool.

I recommend you to watch the whole video. Maybe you find techniques more suitable to what you want to achieve.

Я ни в коем случае не профессионал WorldEdit, но, в зависимости от того, как именно выглядит ваш ландшафт и чего вы хотите добиться, я бы начал либо с инструмента «Кисть для рисования»  (особенно с акцентом на слой глубины, начиная примерно с 10:30), либо с инструмента «Аэрограф» .

Рекомендую посмотреть видео целиком. Возможно, вы найдете там методы, которые лучше подойдут для достижения желаемого результата.

Honestly, it doesn't seem like the tools mentioned above will help me. The thing is, they're installing new blocks, but I need to replace some of the old ones with new ones...
For example, in my situation, replace blocks without grass with blocks with grass.
