In any case, thanks! I understand what you meant by this toolkit, and as a result, your solution is very elegant. The surface point tools are a tricky process in places. And if you do one function, you will have to do another, and so on. And everything can grow into a tool that is difficult to understand.

But if we talk about selection tools. Is there any way to highlight a row/column of points on a surface? Or Grow/Shrink selection of points?
