Create a helper point in a selected vertex?

#1

I need someone to be able to help me with the following.
How to create a helper point in a selected vertex of a mesh geometry.
I think it’s simple but I don’t know how to solve it. I’m a rookie.

#2

One simple way of doing it, while avoiding working with different objects classes, transforms and modifier stack would be to snapshot the node and get the selected vertices. It isn’t perfect but should work in most cases.

(
	tmesh = snapshotasmesh selection[1]
	sel = getvertselection tmesh
	
	for j in sel do point pos:(getvert tmesh j) wirecolor:green
)

That’s exactly what I was looking for, it works like a charm, thank you very much.
