That’s a very nice level you have there!
Depending on what you are asking, it might be a 5 minute thing for me to add what you are requesting
let me confirm
“While you keep pressing V, click on the desired vertex and move your mouse over a desired location.
While you move the mouse the mesh snaps to the vertex under it, release V and the mouse button when happy with the position.”
So you’re saying that
when you hold down V, you can then select vertices.
And once you’ve selected a vertex, while still holding V,
that vertex will now snap to the cursor position, and follow the cursor around the world?
What about Z axis?
Does the mesh stay on whatever Z level it was on, and follow cursor in XY plane only?
PS: a VIDEO by you would make this much easier for me
