And this is called Nudge Mode.

So what Nudge Mode is, is first of all, it's two things.

It's the ability to lock a hologram in place.

You can now press H to lock your blueprint hologram in place, and then you can walk around it and you can check, is this position correctly or not?

right before building.

And if you're happy with it, you click again and then it builds.

So when in nudge mode, blueprint building becomes a two-click process.

But if not in nudge mode, it's just the normal one-click process.

So nothing changes in the default case.
