How do you recenter/undo in building?

[Synergy25]

There have been times where I didn't like what I did while building and want to revert/undo my last part added or repositioned. How do I do that? Also if I grab my rocket and move it off center, how do I recenter it? Thanks to all that help.

You can undo with control+Z or command+z. After clicking on it, drop it on the side without deleting it. I really don't know how to recenter.

I find the best way to move the rocket in the VAB is with the offset gizmo. By clicking the root part - the first one you selected - you can move the whole rocket. Turning on angle snap means you can get it exactly centred.

Shift-clicking on any part will select the whole craft, even with offset and rotate gizmos. The "circle" with the vectors to drag will still be centred on the root part though.

When you snap a part onto your ship, its position/orientation at that moment is the "default" position/orientation for that part.

When you edit the position/orientation of said part, you can return to default position/orientation by choosing the appropriate editing mode then pressing the Space key.

You can center the root part by using the offset tool with snapping on, then just drag it to the center.

Thanks all for the input. I'm new to this Amazing game. I'm sure I'll have more questions to come.
