How do you copy stuff because alt click isn't working

[ColdOakMeal]

I have been told that you must hold alt and click to copy and paste something but this doesn't work for me whenever I hold alt I cant click anything so am I doing it wrong? i'm confused.

I think there might have been a change to that recently, because I had difficulty too when I first picked up the game after a long time not playing.

The easiest way I've found to copy one or more parts in vehicle assembly is like this:

1) Click the part of the rocket you want to copy, move it a little to the side so it's not connected to the rocket, click again to leave it hanging in space like a ghost.

2) Alt-click the ghost. Then you will have a copy of whatever part(s) you separated stuck to your mouse cursor, which you can put back where you got it or a different place, but you also still have the ghost assembly hanging in space where you can alt-click it again for more copies, or add it back to the ship.

Also make sure you're not trying to alt-click the root part of the vessel, that doesn't work.
