Replacing parts

[AntherJebediah]

Consider a spaceplane: You have been designing it, but you accidentally placed the wrong type of tank. To replace it, you have to remove the pieces and place them again. Is there an easier way to do this in KSP 1.2.2?

No sadly not i have tried this many times where i want to replace a tank with something else. My trick is for exampel to connect all the wing pices to one part so if you need to move the wings it is no pain. The same with engine clusters and so on

You can get one of the mods which allow you to change the contents of an already-installed fuel tank.

I do this a lot with stock spaceplanes due to needing different amounts of LFO and just LF. I normally work ut which bit has the most stuff attached to it. Press 4 to change the route part to the opposite side (it will require clicking on the part you want twice) and remove them all in the biggest chunk possible, especially for avoiding changing wing positions. change the tank and then re assemble. With to route changes you can normally isolate the right part.
