How to build Sub Assemblies?

[Richter]

Hi, I tried to look this up on the forum, since I assume that this is a common issue for everyone that keeps on playing KSP, but didn't found anything.

My question is: If I understood the game's lingo correctly it is possible to build certain modules (like a rover, a probe or even a full launcher) and to load them while building a new design. This is the concept of sub-assemblies, am I correct?

So, how does one saves something as a sub-assembly? I've looked all over the place, I can find the "Load Sub-assembly button" but not any option to save as a sub-assembly...

I have a ton of lauchers, rovers and probes, plus some new projects that would be perfect for the part that I wanted to use that way. Can anyone help?

It's not doable in the stock version. You need a mod for it. Try here: http://kerbalspaceprogram.com/subassembly-manager/

That's in the next version -- 0.22.

That's in the next version -- 0.22.

We hope!!!

It sounds like you already have the Subassembly Manager mod installed, from the description.

What you need to do: Pick up the subassembly you wish to save as if you were going to move it somewhere else. The "Load Subassembly" button should change to a "Save Subassembly" one while those parts are selected. Just click on that button to save those parts as a new subassembly.

Important note: you can't save it if you got the root part selected. first place the root part, then build the subassembly on it. you can only attach a loaded subassembly by the node that you detached it from.

semi-off-topic note: if you're using an RCS balancer tool, create a pod with "mass = 0", then you don't have to worry about that when balancing the RCS for your subassembly.
