So I built a rather complex rover and it has a robotic command pod so I can drive it from wherever it lands to where the Kerbals are. Now I want to build a rocket to get it there. For various reasons, the rover has to be launched nose-up on the top of the rocket and its pod, of course, is oriented for when the rover is flat on the ground. So, one of the 1st parts of the rocket was another robot pod oriented to fly the rocket. So far, so good.
HOWEVER, building the rocket is a total pain because the VAB is still basing the symmetry and all on the rover's pod, which is now tipped 90^ from the way it will be in use. Thus, every single part (including all struts, RCS blocks, fuel lines, Seprotrons, etc.) has to be placed individually because the symmetry mirroring puts all parts around a horizontal instead of a vertical axis.
So, is there a way to reset which pod the VAB uses for symmetry? If I could make it use the rocket's pod, life would be a lot easier.
FWIW, I have Subassembly Loader but it doesn't do me any good. It won't let you save anything with a command pod on it. I can remove everything but the pod and save that, and start building the rocket from its own pod so symmetry works, then add the rover subassembly to that. Problem then, however, is that because the rover was built around its pod, I can't get a replacement pod back inside the subassembly.
