Oh, I see, I can build my orb-hab in my factories. Thanks a lot. I will follow Icecoons advice anyway, my ships tend to become quite big, perhaps a noob problem?
But the information about sector commands may not be so welcome, for this means, if I understand it right, that I will have to build the sector command on a planet, because it is not possible to have orbital factories in space, right? I have seen that almost all other planet-bound activities can be duplicated in some space versions, but not the factories. Sector bonuses are quite good I believe, but having to terraform a crappy planet with no minerals, or haul a lot of infrastructure there, and factories, just to get one, well, he better be a very good governor, then.
