Hello Mugen
1. Adding ships. Yes, it looks likely we can but the method of doing so hasn't been explained yet.
2. Adding ports. Not disclosed, but I get the impression no.
There is nothing to stop you making a port in 3d though. Whether you will ever be able to upload it is not known. I'm making a couple of 3d items just for the hell of it.
One piece of advice, from someone who'se just starting in 3d. Make your first models not a port, but basic objects. Cubes, spheres etc. Play with them first.
Also, would recommend binning sketch. I'm trying blender- complicated but more detailed and usable.
