What is this? Considering the scale of dalmonts station, it could be easily recreated in a day or so. Especially so if there's some reference material to look at. We also don't know how long dalmont worked on it beforehand. As to whether it is an "original" design, it doesn't matter. I haven't seen that starbase picture in my life. The only thing that looks similar are some starbases from star trek. That's once source out of all the sci-fi I have seen. Just because you have seen it before, or built something similar doesn't mean its not original. The dome and paneling on the bottom don't even look like the one in the picture. The only similarity is the general shape.
As for phoenix, it still looks like a quick rebuild of dalmonts design. Dalmont posted his current build on this thread, and later phoenix posted their station for download. All of the key features are there. ALL of them, Panels on the bottom, the hanger design, the ring and the dome. The odds of two people coming up with that design in so short a time... How can we even question that?
If someone came to this thread and posted a brown octangular station with lots of support beams and glass entryway, I would be pretty pissed. That would be, at that point, unoriginal, because I already posted my build to this thread. Dalmont has every right to be mad.
