The Design Process

Because Prometheus is a smaller build than the typical scale I build at, it was both an easier and more challenging build. It was easier in that it was much quicker to design and structural stability was less of an issue. However details are always much more difficult at a smaller scale!

The process of designing this build was to start at the front and work my way through to the back, and then build the top section. This was fairly straightforward with the exception of “greebling” (elements that look like they have a purpose but don’t). The greebling ran along the side to add extra details.

The most challenging aspect of this section was the front. The angles are exceptionally complicated with lots of different sections. It was actually much more challenging than the Daedalus so the biggest hurdle and the most rebuilds happened at the very start! Once this was done the rest of the build was fairly fast.

The only other difficult section was the engines. The scale made it difficult to design an engine from scratch so I needed to find an element that matched the shape. This wasn’t too challenging but finding an element that matched the size and shape was a bigger task! In the end I combined a few elements, though I am still not completely pleased with the result.
