Strangely, there ARE already a number of default components which do ressemble these general shapes (Circle ring, being just one of many)... but as they say, one can always ask others to do it **or** actually take a crack at that particular task for themselves; meaning, i'm waaaaaaayyyyyyy too busy with X-Worlds ships right now to even fathom about tackling other projects - not everyone is as efficient & smart with design than AFRonin (just take a look at all his Star Trek Fed&Emp fleets and you'll understand how complex & tedious making a few ships can get.
I've learned a lot from him just by analyzing the trick_of_the_trade devices he used up, extension pylons, etc. Even the KSHMod hardpoint offsets gives anyone frickin' huge leeway to modify any default structures to fit a different angle, size or shape.
All it takes, is patience, good knowledge of what's available and a bunch of mod files - from others and if not, your precious time! The coolest stuff is sometimes the result of a personal drive to create.
Funny though, that one of the CoSH mod Minors is the Vulcans and i used a D'kyr class image as a Trading screen.
