I want to write a detailed description of ship building. I want to have a section in my story where the engineers might have to fix or repair parts of the spaceship if it comes under attack. My question then is how do you describe something that doesn't exists? My only answer that I've been able to come up with is: to make it up, correct? In other words I would go about by first building a parts glossary if you will with a description on what each part does. I would have to build a sci-fi starship language just as much if I were to come up with a new speaking language for a non-human race, correct? I'm assuming it would be in sections like are computers are now. For example if our video card goes out on our computers, we don't sit and troubleshoot to the component level, at least most of us don't. We go to best buy and buy a new one and pull the old one out and plug it in and now it works. So I'm thinking more core component level, but deeper than just saying the "main warp drive." Thanks.
