i think it be a smart idea to add in bulkheads for sections open to space.

I was in architecture field and i switch to game industry lately. find sketchup is underrated , and i believe sketchup probably more fast modeling tools for architecture blockout or gray box phase

Maybe someone suggested it already bit maybe deck/overhead instead of floor/ceiling? Having another F in the panel code could be confusing with F for Forward quadrant. Just a thought

I like the idea for wall panel replacements: Like a self fabricating wall panel. It might also make sense to make it a little more futuristic/techy and make have a material cost per panel section (Calculated by some dimensions already available on the wall section). When a player wants to remove a section of wall, they reclaim the panel into a condensate matrix (a tool which would have aa physical container for the material of the wall) and when the repair is finished they replace the material from the matrix into the section. It might require you to have a physical representation of the object, but I'm not a game developer. In theory, you could have one object that contains all the material required for your wall (maybe per deck), and each wall panel draws off that material container to determine what to display and what state it is in. (Damaged wall composite material may give the actual panel a degraded visual state, necessitating replacement to restore to desired look and function). Anyway, I paused the video to write all this so maybe you've already come up with something cooler or more efficient. Keep up the great work!

Absolutely amazing what has been achieved so far, but this ship design is the wrong approach.
