What does red mean when building ship??

[Guest Darth]

so sometimes my parts for the ship are red after I place it, which I assume it means it doesn't work or something. Can someone clarify please...

It means the element is obstructed by something (other element, voxels). Example, if an engine is red, it means there is something behind it, and is obstructing it, making it less efficient.
