Understand how to make EXTREMELY large objects if i should? So intend to make a space colony ship for a VR game I'm messing around with and I'm wondering if i should even be doing it this way.

The ships length measurement is going to be 18000 meters obvious this is massive I'm not too experienced in Blender but i found how to increase the size of the grid.

Unfortunately no matter what I try 18000 goes far beyond it and when i try to zoom out the screen goes weird.

What is the correct way of doing this or is Blender not the right place to do something this large.

I have seen videos on youtube comparing sizes of ships but i cant figure out how you can see everything in that
After comments and talking to people I realized that i shouldnt actually make something that large. when im making a scene just make it look larger than it is and when its in game make it so they dont realize isnt completely made
