You can regenerate the world after building your blueprint library. The regenerated world will use your designs to populate your faction's territory.

oh cool
how many ships do you need for it? just any amount above 0?

A small disclaimer, it's been a long time since I did this. Nonetheless I recommend a couple of ship designs plus at least one station design in your blueprint library.

Your ship designs should span a range of manufacturing costs. I'd personally make a few big designs within 1,000 P ~ 2,500 P, and more smaller designs between 200 ~ 600 P. I wouldn't have a specific budget my station design, I'd build one or two really cool ones! Don't forget R storage and factories for your stations!

I emphasize: there are no hard rules for this.

For context:

The game populates the campaign map with "regions", areas with roughly defined characteristics. The game populates each region with its own fleet of ships based on two important parameters:

> Range for fleet budget
> Range for number of ships in fleet

Based on my personal observation - the game will use your own ship designs to satisfy the fleet size and budget requirements as best it can. If the game can't populate a region while satisfying these two requirements using only your ships, it will start to use vanilla designs. That's not what we want. :(

A varied blueprint library provides the game with enough fleet composition flexibility to ignore vanilla designs.

I hope this helps!
