Hi, I have started to make a small console program that read/analyse EPB files. It can also generate EPB files with some basic shapes. The purpose of this is to map out the file format and enable more complete tools for generating content with correct block types, colours, textures, symbols all the way up to functioning signal logic. The program is written i C# .Net and works with mono for non-Windows users. The project can be found here: https://github.com/ApanLoon/EmpyrionStuff I attach an example output for a ship I just made.
