There will be many layer to the simulation from gas and liquids to heat and pressure. Today we will look a bit into the system used to move gas and liquid around.
Overview of pipes and their accessories:

Diverse way cooling system will be possible, we will look at the bulk of heat simulation another day:

The beginning of an atmospheric system:
looks nice - its very useful features so its will be able to do muilt levels like pipes between two levels and such?
The multiple Z-Level are not in yet, but it is something i will add at some point. I was thinking of maybe a color coded way to add multiple pipe networks, not exactly sure how this will turn out yet.
cool that's sounds exciting - elevators and power systems and such would be great
