    How it works

    From a rough idea to a brief an engineer can sign off

    Three steps, the same in every tool.

    1

    Choose your tool

    Groundwork for buildings, houses and sites. AeroSim for anything that flies or races. HydroForge for pipes, tanks, channels and hulls.

    2

    Run the checks

    Enter the real site or design and get the numbers straight away, with the working behind each figure so you can see where it came from.

    3

    Hand off a clean brief

    Print, download or share a report that lists what is settled and what is still open, for the professional who signs it off.

    See what you get

    Reports you can read, check and hand over
