Everything for the engineer who'd rather write the macro.

A small shop for Tekla Structures: a proper course on the Open API, free macros that each do one thing well, and a museum of engineering software from before the machines started writing it. In the back, past the bolt bins, there are some games.

Aisle 01 — sample stockTekla.Structures.Model

// Six metres of S355, from nothing.
var model = new Model();
if (!model.GetConnectionStatus()) return;

var beam = new Beam
{
    StartPoint = new Point(0, 0, 0),
    EndPoint   = new Point(6000, 0, 0),
    Profile    = { ProfileString  = "UB305*165*40" },
    Material   = { MaterialString = "S355JR" },
    Class      = "3",
};

beam.Insert();
model.CommitChanges();

Why a superstore

The one person in the office who knows how the API works is about to retire.

Tekla Structures is thirty-odd years old and still holding up a good deal of the steel you walk past on the way to work. Its Open API is genuinely powerful, thinly documented, and learned almost entirely by leaning over someone's desk and asking.

Meanwhile everyone is pointing AI at the problem and discovering that the model has never seen a real bolt schedule either. So this is the plan: write it down properly, while writing it down is still worth doing — and keep the toolbars, the modal dialogs and the .db1 files on display while we're at it.

Tekla Open API — the course

From new Model() to a plugin your team will actually install. C#, real fabrication models, no toy examples.

In fit-out

Macros & snippets

Small, free, copy-paste. Renumber assemblies, audit profiles, dump a bolt schedule straight to CSV.

Stocktaking

The back room — games

Local splitscreen, gamepad-first, built for two people on one sofa. Made in Godot.

In development

The museum

Field notes on engineering software as it was before AI — the toolbars, the dialogs, the file formats, the people who knew them.
