JointLIB · v0.0 · 2026

Automation for structural engineering.
Analysis, modelling
and drafting.

Eurocode design tools and AutoCAD, Tekla and Revit automation, built to cut working time, take over repetitive tasks and reduce the errors that come with structural design.

// 01 — WHY JOINTLIB

Put AI to work in analysis, modelling and drafting.

Removes the uncertainty of using AI in design — a consequence of how non-deterministic it is — along with the need to write long prompts, which are often easier to implement than to write, and even then may not produce what you wanted.

01 / NON-DETERMINISTIC PROCESSES
PROMPT POSSIBLEOUTCOME 1 POSSIBLEOUTCOME 2 POSSIBLEOUTCOME 3 POSSIBLEOUTCOME 4 POSSIBLEOUTCOME 5

Non-deterministic processes

AI is a non-deterministic process in itself: for the same input it can produce different outputs depending on when you ask. Mathematical processes are the opposite — deterministic, one input, one output.

02 / FORM GENERATION
M = kNm
W = cm³
σ = … N/mm²

Generating analysis, modelling and drafting

To fit into the design process, the output produced by artificial intelligence has to be processed through code, using formulations and algorithms that guarantee a deterministic result.

03 / TEST AND VALIDATION
σAI = σTEST ?

Testing and validating forms

Once the analysis/modelling/drafting form is generated, it is a deterministic process: it will always produce the same results, ones you can rely on as an engineer.

// 03 — FORK SYSTEM

Fork it! Build your own tool starting from an existing one

Tools are reused through a fork system: any public tool, or set of tools, can be the starting point for a more complex one with more checks.

// 04 — THE JOINTLIB AGENT

An agent that connects to the software you use

The JointLib agent ships with a set of two-way bridges linking the site to the APIs of the most widely used software on the market today.

01 / ANALYSIS

SAP2000 integration

Send models and pull section forces through the OAPI — nodes, members, loads and results, straight from the site.

02 / MODELLING

Tekla integration

Extract nodes and connections from the model and send parametric components back through the Tekla Open API.

03 / MODELLING

Revit integration

A live bridge to Revit — create and update structural elements and families straight from the platform.

04 / DRAFTING

AutoCAD integration

Generate parametric .dxf drawings and details — formwork, reinforcement and dimensioning, ready to drop into your drawing.
