For structural engineering teams

Structural models your whole team can work on.

Bring engineers, scripts and AI agents together on a single model. Explore design options, review every change and run code checks in one place.

3D Viewer Review Agent Python API REST API

A production hall in the Tron 3D viewer, with the bending moments of a load case drawn on its frames

The production hall in the 3D viewer against main: 14 changed rafters in orange and 8 new roof braces in blue

Rafters IPE 360, roof bracing

8 added 14 changed IPE400 → IPE360

AI agent

Try IPE 360 for the rafters on a new branch, run the analysis and tell me what changes.

I created the branch lighter-roof and changed 14 rafters to IPE 360. The analysis has finished: the largest bending moment is 97 kN·m.

Good. Open a merge request so Ben can review it.

Done: merge request #12, Rafters IPE 360. Ben can compare the changes in the 3D viewer.

Your entire model, in one place

Replace scattered files and calculation sheets with a single shared project for your whole team.

Branches

Explore design options side by side. The main model stays untouched until you decide to merge.

History

See who changed what and when, down to a single member, and return to any earlier state.

Reviews

Propose changes for review. Colleagues inspect them in 3D, comment and approve.

Code checks

Check your design against SIA 260 and SIA 263 at any stage of the model.

Optimisation

Let the optimiser propose cross-sections, then review them like any other change.

Automation

Automate your work with the Python SDK or REST API, and export a project with its full history at any time.

From first idea to final submission

The workflow of modern software teams, adapted for structural engineering.

Branch

Start a variant without touching the main model.

Change

Edit the model yourself, by script or with an AI agent.

Review

Compare versions in 3D, review the checks and discuss them in the browser.

Merge

Bring the result into the main model and tag it for submission.
