Check the member. Print the calc sheet. Schedule the bars.
STATIX is design software for structural engineers and detailers. 32 calculators run in your browser: each one draws the element, checks it clause by clause and gives you the calc sheet and the SANS 282 bending schedule. STATIX 2D draws the bars in AutoCAD.
Free account: every check with its clause, the full calc sheet and the bending schedule for 3 designs a month. Email or Google, no card. The pass or fail result needs no account.
In development STATIX 3D: the whole building in one model, with RC design, connections and a Revit link. Every feature and its status →
Start with a check you already know.
Single-purpose calculators to SANS, Eurocode and BS 8110, in your browser with no install. Each one draws the element and gives the result. On a phone they open as Inputs, Results and Calc sheet tabs.
Reinforcement drawings, in the CAD you already use.
An AutoCAD add-in for reinforcement detailing: bars drawn as real SANS 282 shapes, labelled and scheduled from the same data, so the drawing and the bending schedule cannot disagree. Wizards for beams, columns, bases, pile caps, strip footings, slabs, stairs, retaining walls, shear walls and house foundations.
Download STATIX 2D Read the tutorial
Free for 30 days with the trial (one per account and one per PC, no card), for AutoCAD 2025 and 2026 on 64-bit Windows. Drawn by the add-in in AutoCAD 2026, plotted, no hand edits. Example values, not a designed job.
From the calculators to the drawing set.
The project board collects the elements you design in the calculators into one project: drawing sheets, schedules and quantities, with the loads passed from one element to the next. STATIX CAD opens and edits the drawings in your browser. A free account holds one project with 5 elements; the 30-day trial opens the rest.
Project board
- Elements on drawing sheets, with one SANS 282 bending schedule
- Column, footing, beam and lintel schedules, and a setting-out plan
- A quantities table: concrete m³, formwork m² and steel kg
- Columns, pads, walls and grids found in the architect's DXF plan become elements
- Loads flow down from beams to columns to footings, and from walls to strip footings
STATIX CAD
- Start a drawing on A1 or A3 at a scale, or from your own template with your title block and layers
- Open any ASCII DXF: lines, arcs, text, blocks and layers
- Edit, save as DXF for any CAD program, and print to scale
- Free with an account: open a DXF to look and measure
Learn the design behind every check.
12 online courses with 80 lessons, each lesson tied to a calculator. The theory is open to everyone. The worked examples, exercises and quiz open with a university or college email or a student licence. For universities and colleges →
Also free to read: 29 worked examples, each solved by hand and in the matching calculator, and 33 calculator guides.
What you can use today, and what is being built.
Every feature, with an honest status. Live means you can use it on this site or in STATIX 2D today. In development means it is being built and tested, and is not on sale yet.

Every check with its clause, the full calc sheet and the SANS 282 bending schedule: 3 designs a month. Email or Google, no card.
One model, from analysis to the site.
Build the structure once. STATIX 3D solves it, designs every member, slab and connection clause by clause, and hands the result on as calc sheets, bending schedules, STATIX 2D drawings and models for Revit and Advance Steel. In development: one click to design a whole concrete or steel building.
Beams, columns, footings, walls and slabs, designed with the forces they really carry.
Every joint in the frame, found for you, then checked in 3D.
Model in, changes listed, bars back as native Revit rebar.
In development. STATIX 3D is not open to the public and not on sale yet. The pictures come from the current development build, solved under self-weight, finishes and imposed load. Full member and connection design, and wind, crane and seismic cases, are still being built. See one portal frame, joint by joint →
