Wood buildings, designed and drawn.
AREZ designs the wood structure to NDS 2024, SDPWS 2021 and ASCE 7-22, then draws the structural sheets from the same model. A Windows app that runs offline.
Regular price $129 a month. The pre-order price stays for as long as you keep your plan.

Six steps, one model.
The bar at the top of the Building page holds the whole job. Each step runs only when you press it, and its dot tells you where the project stands.
- 1
Model
Levels, walls, openings, roof and floor framing. Start from scratch, a DXF plan or the sample house.
- 2
Wind
ASCE 7-22 wind for the model as it stands, worked out wing by wing on irregular plans.
- 3
Analyze
Applies the area, plan and wind loads and runs the load transfer until every member load settles.
- 4
Design
Checks every member against the current analysis. Size failing members is one click.
- 5
Sheets
Opens the drawing set once every member passes, or as PRELIMINARY if you choose to look early.
- 6
Export
The PDF set, DXF and DWG files, and a package for Revit.

What it designs, and to which code.
The wood structure, member by member, and the connectors that hold it together. Every connector value is cited to its catalog page.
| Member | Checked to |
|---|---|
| Joists, beams and headers | NDS 2024 |
| Posts and stud walls | NDS 2024 |
| Shear walls and diaphragms | SDPWS 2021 |
| Wind loads and load combinations | ASCE 7-22 |
| Holdowns, straps, hangers, post bases, hurricane ties | Simpson Strong-Tie C-C-2026Model, allowable load and catalog page on every pick. |
| Sill anchor bolts | NDS 12.3, ACI 318-19Spacing from the shear wall unit shear. |
| Trusses | Preliminary sizing checks. The truss manufacturer designs and certifies them. |
| Foundations | Not designed. AREZ gives the loads at the base of the wood structure to the foundation engineer. |
NOT VERIFIED shows on any result until the code and product data it uses are signed off on the Verification page.
The sheets come from the model.
General notes, framing plans, the building section, wall sections, details and schedules, in the S-600 series with the AREZ title block and a sheet index. Each new generation lists what changed since the last one.
- Nothing invented.A value that is not in the model is drawn as a flagged assumption or a red engineering-review note.
- Failed details are not drawn.They go to the Unresolved Design Items list with the problem, the reference and the fix.
- PRELIMINARY until sealed.Sheets say PRELIMINARY, or NOT FOR ISSUE while items are open, until the engineer of record reviews and seals them.

- DXF, AutoCAD 2013 layers

Ask Mijo.
Mijo is the assistant inside AREZ. Ask about the project, have it review the sheets, or tell it what to change in plain words: members, walls, openings, levels, roof and loads.
- On your computer.Its AI engine is an open model that runs locally through Ollama, about 6 GB. A graphics card helps.
- You approve every change.Mijo shows the change first and saves it only when you press Apply.
- It learns your references.Drop PDFs, notes and tables into its Library and it answers from them.
- It says what it cannot do.Masonry walls or rotating the building, for example, get a plain answer and the reason.
- Which members fail on level 2, and by how much?
- Make a node at every wall intersection.
- Make these walls bearing shear walls.
- Review the sheets before I send them.
- Ctrl+/ opens Mijo on any page.
Your projects stay on your computer.
AREZ needs no account and sends nothing anywhere. The one exception is the optional Real site view, which sends the site location and your own Google Maps key to Google.
- System
- Windows 10 or 11, with Microsoft Edge or Google Chrome
- Units
- US imperial or metric SI, across the whole app
- Mijo's engine
- About 6 GB, set up by the installer
- Backups
- One file holds every project, from About & legal

Questions.
Does AREZ replace the engineer of record?
No. AREZ is a design aid for licensed design professionals: structural and civil engineers, and architects where the jurisdiction allows. You check every input and result, and drawings are not construction documents until the engineer of record reviews and seals them.
Does it design foundations?
No. AREZ designs the wood structure and gives the loads at its base, so the foundation engineer can design the footings.
Which code editions does it use?
NDS 2024, SDPWS 2021 and ASCE 7-22, with Simpson Strong-Tie C-C-2026 for connectors. Confirm they are the editions your jurisdiction has adopted for the project.
Does it run on a Mac?
No. AREZ runs on Windows 10 and 11.
Does it need the internet?
No. It runs offline and keeps your projects on your computer. Only the optional Real site view goes online.
How do I cancel?
Email nizar@taktek.io. Your plan stops at the end of the period you paid for.
Is AREZ part of Simpson Strong-Tie?
No. AREZ is not affiliated with or endorsed by Simpson Strong-Tie or any other manufacturer. Their published data is cited by catalog and page; confirm it against their current literature.
