A desktop suite built by structural engineers, for structural engineers. Draft directly on your PDF plans, run code-compliant calculations in real time, and visualize the whole structure in 3D — all without leaving the application.
StruxDraftStruxCalcStrux4DOne suite, three windows on the same project
Watch StruxDraft go from PDF plans to a checked, connected structural model.
StruxDraft, StruxCalc, and Strux4D share a single calculation engine and project format — so design, verification, and visualization stay in lockstep.
Draft structural elements directly on top of your PDF plan sheets. Real-time NDS, AISC, and ACI code checks. Connected load flow from roof to foundation. Live schedules and one-click calc reports.
Fast member sizing and field checks. Same calc engine as StruxDraft, no project file required.
Read-only 3D viewer. Trace load paths, share with clients and contractors, no install required. Try it free in your browser.
Inline-editable beam, joist, column, wall, and footing schedules with real-time utilization badges.
Every check shows the governing equation, code reference, and substituted values. No black boxes.
Every feature exists because we hit the problem on a real project.
NDS 2018, AISC 360, ACI 318-19, ASCE 7-22, IBC 2021 — built in, kept current.
Native desktop performance via Tauri + Rust. Launches in under a second, edits feel instant.
Joists feed beams, beams feed columns, columns feed footings — automatically, every time.
One-click PDF calc package with title block, design criteria, member checks, and reactions.
15 database tables for materials, grades, sections, connectors, and load combinations. Override anything.
We use the suite every day on real projects. Feedback loop is one team, one product.
A few of the workflows that make the day-to-day faster.
Import PDF construction documents and overlay every structural element on the sheet. Side-by-side view keeps the original plan visible while you design.
Open any member to see the governing checks, the equation behind them, and the code reference. No black boxes — every value is traceable.
Strux4D builds a 3D model from your 2D plans automatically. Click any member to inspect properties and connections. Catch missing load paths before they reach the field.
Dedicated designers for retaining walls, base plates, columns, and beams — each with code-compliant checks and clear pass/fail utilization.
Public beta opens June 2026 with founders pricing locked in for early adopters. Production release Q3 2026.
