We're structural engineers who build software — not the other way around.
Strux Labs is a structural engineering firm that designs residential and light-commercial structures. For years, we used the same workflow as everyone else: import plans into one program, run calcs in a spreadsheet, cross-reference reactions by hand, and cobble together a submittal package from three different tools.
We kept saying, "Someone should build a tool that just lets you draw the structure on the plans and does the calcs right there." Eventually we realized that someone was going to have to be us.
StruxDraft is the result — a purpose-built desktop application that combines structural drafting and code-compliant design in one place. We didn't build it to sell a product; we built it because we needed it. Every feature in StruxDraft exists because we hit a real problem in our own practice and wrote the solution.
To close the gap between structural drafting and structural design — so engineers can spend their time engineering, not managing files.
Every calculation is traceable to a published standard — NDS 2018, ACI 318-19, ASCE 7-22. No black boxes. No hidden assumptions. You can see every variable, every adjustment factor, every load combination.
StruxDraft is fast because it's built with modern technology (Rust + React), not because it skips steps. You get full code checks in real time — not simplified approximations.
We use StruxDraft every day on real projects. When something doesn't work well, we feel it immediately — and fix it. Our roadmap is driven by actual engineering workflows, not feature checklists.
The engineers behind the engineering tools.
Licensed PE with deep experience in wood-frame residential and light-commercial structures. Leads the structural analysis engine development and ensures every calculation is code-traceable.
Licensed PE focused on production engineering and plan review efficiency. Drives the drafting workflow, UI design, and the practical day-to-day usability of every tool in the suite.
"We got tired of opening a beam in a spreadsheet, typing in the span, typing in the loads we just calculated two minutes ago, then copying the result back into our plans. If the loads changed, we'd have to do it all over again. There had to be a better way."
The fundamental problem is that structural drafting and structural design have always been separate. You draw in one place and calculate in another. Reactions don't flow automatically. When something changes, you update manually everywhere. Mistakes hide in the gaps between tools.
StruxDraft eliminates those gaps. When you place a beam on the plan, it already knows its span. When you connect joists to that beam, the tributary loads calculate automatically. When you change a joist spacing, the beam recalculates in real time. The engineering stays connected to the drawing — because that's how it should work.
