The story behind the tools
Software with a
face behind it.
EngSurface is an independent studio building CAD, tolerance and simulation tools for working engineers. No venture money, no sales funnels, no jargon factory — just dependable instruments made by the people who once needed them at their own desks.

Our mission
Make engineering math boring,
reliable — and invisible.
Great engineering software shouldn't feel like a mountain of configuration files and license managers. It should feel like a torque wrench: pick it up, get the number right, put it down. That's exactly the bar every EngSurface product is held to.
We build the small, sharp instruments that CATIA, Fusion and NX users actually reach for: stack-up calculators, stack visualizers, export helpers, license generators — tools that turn a Wednesday of wrestling formulas into ten minutes of clicking the right button.
Remote-first and proudly independent — made in Morocco, shipping to engineers in 30+ countries. We answer to users, not to investors.
The EngSurface promise
- 14-day trials on professional tools — test before you pay, always.
- Every download includes its documentation and a working example — never a bare .exe.
- Receipts, license keys and downloads arrive within seconds of payment, 24/7, automatically.
- Honest limits written on every product page: what the tool does, what it needs, and what it deliberately does NOT do.
How we work
Four rules, no exceptions
Precision by default
Every tolerance tool ships with its math documented and its limits stated. Worst-case, RSS and Monte-Carlo — no black boxes, no hand-waving.
Real tools, zero fluff
Each product exists because it solved a real problem on a real engineer's workstation first. If we wouldn't use it ourselves, it doesn't ship.
You buy it, you keep it
Perpetual licenses, offline-friendly, instant delivery. Your license survives re-installs, new companies and our own bad days.
Fast, human support
The person who wrote the code answers the inbox. One email to support and you talk to the engineer — median reply under 24 hours.
The crew
Currently one human.
Built for more.
