Materials
The same calculations. The same design standards. The same verified results — at a fraction of the cost. Every engineer deserves access to professional steel design software.
Expensive licenses
$3,000–$15,000/year for a single seat. The same formulas, the same standards — just locked behind a paywall.
Workarounds and compromises
When software is inaccessible, engineers find alternatives. Outdated versions. Unofficial sources. No updates, no security, no support.
Locked to a desktop
Install on one machine, tied to one OS. Work from a different computer? Start over.
Weeks to learn
Traditional software requires extensive training before you can be productive.
Start free, scale affordably
Full 3D editor at $0. Pro features from $9/mo. That's less than what the giants charge per day.
100% legitimate, always current
Regular updates, full support, clean licensing. Engineering deserves proper tools.
