The result (pass/fail and utilisation) is free to use with no account. Signed in with a free account, you get 3 full designs a month. The calculator packs (on sale soon) unlock calc sheets, bending schedules, drawing sheets, saved work and the project board. The calculators help you check a design; every design must still be checked and signed by a registered professional engineer.
