Structural calcs another engineer can check line by line
Loads, reactions, member forces and code checks in one worksheet: every given, equation and intermediate value visible, every unit checked, and the result traceable when a reviewer asks where a number came from.
A calculation package, not a spreadsheet
Reviewers read the equations, not cell references. Export the worksheet to PDF, Word or HTML for submittals.
Units that cannot drift
kN, m, MPa and mm⁴ mix freely; the engine converts and flags anything dimensionally wrong before it reaches a drawing.
Diagrams that solve themselves
Draw supports and loads; the engine solves the reactions and draws V and M, and reports a statically indeterminate or unstable structure instead of guessing.
What you can calculate
- ✓Beam reactions, shear and moment diagrams from a free body diagram
- ✓Bending, shear and deflection checks against allowables
- ✓Column buckling and effective length
- ✓Plane and space trusses by the method of joints
- ✓Section properties: centroids and moments of inertia of composite shapes, steel W, C, L and HSS shapes
- ✓Distributed and hydrostatic loads on bodies
Worked examples
Simply supported beam: reactions, maximum moment and bending stress
R_A = 56 kN, R_B = 46 kN, M_max = 88.17 kN·m at 2.17 m from A, and σ_max = 161.2 MPa < 207 MPa: the W310×39 is adequate in bending.
Cantilever beam: tip deflection under a point load
The tip deflects 15.32 mm, and the fixed end carries 12.5 kN·m.
Euler buckling load of a pinned column
P_cr = 548.3 kN, so the factor of safety against buckling is 4.57.

No connection needed
Works offline. The only network use is checking for updates and a one-time activation check.
AI-native, never required
The assistant drafts on the same worksheet you work on. You can do everything without it, and it never does the math: the engine does, with units, and checks it.
