Building Project
Lay out shear walls on each floor's diaphragm, distribute the story forces, then design every element from its own tab — no page reloads. Finish with a 3D model of the building.
Floors & story forces
Level 1 is the lowest story (base). Forces are the lateral force applied at each level; the engine accumulates story shear downward by wall id. Center of mass defaults to the diaphragm centroid.
| Level | Story ht (ft) | Shape | Lx (ft) | Ly (ft) | Diaphragm | Fx (lb) | Fy (lb) | CoM x | CoM y |

Force distribution
Press Run distribution to compute center of rigidity, eccentricity (incl. 5% accidental), torsion and per-wall shears. A design tab is then created for every wall and diaphragm.
3D model
Drag to orbit · scroll to zoom · right-drag to pan. Walls are colored by direction; height stacks by story. Run the distribution first to populate it.
