Slab → beams → columns. Live FE.

Sketch any rectilinear-polygon slab on a grid (L-shapes, T-shapes, slabs with holes — just toggle cells on or off), drop columns and axis-aligned beams. The tool meshes the active cells with quads, hangs a 1D Member on every beam line and runs a linear FE solve in your browser — giving you live shear / moment / axial diagrams plus exportable SVG and PNG drawings.
