How it works

  1. Ten-storey concrete building model
    01

    Model

    • Orthogonal, radial or skewed grids
    • Trace over the architect's DXF
    • Generators for portals, towers, tanks and culverts
  2. Deflected shape contoured on the frame
    02

    Analyse

    • 3-D finite elements: shells and frames
    • Combinations from your code's tables
    • Wind to EN 1991-1-4, BS 6399-2 or CP3
  3. Frame coloured by design status
    03

    Design

    • Every member checked, pass or fail
    • Results shown on the model
    • Calculation sheets cite each clause
  4. Slab reinforcement layout drawing
    04

    Detail

    • Beams, columns, slabs and foundations
    • Bar marks, laps and link zones
    • Built-in drawing editor, DXF out
