Build with AI
New structure: from text to steel
Four real requests and what the AI delivered. On the left, the request, the conversation and the numbers of the model. On the right, the sketch with colors by bar type and, below it, the same structure in CalcSteel’s technical perspective, with the spots worth a closer look.
Where it is: the Build with AI button sits at the bottom center of the editor. On a phone, it is the round button in the middle of the bottom bar.

Shed with purlins and bracing
YouMake a 12 x 30 m shed, 6 m eave height, frames every 6 m, gable roof with a 10% slope, purlins every 1.5 m and X bracing in the end bays.
AIThe request already had everything it needed, so it built right away, without asking.
AI, when doneSteel shed of 12 x 30 m, 6 frames spaced at 6 m, 6 m eave height, ridge at 6.60 m (10% slope). W200 profiles in columns and beams, C150 purlins every 1.5 m and tie rod bracing in the end bays.

The purlins are split where they cross the beams, so the model has more bars than drawn pieces.

Mezzanine
You6 x 8 m mezzanine at 3 m height, I-section beams, floor for 5 kN/m².
AIBefore building, it asked:
- How should the columns be laid out?4 columns at the corners (6 m and 8 m spans)6 columns (the 8 m span split in half at 4 m)
- Which floor type?Wall panel or plywood with secondary beams every 0.8 mSteel deck with secondary beams every 2 m
- Which profile do you prefer for the columns?W profile (rolled I/H)Square tube (SHS)

Truss roof
YouTruss roof with a 15 m span and 20 m length, trusses every 5 m supported on 5 m columns.
AIBefore building, it asked:
- Which type of profile do you prefer for the columns and trusses?Rolled W profiles in the columns and tubes in the trussCold-formed profiles (U/C) throughoutStructural tubes (square or rectangular)
- What slope or rise do you want at the truss ridge?10% (0.75 m at the center)15% (1.13 m at the center)20% (1.50 m at the center)
- Should I add the roof purlins now?Yes, with purlins every 1.5 mNo, only frames and trusses for now

AI, when done15x20 m truss roof with W200x22 columns (H=5 m), tubular trusses every 5 m with a 1.13 m rise (15%), C 100x50x15x2 purlins every 1.5 m, pinned supports at the base, panels and live and wind loads applied.
Editor, at the end of the roundDid not apply 1 action: fitting the purlins into the top chord. The purlins were left resting on the chord, and the notice offers to complete what is missing.
