Build with AI
Edit an existing structure
Before each request, the AI reads the open model: the classes, the profiles and where each bar is. That is why short requests work, one at a time. In the sketches, magenta marks what each request created or changed. In the technical perspective, the same crop appears before and after the request.
A real sequence
Four requests in a row on the same model. In the table of each step, the magenta square marks the class that was added or changed.
1Frames only
You15 x 24 m shed, 5 m eave height, frames every 6 m, gable roof, just the frames for now, no purlins and no bracing.
AI5 frames with a 15 m span spaced every 6 m (Z from 0 to 24 m), 5 m eave height, ridge at 5.75 m (10% slope). W250x33 columns and W200x22 beams with pinned bases. Roof panels generated.

2Purlins
YouPut the purlins every 1.5 m.
AIC 150x50x17x2 purlins spaced every 1.5 m in horizontal projection over the roof beams in every frame bay (Z = 0 to 24 m), fitted over the beams.

It does not redraw the frames: it adds the purlins and fits them over the beams.

3Bracing
YouAdd X bracing in the end bays, on the roof and on the walls.
AIX bracing system added in 16 mm round bar (A36 steel) on the walls and on the roof in the end bays (Z=0 to 6 m and Z=18 to 24 m).

Swap columns for lattice columns
A bigger swap, on the 12 x 30 m shed from the previous page. Here the AI asks first, because a lattice column has choices the text does not state.
Lattice columns in place of the columns
YouReplace the columns with lattice columns.
AIBefore building, it asked:
- What width (depth) should the lattice column have?40 cm (recommended for 6 m)30 cm50 cm
- Which profile do you prefer for the column chords?Two C profiles (e.g. C 100x50)SHS 60x3 square tubeDouble angle
- Which lacing pattern?Warren truss (alternating diagonals)X truss (crossed diagonals)Pratt truss (verticals and diagonals)
Answer and buildDecide for me
YouTapped Decide for me.
AIReplaced the 12 W200 columns with 40 cm lattice columns, with C 100x50 chords and Warren diagonals in L 30x30x3 angles.
AICan I delete the Columns class and its 12 bars? Ctrl+Z undoes it.

It drew 84 chords and 84 diagonals, and only asked to delete the old columns. They were removed after the tap on Delete.

Undo and interrupt
- Ctrl+Z undoes the whole round at once, not bar by bar.
- Stop or Esc interrupts the build midway.
- At the end of each round the editor checks the model. If something is missing, it says what and offers Complete what is missing or It is fine as is.
