What it does
Arranges and tidies Simulink block diagram layouts with the model_edit layout engine. Use when the user asks to fix, clean up, tidy, straighten, or rearrange a layout, when blocks overlap or lines cross, when specific blocks need re-placing, or when grouping blocks into or expanding a subsystem.
Arranging Simulink Layouts
Re-place blocks with the SATK layout engine in model_edit. Move as little of the user's diagram as the request allows.
When to Use
- "Fix / clean up / tidy / straighten / rearrange the layout", "make it readable"
- Blocks overlap, lines cross or run through blocks, a few blocks landed in odd places
- "Move these blocks", "line these up", "sort out the blocks I just added"
- Grouping blocks into a subsystem, or expanding a subsystem into its parent
When NOT to Use
- Adding, connecting, deleting, or configuring blocks: use
building-simulink-models. Layout already runs automatically after everymodel_editcall. - Stateflow chart layout: the
layoutop is Simulink-only. A chart scope accepts only a full re-layout (operations[],layout_mode"full"), which moves every element, so ask first.
Set Expectations
- You drive an automatic layout engine. You don't place blocks pixel by pixel. Say so if the user expects hand-tuned placement.
- Ctrl+Z is not reliable for agent edits, including layout. Don't offer undo. Before any layout that moves many blocks, recommend that the user saves the model (or a copy) first.
- The first layout in a MATLAB session can take about 20 s while the engine starts. Later calls take 1, 2 s.
Choose the Method
Selective layout is the default. A full layout of a diagram the user has arranged by hand discards their arrangement, so ask before running one.
| Situation | Method |
|---|---|
| A few blocks are messy, overlapping, or just added | {"op":"layout","targets":[...]} with layout_mode "incremental" |
| The whole scope is a mess and the user agrees that everything moves | operations [] with layout_mode "full" |
| The user explicitly asks for Simulink's own tidy-up | Format > Auto Arrange / Simulink.BlockDiagram.arrangeSystem, and only on request |
| The user wants an exact placement | configure with Position through model_edit |
