# Chassis and Enclosures
Covering the Hammond pedal and amplifier chassis lineup with a `ChassisPanel` datasheet, and
shipping the common pedal enclosures as exploded five-panel factory building blocks.
The Hammond die-cast and amplifier chassis lineup as a datasheet on a single `Enclosure`
component that draws either one panel or an exploded view of the whole box.
## 1. Current state
- `ChassisPanel` (`diylc-library`, `org.diylc.components.chassis`) is a two-point
`AbstractShape` on the `CHASSIS` layer with an `Edge Radius`. One instance is one side of a
chassis; its `@AiNote` already fixes the exploded-view convention (top in the centre, front
against its upper edge, back against its lower edge, left and right against the side edges).
- Four factory variants in `variants.xml` (`125B`, `A`, `B`, `BB`) store nothing but corner points
and a 5 mm radius. Their sizes are not Hammond's (the `125B` variant is 122.3 x 67.1 mm, the
1590N1 drawing says 121.2 x 65.5).
- Factory building blocks (`import-defaults/blocks.xml`, three entries) are imported once, behind
the boolean `DEFAULT_BLOCKS_IMPORTED_KEY`; blocks added later never reach existing users.
- `ChassisPanel` (`diylc-library`, `org.diylc.components.chassis`) is shown as **Enclosure** in the
new **Hardware** category, with instance prefix `ENC`. The class name is unchanged, so files,
favourites, recent components and variants, all keyed by class, are unaffected. The three
cutouts, Drill Hole and Dial Scale moved to Hardware with it.
- It is a two-point `AbstractShape` on the `CHASSIS` layer. The control points are the top panel.
With `Height` > 0 the sides are unfolded around it (front above, back below, left and right to
the sides; never the bottom), per `Sides`: `All`, `Front and Back` or `None`, set `Spacing`
(default 0, edge to edge) apart from the top.
- A new enclosure is an upright 125B with all sides, square corners and no spacing (`DEFAULT_*`
constants; the size matches its datasheet row).
Old files are unaffected: XStream runs no constructor or initializer, so their saved size,
radius and empty value stay and their missing `height` keeps them a single panel. `Height` null
(old files) or 0, or `Sides = None`, draws a single panel, as `ChassisPanel` always did.
- A datasheet of 132 Hammond and generic models (§4) sets `Value` (the model), the top panel size
and `Height`; it leaves `Radius` alone. One component is one enclosure, so the BOM lists `Enclosure / 1590BB`.
- The four old factory variants (`125B`, `A`, `B`, `BB`) are withdrawn as `deletedOn` stubs.
- Composites take the lowest layer of their children (`ComponentProcessor.getZOrder`), so a
composite of chassis panels sits on the Chassis layer, under parts placed before it, and
follows that layer's hide/lock. Done; see §3.1.
building block made of chassis parts sits on the Chassis layer and hides and locks with it.
## 2. Design decisions
| # | Decision | Rationale |
|---|---|---|
| D1 | Chassis sizes move to a datasheet, `datasheets/ChassisPanel.datasheet`, two creation steps (Group > Model) | Same mechanism as `DIL_IC` and `Resistor`; the AI can name a model; one row serves every side of the enclosure (D3). |
| D2 | Row format `Group,Model,Length,Width,Height,Radius`. Sizes in mm unless a unit follows (`8 in`), parsed like `Resistor.parseDatasheetSize` | Pedal drawings are metric, Hammond chassis are nominal inches; writing each in its native unit keeps the file checkable against the drawings. |
| D3 | `ChassisPanel` gets a `Value` property holding the model, and a new `Side` (`TOP`, `FRONT`, `BACK`, `LEFT`, `RIGHT`). `applyModel` sets `Value` to the model and sizes the panel from the row according to its side: top = Length x Width, front/back = Length x Height, left/right = Width x Height, keeping the first control point. Changing `Side` on a panel that has a model resizes it | One class, no per-side types. `Value` is backed by `AbstractShape.value`, a `String` that every shape already serializes and nothing reads (always `""`), so no new field is needed for it; since `AbstractShape.getValue()` is typed `Void`, the getter is `getModel()` with `@EditableProperty(name = "Value")`. `side` is new and reads `null` from old files: `getSide()` defaults to `TOP`. An empty value means "free-form panel" exactly as today. |
| D4 | Top panel is drawn landscape, Length along X | Matches the four existing variants and the amp chassis front-panel orientation; pedal builders rotate (the transformer already supports it, and a composite rotates as a unit). |
| D5 | Length/Width are Hammond's outside dimensions; Height is the drillable wall: box height without the lid for die-cast boxes, outside height for 1441/1444 | The lid of a 1590 is the pedal's bottom, which the exploded view leaves out. |
| D6 | Die-cast taper is ignored: the top panel uses the outer size at the lid opening and side panels are rectangles | Hammond does not publish the floor size; the walls slope at most 2 deg, so the floor is 0.7-1.9 mm smaller per side. Recorded in §5 as unsourced. |
| D7 | The four variants are withdrawn as `deletedOn` stubs | The mechanism from the Resistor and DIP migrations (`Template.deletedOn`, `DeletedVariantsTest`). |
| D8 | Factory blocks get variant-style import tracking: each factory block has `createdOn`/`deletedOn`, the import date is stored under a new key | Mirrors `VariantManager`; lets new factory blocks reach existing users. |
| D9 | Exploded factory blocks only for the common enclosures: pedals 1590A, 1590B, 125B, 1590BB, 1590XX, 1590DD; amps 1441-10, 1441-18, 1441-28, 1441-32 (§3.4) | The block toolbar is a flat list of buttons; the full lineup stays in the datasheet. |
| D10 | A composite's z-order is the **minimum** of its children's, computed per instance | A composite occupies one slot in the stack and is drawn as a unit, so it should sit under what is placed on it afterwards. For a chassis block min = max = `CHASSIS`. For a maker board built from a board, pads and silkscreen text, max would be `TEXT` and the board would cover every part placed later; min is `BOARD`, and locking the Board layer locks the whole board. |
| D11 | Die-cast boxes come from the 1590 and 1550 series only, natural finish only, plus generic sizes such as 125B under `Others`. HWCHAS walnut chassis and rack cases are out of this change | Painted and black versions share the natural part's dimensions, and the shaped 1590 STOMP boxes (TRPB, TRPC, STPC) are sold painted only. The others are listed in §6. |
| D12 | BOM: one line per enclosure, valued by model. `getValueForDisplay()` returns the model for a `TOP` panel and `null` for any other side; `bomPolicy` stays `SHOW_ONLY_TYPE_NAME` | `BomMaker` keys rows by type + value and skips a `null` value, so an exploded 1590BB reads `Chassis Panel / 1590BB / 1` instead of five panels. Free-form and old-file panels are `TOP` with an empty value and list as they do today. An exploded block placed as a composite lists under its block name, so the block's `CompositeComponent` carries the model as its value too (§3.4). |
| D1 | One component draws the whole enclosure; no per-side panels and no exploded building blocks | Every datasheet model is an exploded enclosure in one click, the BOM gets one line per box, stretching the top drags the sides along, rotation needs no special code, and the component sits on the Chassis layer natively. Building blocks would have needed import tracking, a flat toolbar of ~10 buttons, and a per-panel BOM workaround. |
| D2 | Row format `Group,Model,X,Y,Height`: the top panel's size as placed, then the wall height, every size with its unit (`119.5 mm`, `17 in`), parsed with `Size.parseSize` like `DIL_IC` | Pedal drawings are metric, Hammond chassis are nominal inches; writing each in its native unit keeps the file checkable against the drawings. |
| D3 | `Value` is backed by `AbstractShape.value` through `getModel()` with `@EditableProperty(name = "Value")`; `height` and `sides` are new fields | `value` is a `String` every shape already serializes and nothing read, and `AbstractShape.getValue()` is typed `Void`. New fields read `null` from old files: `getHeight()` null means no sides, `getSides()` defaults to `All`. |
| D4 | Die-cast boxes up to 125 mm long (1590, 1550, 125B) are listed upright, with Hammond's length along Y; longer boxes and all 1441/1444 chassis horizontal. A new enclosure is an upright 125B. `applyModel` sets `Value`, `Height` and the top panel size, keeping the first control point and the direction the panel is drawn in | Pedals use the small boxes upright, with the jacks and DC socket on the short ends, which the front and back panels then show; bigger boxes and amp chassis are used lying down. |
| D5 | The datasheet carries no corner radius; `Radius` defaults to 0 and only the top panel uses it, the sides are drawn square | Hammond does not publish the die-cast corner radius (§5), so rounded corners are set by hand when wanted. |
| D6 | Length/Width are Hammond's outside dimensions; Height is the drillable wall: box height without the lid for die-cast boxes, outside height for 1441/1444 | The lid of a 1590 is the pedal's bottom, which the exploded view leaves out. |
| D7 | Die-cast taper is ignored: the top uses the outer size at the lid opening and the sides are rectangles | Hammond does not publish the floor size; the walls slope at most 2 deg, so the floor is 0.7-1.9 mm smaller per side (§5). |
| D8 | A composite's z-order is the minimum of its children's, computed per instance | A composite is drawn as a unit, so it should sit under what is placed on it afterwards; a maker board built from a board, pads and silkscreen text belongs on the Board layer, not the Text layer. |
| D9 | Die-cast boxes come from the 1590 and 1550 series only, natural finish only, plus generic sizes such as 125B under `Others`. HWCHAS walnut chassis and rack cases are out | Painted and black versions share the natural part's dimensions, and the shaped 1590 STOMP boxes (TRPB, TRPC, STPC) are sold painted only. |
## 3. Implementation
Step 4 depends on 2 and 3.
### 3.1 Composite z-order (core) - done
- `ComponentProcessor.getZOrder(IDIYComponent<?>)`: for a `CompositeComponent`, the minimum over
its children, recursing into nested composites; a childless composite and any other component
use the type's z-order. Not cached: a type lookup is a map hit and composites are few.
- Every class-level layer read goes through it: `Presenter` insertion (`addComponent`,
`addComponents`), hidden and locked layers, `selectAll(layer)`, send to back / bring to front;
`GroupAndLockIndex.isLocked`; `ComparatorFactory.getComponentZOrderComparator`; the `[L#]` tag
in `ExplorerPane`, which now shows composites too.
- Paint order is the project list order, so existing files render the same; only hide/lock and
future insertion change. `flexibleZOrder = true` stays.
- Tests: `CompositeComponentTest` (chassis-only, mixed, nested and childless composites; layer
lock; comparator) and `PresenterTests.testChassisCompositeIsPlacedUnderExistingComponents`.
- Every class-level layer read goes through it: `Presenter` insertion, hidden and locked layers,
`selectAll(layer)`, send to back / bring to front; `GroupAndLockIndex.isLocked`;
`ComparatorFactory.getComponentZOrderComparator`; the `[L#]` tag in `ExplorerPane`.
- Tests: `CompositeComponentTest` and
`PresenterTests.testChassisCompositeIsPlacedUnderExistingComponents`.
### 3.2 `ChassisPanel` datasheet (library)
### 3.2 Enclosure (library) - done
- `enableDatasheet = true, datasheetCreationStepCount = 2, datasheetModelColumn = 1`,
`implements IDatasheetSupport`, `ChassisPanel(String[] model)` constructor.
- `getModel()` / `setModel()` over the inherited `value` field as `Value`, and a new serialized
`side` whose getter tolerates `null` (D3). Override `getValueForDisplay()` for the BOM (D12).
- `@AiNote`: a datasheet model is a Hammond part number such as 1590BB or 1444-32 and is stored as
'Value'; it sets the panel size for the panel's `Side`, so set `Side` before or together with
the model. Only the top panel carries the enclosure into the BOM. "125B" is a generic size
sold by several makers (about 122 x 66 x 40 mm with the lid, often with thinner walls) and has
its own row under `Others`; its Hammond equivalent is 1590N1.
- `ChassisPanel.datasheet` from §4. Rows are listed per group in the order given there.
- `variants.xml`: `125B`, `A`, `B`, `BB` become `deletedOn` stubs; extend `DeletedVariantsTest`.
- `ChassisPanelDatasheetTest`, modelled on `ResistorDatasheetTest`: every row parses; each side
gets the expected size; changing `Side` resizes; a panel from an old file (empty value, null
side) keeps its geometry; the BOM lists one line per top panel, valued by model, and none for
side panels.
- Localization: `Side`, `Top`, `Front`, `Back`, `Left`, `Right` in
every `lang/` file. Fix the description typo "withouth".
- Regenerate `catalog_full.json` as the Resistor change did.
- `ChassisPanel` implements `IDatasheetSupport` (two creation steps, model column 1) with a
`ChassisPanel(String[] model)` constructor; rows in `datasheets/ChassisPanel.datasheet`.
- `getSidePanels()` derives the side rectangles from the top panel's normalized corners and
`Spacing` (a new field; `null` from files reads as 0); `draw()`
fills them before `stopTracking()` so they take part in hit-testing, and outlines them with the
top. `getValueForDisplay()` returns the model.
- Category `Hardware` for `ChassisPanel`, the three cutouts, `DrillHole` and `DialScale`. New
language keys in every `lang/` file: `Hardware`, `Sides`, `All`, `Front and Back` (`Height`
and `None` existed). `catalog_full.json` and `catalog_index.json` regenerated.
- Tests: `ChassisPanelDatasheetTest` (every row applies, unique model names, inch rows,
radius left alone by a model, side layout for All / Front and Back / None, spacing, sides follow a stretched top, no height, old-file
panel, BOM).
### 3.3 Factory block import tracking (core)
### 3.3 Verify
- New `org.diylc.core.FactoryBlock` (`name`, `createdOn`, `deletedOn`, `components`), the shape of
`Template`. `blocks.xml` becomes a list of these; the user's `BLOCKS_KEY` map is unchanged.
- `BuildingBlockManager.importDefaultBlocks` mirrors `VariantManager`: import a block when its
`createdOn` is after the stored `DEFAULT_BLOCKS_IMPORT_DATE_KEY` and the user has no block of
that name; remove it when `deletedOn` is after the import date.
- Migration: the three existing blocks keep `createdOn = null` and are imported only when the
legacy `DEFAULT_BLOCKS_IMPORTED_KEY` is false (a fresh install), so users who deleted them do not
get them back.
- Test alongside the variant import tests: fresh install, upgrade from the boolean flag, new block
after an import, deleted block, user block with a clashing name.
### 3.4 Exploded blocks
- Ten blocks named `Hammond <model> (Exploded)`, or `<model> (Exploded)` for a generic size
(`125B (Exploded)`): the six pedal enclosures from D9 and four amp chassis, one per size class.
The amp picks are the steel 1441 sizes amp builders and kit
suppliers stock (Tube Town, an amp-parts shop, carries 1441-10, -18, -28 and -32); steel over
the 1444 because builders warn that thin chassis sag under heavy transformers.
| Class | Typical build | Block | W x D x H | Why this size |
|---|---|---|---|---|
| Small | Tweed Champ (5F1) | 1441-10 | 8 x 4 x 2 in | Closest Hammond to the original 5F1 chassis (8-3/4 x 4-1/8 x 2-5/8 in). |
| Medium | 18 W Marshall (TMB) | 1441-18 | 13.5 x 5 x 2 in | The Hammond size suggested for 18 W builds; dedicated 18 W chassis are similarly long and narrow (17 x 6-1/2 x 2-1/2 in), which fits the in-line tube row. |
| Larger | 50 W Plexi / JTM45 | 1441-28 | 16 x 8 x 3 in | 16 x 8 x 2-3 in is the size quoted for 50 W Marshall builds; 3 in clears the transformers. |
| Large | 100 W modern (SLO-style) | 1441-32 | 17 x 10 x 3 in | Largest common format; room for two channels, four power tubes and large iron. |
- No source names a Hammond for the SLO specifically (the real head is 25 in wide, wider than
any Hammond chassis); 1441-32 is a size judgement.
- Each block is five `ChassisPanel`s with `Value` (model) and `Side` set; the block's composite
value is the model as well, so the BOM line reads `Hammond 1590BB (Exploded) / 1590BB`. With the top at (0,0)-(L,W): front (0,-H)-(L,0), back (0,W)-(L,W+H), left (-H,0)-(0,W),
right (L,0)-(L+H,W). Edge radius on the top panel only.
- Generate the XML once from the datasheet rather than by hand, and add a test that every panel of
every factory chassis block matches its datasheet row and touches its neighbours edge to edge,
so the two cannot drift.
### 3.5 Verify
`mvn -q test` (spans core and library), then offer the regression suite: §3.1 changes hide/lock
behaviour of existing composites and §3.2 touches serialization.
`mvn -q test`, then the regression suite: the z-order change alters hide/lock of existing
composites, and `ChassisPanel` gained serialized fields and a new category.
## 4. Datasheet rows
Sources: Hammond per-part drawings, `https://www.hammfg.com/files/parts/pdf/<PART>.pdf`; series
tables on hammfg.com (1590, 1590-STOMP, 1441, 1444). Die-cast sizes are drawing outside dimensions
at the lid opening; heights are the box without the 4 mm lid. Chassis sizes are Hammond's nominal
outside W x D x H. Radius 5 on die-cast boxes is carried over from the old variants, **unverified**
(§5); sheet-metal chassis are drawn square.
outside W x D x H. Rows of die-cast boxes up to 125 mm long have their two top sizes swapped so
they place upright (D4). There is no radius column (D5).
Die-cast boxes are grouped by series only (1590, 1550), in Hammond's catalogue order, and only
natural-finish (unpainted) part numbers are rows. Chassis are grouped by family, then height. The
1590 group has 37 rows; the toolbox already splits a datasheet submenu longer than
`MAX_MENU_ITEMS` (30) into ranged submenus, so it needs no further split.

- Factory building blocks are still imported once, behind the boolean
`DEFAULT_BLOCKS_IMPORTED_KEY`, so a block added to `blocks.xml` later never reaches existing
users. Fix by giving factory blocks `createdOn`/`deletedOn` and an import date, as `VariantManager`
does, when a new factory block is next needed.
- Configs older than class-keyed variants store keys like `Electro-Mechanical.Chassis Panel`;
`VariantManager`'s upgrade maps them by the current category and name, so such variants would
not carry over. Map the legacy name if it turns out to matter.
