Resolved conflicts:
- app/update/mod.rs: keep the dock's dock_open_at_default for the XREF
manager; take main's stable xref row identity (row_index(&id)).
- app/view/mod.rs: keep the edge layout from app::dock; drop main's copy
of the old edge-stack code (main only reformatted it there).
- ui/window/layers.rs: keep main's new visible_indices next to the
branch's view_panel.
Files the branch only reformatted take main's version. Adds the Lao
(lo-LA) translations for the new dock texts.

editor_layer_row and view_editor took Vec<String>, cloning N strings per row per frame (times two build-closure runs). Both take Arc<[String]> now; a plain borrow cannot cross the twice-run closure (E0373), hence the Arc. Cow empty-filter short-circuit for both search queries. Test: view_editor_accepts_shared_linetypes (RED first). Full suite: 2029 passed / 0 failed / 25 ignored, zero warnings.
- LAYERS opens the Layer Manager as a dockable pallet instead of a modal
dialog with a darkened backdrop. It floats over the middle of the
drawing the first time and keeps its place after that; LAYERS again
(or its close button) hides it. The table keeps its natural width and
scrolls sideways when the pallet is narrower, and the Name column
divider now drags through the dock's pointer capture. Ctrl+A selects
all layers while a layer row is selected in the open pallet.
- The Layer Manager is listed in the tab-row pallet menu like the others.
- Double-clicking a docked title bar floats the panel beside its edge;
double-clicking a floating title bar docks the panel on the side its
title bar faces.

On a non-Retina screen macOS draws the interface at 1x, which reads small
on a Full HD monitor, and there was no way to enlarge it. Options >
Display now offers an interface scale of 75–200 % in 25 % steps, applied
through the window's scale factor on top of the display's own and kept
with the user settings. It is a list rather than a slider because the
dialog rescales under the pointer as the value changes.

Display gets a command line text colour (blank keeps the theme's); it

Model Views lists named model views and places them on the current sheet

fields, sheet view record); sheet view rows get Display, Rename & Renumber
View, Set category, Place Callout Block and Place View Label Block; the

The PR pinned the codec to its fork through [patch]; codec #75 is merged
upstream and main already points at it, so the patch section is dropped.
The two windows-sys features it adds (Globalization, Identity) stay.
The exponential camera step is the right call. `0.9 ^ delta` is strictly
positive for every real delta, in and out cancel exactly where the
subtraction lost a percent of the view on every round trip, and the file's
own header has promised an "exponential feel" since it was written. Three
surfaces were left behind it, and the wider range exposed a fourth thing.
The range of the system variable. 3 to 100 is the range ZOOMFACTOR has, and
the User Preferences page was built against it; `SETVAR ZOOMFACTOR` accepts
that and nothing else again. A faster wheel is the Options window's business
instead: the slider covers the variable's own range, the field beside it
reaches 500, and a read-out says what a notch actually does ("10.0% a
notch") so the number being set is readable rather than implied. A value
above 100 therefore lives only in this application's own configuration file,
where it is nobody else's to read, and a bare `SETVAR ZOOMFACTOR` still
reports it. The bounds and the clamp live in one place now
(`settings::clamp_zoom_factor`): four literal copies of `3, 100` are what
let a surface be missed in the first place.
A floating viewport in MSPACE. It zooms its own view through
`zoom_active_viewport`, which kept subtracting: the factor reached zero at
6.67 steps, so from ZOOMFACTOR 360 up every notch inside a viewport bottomed
out on the clamp — a tenfold jump a notch, and the top third of the slider
doing nothing at all. Exponential there too, from a base of 0.85 so the
default notch still moves a viewport the 15% it always has. Each surface
keeps its own long-standing feel rather than inheriting the other's.
The trackpad pinch. `pinch_zoom_steps` was calibrated against the
subtraction (`1 - step / 10 = 1 / (1 + m)`) so that a pinch of m leaves the
view exactly 1 + m times closer — the property docs/trackpad.md documents
and the reason the gesture tracks the fingers at all. Inverting the zoom law
by hand is what let the two drift apart, so the step is asked of the camera
now (`Camera::zoom_steps_for_ratio`), which cannot drift by construction.
`pinch_is_one_to_one` recomputed the old formula rather than the camera's,
so it kept passing through all of this; it zooms a real camera and measures
the distance it lands at instead.
Also: `zoom` had a floor and no ceiling, and zooming out multiplies. At
ZOOMFACTOR 500 a notch out is x2.4, so about ninety notches — a couple of
seconds of scrolling — ran the distance past what an f32 far plane
(`distance * 1000`) can hold, and the viewport went black on an infinite
projection. A degenerate pinch magnification of -1 or beyond reached the
same place through the other side. Both are bounded now.
Also: two doc comments quoted the linear law (`zoom_view_at_cursor` and the
one on `pinch_zoom_steps`), and docs/trackpad.md stated the pinch identity
and claimed the tests covered it against the camera. All updated, with what
a notch does and where each surface's range comes from written down.
Tests, each confirmed against the behaviour it describes: the zoom law at
every factor the application can hold (positive, monotonic in the setting,
in and out cancelling), the ceiling under a long scroll out in both
projections, the published inverse and what it does with a nonsense ratio,
the viewport factor and a real viewport zoomed three notches at the top of
the range, the SETVAR range including a value the Options field set, the
Options field (above 100, above the ceiling, cleared, not a number), its
agreement with the slider, Close putting both the value and the field back,
and the read-out's percentages. 1882 lib tests pass.
The two new Options strings are not in the locale catalog yet, so they
render in English until it is regenerated.

Bug:
Message::TabClose carried a vector index captured when the view message
was built. Closing several tabs in one batch (Close All / Close Others
with unsaved-changes dialogs, or a queue of continuation updates) let an
earlier close shift the vector before a later TabClose(idx) was handled:
self.tabs.remove(idx) either panicked (index past the end) or closed a
different tab than the one the user confirmed.
Reproduce:
1. Open several drawings and modify each so they all prompt on close.
2. Use Close All, or close two tabs in quick succession so both messages
are handled in one batch.
3. Before: panic in remove(idx), or the wrong tab closes while the tab
the user chose stays open (or its work is lost).
4. After: the chosen tab closes; an id already closed by an earlier
message is a no-op.
Fix:
TabClose now carries the tab's stable u64 id, resolved to a vector
position when the message is handled, not when it is built;
PendingClose::Tab stores ids the same way. All construction sites pass
tab.id (a raw usize index no longer type-checks), and
DocTabCloseAll/DocTabCloseOthers build their queues from live ids at
handling time. A missing id means the tab is already gone, so the
handler returns Task::none().
Picking the cloud opens the Extract Section Lines from Point Cloud

POINTCLOUDCOLORMAP asks for a cloud (or None for the drawing's default

elevation tabs with the scheme list, New / Delete / Rename, number of
colours (2-25, resampled along the scheme), blend between the ends,
reverse, gradient or bands, the colorized range, the out-of-range
choice and, for elevation, the cloud's extents or a fixed range with its
band height. OK / Apply write the drawing's colour map (created under
ACAD_POINTCLOUD_COLORMAP_DICT when missing) and the cloud's colouring in
one undo step; Make stylization current sets the tab's stylization.
Values outside a scheme's range take the end colours, the scan colours

reference's prompts, the External References palette lists point clouds
(unload, reload, detach, path), and definitions keep the header extents.

- Insert > Reference: the PDF Attach button becomes an Attach Underlay menu
(PDF / DWF / DGN); its face runs the last one chosen.
- DWFATTACH, DGNATTACH and ATTACH on a .dwf/.dwfx/.dgn open the Attach
dialog for that kind: sheets or models with thumbnails (one chosen),
placement, path type, file details with the sheet / model size, and for
DGN the conversion units (sub units offer 1 / sub units per master as the
scale).
- DGN V8 true colours come from the ExtendedColors record packed in the
non-model attributes stream; the colour word's high part numbers them.
- A DGN model's extent includes each text's box (its length along the
baseline and 1.5 x its height), as the reference sizes a model.
- DWFx text uses the family named in its embedded (deobfuscated) font.
- DWF contrast pivots at 0.73 once colours are turned over for a dark
background.
- Hairline strokes are drawn solid one pixel wide, and underlay rasters are
made at or below their size on screen so those lines stay unbroken.

The codec and kernel repositories and crates are renamed opencadcodec and
opencadkernel. Inside OCS they are depended on under short keys, so code
reads `codec::`, `kernel::` and the new `graph::` (opencadgraph, the node
graph engine). File-format and protocol spellings stay as they were: the
ACIS product id `acadrust`, the ACADRUST_* switches and the plugin
version keys `acadrust_version` / `acadrust_source`.
A button left of MCP on the command line opens a translucent node graph
over the viewport, with a palette of object, input, math, logic, list,
text and geometry nodes added by click or drag. An object node owns
drawing entities and its rows are the Properties panel's own rows for
them: the single-object page is extracted from refresh_properties as
entity_property_sections, values use the control protocol's
property_json, and writes go through set_property_value with a property
target override, so the panel, MCP and the graph share one read/write
path. A list reaching an object row makes one entity per element. Each
graph action is one undo step; the canvas pans and zooms.

Implement the complete Block Definition dialog window launched via BLOCK
and BMAKE commands, featuring standard CAD layout, workflows, and entity
creation pipelines.
- Dialog UI & Layout:
- 2-column compact CAD grid with synchronized vertical heights (580 × 390px).
- Editable combobox with existing block names, invalid character validation,
and inline redefinition badge.
- Multi-line text editor widget for block descriptions (replacing single-line input).
- Quick Select (QSELECT) button integration restoring dialog state upon completion.
- Confirmation guard when attempting to redefine an existing block definition.
- Centered radio buttons, clean coordinate inputs, and accessible keyboard shortcuts.
- Base Point & On-Screen Workflow:
- BlockOnScreenCommand strictly enforces prompt sequencing: Base point is
prompted before object selection.
- Dynamically recalculates world_to_block and block_to_world affine transforms
when base point is specified on-screen, preventing stale (0,0,0) normalization.
- Supports Retain, Convert to block (INSERT placement), and Delete modes.
- Explode Enforcement:
- Guarded EXPLODE command to prevent decomposing blocks flagged as non-explodable.
- Dynamic Themed Icons:
- Added pick_point.svg, select_objects.svg, quick_select.svg, and warning_triangle.svg.
- Routed all icons through the semantic theming engine so line work (#B4B6B9)
and accents (#6DB7ED) adapt automatically to the active theme.
- Tests:
- Added unit tests for retain/convert/delete modes, redefinition, explodable flag,
on-screen base point transform recalculation, and command sequencing.
The Options window used to commit every control the moment it was
touched, with no way back but re-editing. It now works like the Drafting
Settings window: changes still show at once (a theme, a cursor size or a
language is seen immediately), but nothing is committed until Apply or OK.
Close — and the window's × or Esc — puts everything back the way it was
when the window opened or Apply was last pressed, asking first when there
is something to lose.
The commit point is a snapshot of the persisted configuration plus the
drawing variables the 3D Modeling page edits (with the drawing's modified
flag), so every control the window has or gains is covered without being
registered; reverting re-applies the snapshot the way start-up does and
re-bakes text or regenerates solids when those settings moved.
The "unsaved changes" guard is now a shared modal helper used by both
windows.

- PSETUPIN / -PSETUPIN: with no arguments a file picker offers the chosen
drawing's named page setups in the Plot dialog; `PSETUPIN <file>` opens
the same chooser on that file; `PSETUPIN <file> *` or
`PSETUPIN <file> name,name` import straight away. Same-named setups are
replaced, the import is one undo step, and the report counts both.
- The Plot dialog's page-setup list gains "Import…": the chooser shows the
source drawing's setups with a tick each, All, Import and Cancel, and
selects the first imported setup afterwards. The source is read off the
UI thread with the same reader the editor uses for its own setups
(`scene::document_page_setups`), and handles that only meant something
in the source drawing (plot view, visual style) are dropped on import.
- Options → General → Plotting: "Show the page setup for new layouts"
opens the Plot / Page Setup dialog whenever a layout is created
(persisted with the plot preferences).
Tests: the document reader, the command (all / named / unknown / missing
file / undo) against a drawing saved by the app, the chooser flow, and the
new-layout option. Nine new strings in all 21 locales.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Plot dialog:
- "Units" (millimetres / inches) is the page setup's own unit: the offsets
and the custom scale are shown in it, the stored ratio converts with it
so the plotted result and the paper space's unit stay the same
- "Custom: [paper] mm = [drawing] units" spells the picked scale in that
unit and accepts a typed ratio, which selects the list's name for it or
becomes a ratio entry of its own
- "Hide paperspace objects" is the page setup's plot-hidden flag; it is no
longer derived from the "Hidden Line" shade mode
- "Save changes to layout" (paper layouts, on by default) writes the dialog
into the layout when a plot is sent; previews never touch it
- offsets are labelled in the page-setup unit and kept in millimetres in
the file
System variables (typeable, through SETVAR, listed by SETVAR ?):
- PLOTOFFSET, PAPERUPDATE, PLOTROTMODE, PLOTTRANSPARENCYOVERRIDE and
BACKGROUNDPLOT live with the persisted plot preferences: the plot origin
counts from the printable corner unless PLOTOFFSET says the paper edge;
a printer that does not list the sheet either warns or switches to its
default sheet; transparency can be forced on or off; BACKGROUNDPLOT bit 1
is the dialog's background switch and bit 2 drives batch plots
- CTAB and TILEMODE read and switch the current layout
Tests cover every new control and variable; six new strings in all 21
locales; the Plot dialog grows to 940×690 for the two extra rows.

The Display page could only take a typed #RRGGBB, which is precise but
no way to choose a colour by eye. The swatches are now buttons that
open a wheel.
The wheel does not replace the hex field, it sits beside it: typing an
exact value stays the quickest way to reproduce a known colour. On
submit it hands a hex string to the existing ModelSpaceBgChanged and
friends rather than writing the config itself, so the two routes
cannot drift apart on validation, persistence, or the MatchTheme
fallback an empty field triggers.
Also stops the Browser shipping in the default dock layout. It was
added to the right edge, which shifted the block palette to index 1
and broke four dock tests that encode the existing arrangement. Those
tests were right and the change was wrong: the earlier commit claimed
to leave the layout alone. BROWSER now docks the panel on first use,
so nobody's edges rearrange on upgrade for a panel they never asked
for.
The toolbar Help button was a disabled tip that could never be clicked. It now opens a modal window explaining the manager on the web build: read-only reference list, disabled Attach/Refresh/Change Path (no filesystem access or native file pickers, so no add/reload/repath and no previews), nested read-only rows, and saved-drawing requirement for relative paths.
Includes a Report-an-issue button opening the GitHub issues page and a Close button; wired as ModalKind::XrefHelp through the shared modal frame so dismissal works on native and web.
The viewport context menu is now built from a pure model
(ui::popup::context_menu) rendered by the overlay: while a command runs it
offers Enter / Cancel / every keyword of the command's options() with the
keyword shown as a hint, a Recent Input submenu and M2P; when idle it offers
Repeat, Recent Input, Clipboard, Undo/Redo with history labels, the edit
block (Erase/Move/Copy/Scale/Rotate/Mirror/Draw Order), Isolate, Pan/Zoom,
selection tools, Properties and Options. The default row is anchored under
the pointer and the menu is keyboard-navigable (arrows, Enter, mnemonic
letters; any other key closes it and types into the command line).
Right-click behaviour is a user preference (Options → User Preferences,
SHORTCUTMENU / SHORTCUTMENUDURATION): shortcut menu (commercial solutions default),
time-sensitive, or the previous Enter-first cycle.
LINE gains options() (Close/Undo/eXit).

Properties… next to the printer used to open the CUPS web interface in a
browser. It now edits the driver options of the *selected* printer the
way LibreOffice's Properties… does, without leaving the plot dialog:
- CUPS platforms (Linux, any desktop; macOS): an in-line editor lists the
printer's PPD options as `lpoptions -l` reports them — media type,
colour mode, quality, duplex, trays, scaling — with readable choice
labels, Reset / Cancel / Apply. Apply keeps only the choices that differ
from the driver defaults, per printer, in the plot config, and every job
for that printer passes them as `lp -o key=value`. Where CUPS cannot
answer, the desktop's printer settings panel opens instead of a browser.
- Windows: the driver's document-properties sheet (`DocumentPropertiesW`
with prompt, owned by the main window) and, on OK, the result stored as
the user's printing preferences for that printer (`SetPrinter` level 9),
which the job honours. `printui /e` (printing preferences) replaces the
device-properties sheet as the fallback.
The desktop print portal was tried first and dropped: GTK 4's print
dialog loses the preselected printer when the default queue is listed
before it, so the dialog always opened on the wrong printer.
Dialog layout: the modal grows to 940×620; Printer / plotter and Paper
size share a line with their pickers (long queue and media names now fit);
Copies + Properties… and Custom… sit beneath; the custom-sheet editor
labels each margin (Left / Right, Top / Bottom) and shows the unit.
Also recognises `none_device`, AutoCAD's stored spelling for "no plotter",
and writes it back unchanged.
Tests: `lpoptions` parsing and keyword humanising, the editor flow (load,
stale answer ignored, set, apply, remember, reset, error, cancel), device
name round-trips including `none_device`.
