A day of pan/zoom that had suddenly become unusable on a 1.2M-entity
drawing turned out to be no regression at all: an unattended NVIDIA
userspace update had been applied without a reboot, the Vulkan ICD could
no longer talk to the still-loaded kernel module, and wgpu silently fell
through to Mesa's llvmpipe. Nothing in the app said so. iced picks the
adapter and names it only under RUST_LOG, so the only evidence was 32
`llvmpipe-N` threads in /proc. The same silence covers WARP on Windows,
SwiftShader in browsers, and the case where wgpu finds no adapter at all
and iced quietly draws the chrome with tiny-skia while the shader widget
is dropped, leaving a blank viewport. This commit makes all of that
visible, on every platform, without new dependencies.
Detection (src/scene/pipeline/mod.rs)
-------------------------------------
`GpuStatus` is derived from two signals:
* `record_gpu_adapter`, run from `MultiPipeline::new` (once per device,
next to the existing uncaptured-error handler), reads
`Device::adapter_info()`, prints one `[gpu] adapter: <name> (<backend>,
<device type>, driver …)` line — stderr natively, `console.warn` on the
web, which has no stderr — and keeps a copy.
* `note_scene_draw`, run from `ViewportPane::draw`, counts how often the
viewport asked for a primitive. Every renderer makes that call; only
wgpu goes on to `prepare` and create a device. Three draws with no
device ever recorded therefore mean the primitive is being dropped.
The verdict is one of `Unknown`, `Hardware`, `Software(adapter)` or
`NoRenderer`. `Software` is `DeviceType::Cpu` — what Vulkan reports for
llvmpipe, DX12 for WARP and GL for a renderer string that gives it away —
plus a name match on the fallbacks browsers expose (SwiftShader, llvmpipe,
lavapipe, "Microsoft Basic Render"), because the WebGPU backend reports
every adapter as `Other` (gfx-rs/wgpu#8819). Metal has no software device,
so on macOS only `NoRenderer` can occur (a VM without a GPU); it is caught
by the draw count like everywhere else.
`gpu_status_if_changed` costs one atomic load per app message: a
generation counter moves only when a device is recorded or the draw count
crosses its threshold, so the app re-derives the verdict a handful of
times per session.
Notification (src/app/startup.rs, view/modal.rs, ui/statusbar)
-------------------------------------------------------------
`refresh_gpu_status` runs after every message. On a degraded verdict it
speaks through three channels, because many users never read the command
line:
* A popup, `ModalKind::GpuWarning`, queued once per verdict through the
startup-modal queue so it waits its turn behind the file open. It names
the adapter, states the consequence (slow navigation, unstable or
missing rendering) and gives the remedy that usually applies on the
running platform: a driver update not yet followed by a reboot on
Linux, a missing driver or a Remote Desktop / VM session on Windows, a
VM without a Metal device on macOS, hardware acceleration switched off
in the browser. "Don't show again for this device" stores
`GpuStatus::identity()` in `settings.gpu_warning_silenced`; keying it by
verdict means silencing "software rendering on llvmpipe" does not
silence a later, different failure.
* A status-bar pill in the theme's warning colours, `⚠ Software rendering`
or `⚠ No GPU renderer`. It is not a `StatusPill`, so it cannot be hidden,
and it stays for the session; clicking it reopens the popup, silenced or
not.
* A command-line entry through the new `CommandLine::push_warning`, which
is styled like an error but deliberately does not touch `last_error` /
`error_revision`: automation reads those to decide whether the command it
just ran failed, and a graphics warning is not a failed command.
`subscription()` requests frames only while the verdict is `Unknown` on a
document tab (the Start page draws no viewport), so the probe costs one
frame on a working GPU, three on none, then stops.
Verification
------------
* Live on the machine that had the incident, with the Vulkan loader
restricted to Mesa (`VK_DRIVER_FILES=…/lvp_icd.json WGPU_BACKEND=vulkan`):
popup → OK → pill → click reopens; "Don't show again" → restart → pill
only, no popup.
* `gpu_tests::the_adapter_is_reported_once_per_device` (ignored, needs an
adapter) asserts the classification on a real device; it was run on both
llvmpipe (`Cpu`) and an NVIDIA GT 1030 (`DiscreteGpu`).
* Unit tests cover the name heuristic, the verdict function, the identity
rule, the warning text with an adapter name that itself contains
parentheses and commas, the settings round trip and the command-line
semantics. New strings are in all 21 locales as the `gpu` Fluent group.

- Enable fallback font metrics for HarfBuzz shaping in TTF glyph resolver
- Implement Unicode Bidirectional Algorithm (UBA) paragraph base direction detection
- Anchor right-to-left paragraphs to right container boundaries by default
- Reorder line atoms with base direction level to preserve neutral punctuation attachment
- Right-align RTL single-line TEXT and handle editor caret placement on RTL glyphs
The MTP/M2P midpoint-between-two-points modifier existed as a typed transparent command only. Add it to the Shift+RMB snap override menu as an icon-only cell after Parallel (hover tooltip, no text) with a new osnap/mtp.svg marker, plus a context-menu entry while a point prompt is active.
value toggle, and redesigned constraint-ribbon icons
Properties panel:
- New "Parameters" section (shown with no selection) listing every named
parameter with inline name/formula editing, add, and delete, backed by
new PropValue::ParamRow/ParamAddRow and command_driver handlers
(resolve_named_parameter_edit, on_prop_param_commit/_delete/_add_new).
A fresh parameter's formula now defaults to "1", not "0" — a 0-length
seed value is a genuine solver singularity for a Distance constraint
driven by that parameter, with no defined direction to grow back out of.
- New "Constraints" section (shown for a single selected entity) listing
every constraint touching it as a clickable PropValue::EntityLink that
selects the linked entities in the viewport, danger-tinted when the
constraint conflicts.
Constraint pills:
- New Options > General toggle, "Show values and parameter names on
constraint markers" (on by default, persisted). Off, every pill shows
just its bare glyph instead of glyph+driven-value/parameter-name — the
glyph alone is enough to see a constraint is present, without the value
text covering nearby geometry on a dense sketch.
Constraint-ribbon icons:
- Replaced all 18 unicode/letter glyph icons (including the plain "F",
"L", "M", "S" letters) with proper SVGs under assets/icons/constrain/,
matching the Modify section's two-color style (#B4B6B9 white / #6DB7ED
blue, consistent stroke width). Tangent reuses the Draw section's
white-arc-plus-blue-dots motif.

Arcs are now full constraint participants (center/radius via the existing
Circle-shaped solver path, plus real endpoints kept consistent by arc-rules
CurveValue constraints); adds Diameter/DistanceX/DistanceY/ArcLength/Normal
constraint kinds and initial Ellipse entity support (center-based
constraints only). DWG-native class mappings and gaps (ArcLength, Ellipse)
are grounded against real ObjectARX headers rather than guessed, so files
saved with DWG-native constraints stay honest about what AutoCAD can
actually represent.
Also fixes a case-sensitivity bug where a lowercase named-parameter
reference typed at a dimensional constraint's value prompt was rejected
(the command line uppercases SingleToken input before the parameter-name
lookup), and adds a "Used by" column to the Named Parameters panel.

The application has no support-file search path — the four folders it uses
are functions returning fixed paths, not settings. Rather than build a Files
page that pretends otherwise, this one answers the question people actually
open it to ask: where does this thing keep my plot styles. Each row shows the
location and opens it in the file manager, and a row whose path the platform
could not give says so with its button disabled.
General gains buttons through to the plugin manager, the keyboard shortcut
editor and the alias editor. Those three have good dialogs of their own and
are not absorbed; Options simply stops being a place you cannot reach them
from.

The ViewCube, the UCS icon, its at-origin placement and selection cycling all
have commands and status-bar pills, and all four kept their value only on the
app struct. Turn the ViewCube off with NAVVCUBE, restart, and it is back.
Nothing failed — the setting evaporated — so a checkbox for any of them would
have been a checkbox that forgets. They are persisted first, with a
round-trip test, and only then given controls.
The new 3D Modeling page carries the three view tools plus the drawing
variables that decide how solids are tessellated: ISOLINES, DISPSILH, SURFU,
SURFV, SURFTYPE, SOLIDHIST and SHOWHIST. Those are saved in the DWG rather
than in preferences, so the page says so beside each group and hides them
entirely when no drawing is open.
Changing them also rebuilds the geometry. The SETVAR path never did, which is
why the comment beside LTSCALE's invalidation exists — the same reasoning
applies here, and without it a new isoline count does not appear until some
unrelated edit rebuilds the solid.
Selection cycling joins the Selection page next to the other two selection
modes, since that is what it is.

Two drafting preferences had no proper home. The Drafting Settings dialog
displays the drafting rotation and offers only a Reset button — there was no
way to type an angle short of `SETVAR SNAPANG`. The polar tracking increment
existed in exactly one place: a pop-up hanging off the status-bar pill.
The rotation is a text field over an edit buffer rather than the value
itself, so clearing it to retype does not snap the crosshair to zero on the
way through; the buffer is reseeded whenever the value is restored from
behind it. Angles render without a trailing `.0`, matching how the polar
pop-up has always shown them — same kind of number, same reader.
Snap modes, grid spacing and object snap stay in Drafting Settings, where
they belong; the page links to it.

Zoom direction and factor, whether TEXTEDIT ends after one object, whether
continued dimensions inherit the base dimension's style, which points QDIM
measures from, and which annotative objects pick up a newly set scale. All
six work today; none had a control.
Two of them needed their meaning worked out rather than copied.
ANNOAUTOSCALE stores the mode in the magnitude and on/off in the sign, and
the four modes are not documented anywhere in the app — the command prompt
just says `[-4..4]`. Reading `add_annotation_scale_to_objects` gives them:
1 skips layers that are off, frozen, locked or frozen in the viewport, 2
keeps the locked ones, 3 skips only locked, 4 takes everything. The dropdown
names them instead of showing bare numbers, and choosing Off negates rather
than zeroing, so the mode survives being switched off and back on — which is
the convention the status-bar pill already follows.
The QDIM origin priority had no system variable at all; it could only be
reached through a keyword inside the running command.
Drawing units stay in their own dialog; this page links to it.

Three settings that work, persist, and could only be reached by typing their
name: TEXTFILL, CLIPROMPTLINES and COMMANDLINEFADETIME. The last two govern
how much of the command window is prompt and how long its history lingers —
the kind of thing people fiddle with once and then leave, which is exactly
what a settings dialog is for.
One fix rides along. TEXTFILL is a process-global, so changing it invalidates
the text in every open drawing; the SETVAR path rebuilt only the active tab,
leaving the others rendering the previous setting until an unrelated edit
happened to rebuild them. Both paths now go through
`invalidate_text_everywhere`, so the checkbox and the command cannot disagree.

General had become three unrelated controls: a language picker, a save format
and a file association. The last two move to an Open and Save page, where
they join the two saving preferences that have never had a widget.
Automatic save has worked since the SAVETIME command was added and is
persisted; the only way to change the interval was to type it. Same for the
`.bak` copy from #205 and its ISAVEBAK command. Both are settings people
expect to find in a dialog, and neither was in one.
The page also carries a button through to the Plot dialog. Options holds the
preferences; the plot device, paper and plot styles stay where they already
work well. Note that the modal stack shows one dialog at a time, so the
button replaces Options rather than stacking on it.
Co-Authored-By: Claude Opus 5 <[email protected]>
The dialog laid its pages out as a row of buttons across the top, which is
what AutoCAD does and what fits while there are four of them. The pages this
series adds take it to nine, and the names are translated into 21 languages —
a row of nine German or Russian page names does not fit at any dialog width
worth having.
The rail is now a vertical list down the left, the dialog is 880×620 rather
than 540×560, and the content pane scrolls on its own.
Which page was open is now remembered. With four pages, reopening on General
was a shrug; with nine it means hunting for the one you were last in.
The ribbon's Options tool has existed all along — `ToolDef`, icon and all —
but was marked `#[allow(dead_code)]` and never added to a group, so the
dialog could only be reached by typing OPTIONS or from the start page. It
now sits in Manage ▸ Application, beside About.
No settings change in this commit; it is only the shell the rest needs.

Brings in 54 commits from origin/main: a selection-performance overhaul,
surface thickening, GPU-native wide/tapered stroke rendering, continued
ocs_doc_api evolution, and assorted fixes/polish (block double-click
editing, DWG hatch/database repair, clipboard, collapsible Properties
sections).
Six real conflicts, all where this branch had independently re-applied
a fix upstream later revised or already carried natively:
- src/app/automation.rs, src/app/command_driver.rs: combined both
sides — kept this branch's sketch-constraint/named-parameter loading
on "new"/"open", adopted main's Scene::clear()/material_base_dir and
its newer rebuild_derived_caches() over the older bump_geometry().
Scene::clear() (src/scene/entity.rs) now also resets
sketch_constraints/named_parameters, so every caller gets this for
free instead of each call site repeating it.
- src/io/mod.rs, src/scene/render_graph.rs: adopted main's design
outright (commit 973af87d, authored by Hakan directly) — a large
MINSERT is no longer purged as "corrupt" at load, only its rendering
is bounded, preserving the source data. This branch's own earlier
design (reject at load) predates that revision.
- src/scene/pipeline/mesh_gpu.rs: adopted main's valid_rgba_size()
guard (a real robustness improvement over this branch's version).
- src/snap.rs: replaced wholesale with main's version — this branch's
copy was an explicit verbatim snapshot from an earlier upstream PR
(commit 4c264b8c) with zero constraint-system-specific content, and
main has since evolved it considerably further.
Also removed two now-dead duplicates the merge surfaced without a
conflict marker (both branches had independently fixed the same
things): the OPTIONS/OP command dispatch/autocomplete entries, and
automation.rs's open_finalizes_and_purges_like_the_ui_open_path test
(kept main's version, which covers strictly more: solid_models/
material_base_dir reset on "new").
Full workspace suite passes (812 lib tests + this branch's own 24
constraint/persistence integration tests) except the one pre-existing,
unrelated font-test failure already present on main. Zero clippy
findings in the hand-written merge resolution itself; the ~1,171
warnings clippy reports are pre-existing in the 54 absorbed commits,
not introduced here.

New ConstraintKind variants — Concentric, CenterPoint, Colinear, Midpoint,
Fixed, PointOnCurve, EqualDistance, Symmetric — each built entirely from
existing ocs_gcs (FreeCAD planegcs) primitives, no new solver math needed.
build_constraint now returns Vec<Rc<dyn Constraint>> instead of
Option<Rc<...>>, generalizing the old Coincident-only "needs a second
system-level constraint" special case to every kind that needs one.
Wired into the ribbon (7 new buttons), a new point+pre-selected-entity
command for CenterPoint/Midpoint/PointOnCurve, a new 4-point command for
EqualDistance, and the existing DWG-native class-name mapping (all 8 reuse
the same generic "plain Geometrical node" path already built for
Coincident/Horizontal/etc.). Deliberately not modeled: Normal and
EqualCurvature, which for this app's Line/Circle-only entity model would
just be Perpendicular and Equal wearing different DWG class names.
Also makes DWG-native constraint persistence opt-in (Options > General,
off by default) rather than unconditional: a scope that doesn't yet have
the native graph is only given one when the setting is on, but a scope
that already has one — from an earlier save, or a file that came from
real AutoCAD — keeps getting it resynced regardless of the setting, so
toggling it off never freezes a stale graph in place.

Named parameters (docs/named_parameters_design.md, stages 3-4):
- ParameterTable (src/scene/named_parameters.rs): a document-wide table of
named formulas, each resolved through a shared expression evaluator with
cross-parameter references, cycle detection, and division-by-zero/parse
error reporting. SketchConstraint::driving_param becomes DrivingValue
(Literal | Named) instead of a bare f64, resolved at solve time by
sketch_solve::build_constraint via Scene::named_parameters.
- Persistence (src/scene/named_parameters_persist.rs): same lazy XRecord
model sketch_persist.rs already established, synced around open/save.
Bumps the sketch-constraint XRecord's own format version (1 -> 2) since
DrivingValue's shape doesn't line up with a version-1 blob's bytes.
- PARAMETERS command and its editor (src/ui/window/named_parameters.rs):
add/remove/edit rows, live validation, duplicate-name detection: Apply
defines the table and re-solves every constraint scope with a
named-parameter-driven constraint (command_driver.rs). Distance/Angle
constraint prompts (modules/draw/constrain/value.rs) now accept either a
literal or an existing parameter's name, mirroring how the constraint's
own value prompt already worked.
- Undo scope-down carried over from this project's own established pattern
(constraint-system stage 9): the geometry an Apply moves is one undo
step, but the parameter table edit itself has no undo entry yet — a
documented follow-up, not a silent gap.
UI scale setting (src/app/settings.rs, app/mod.rs, ui/window/options.rs):
a whole-interface scale percentage (50-200%), wired directly into iced's
own per-window scale_factor hook rather than per-panel font-size
plumbing, so it applies immediately to every panel, dialog, and the
ribbon at once. Persisted alongside the existing lineweight-display-scale
setting.
OPTIONS/OP command dispatch (app/commands/view.rs, app/commands/mod.rs):
OPTIONS was registered for autocomplete but had no dispatch arm — the
Start-tab welcome screen's own button was the only way to reach it.
Found live-testing the UI-scale setting, unrelated to that feature
itself. "OP" is AutoCAD's own short alias.
help/: a new self-contained static user-help manual (manual.md as the
authored source, tools/build_help.py splits it into the committed static
HTML pages plus search index) — not yet wired into the application.
64 new/updated tests across the named-parameters and constraint-prompt
changes.

Options → Selection already carried the pick box, the selection-area effect
and the grip visuals. Four settings behind it were finished, persisted and
reachable only by typing a system variable, and one more was a constant.
**Four that only needed a widget.** `SELECTIONEFFECT`, `SELECTIONPREVIEW`,
`PICKADD` and `PICKDRAG` are all wired end to end already. `SELECTIONEFFECT`
was the odd one: the card's own "Restore Defaults" button resets it, so it
could be turned off by a button and only turned back on from the command
line.
`SELECTIONPREVIEW` is a bitmask and gets one checkbox per bit, which is why
`set_preview_bit` exists rather than two inline expressions — the bits are
the thing this change is most able to get backwards.
The `PICKADD` checkbox is worded as AutoCAD words it, "use Shift to add to
selection", which is the *inverse* of the stored flag. That inversion is
commented at both ends; it reads as a bug otherwise.
**`GRIPOBJLIMIT`.** The limit past which a selection gets no grips arrived
with the selection work as a hardcoded 100, matching AutoCAD's default. It is
now a setting, a slider and a system variable, following `PICKBOX`'s path
exactly. AutoCAD's 0 means "no limit", which the old `>` comparison could not
express, so the read now guards on it — with a test, because zero is the one
value that would otherwise suppress every grip instead of allowing all of
them.
The slider covers 0..=1000, where every useful value lives; the sysvar takes
AutoCAD's full 0..=32767, and a larger value set from the command line parks
the handle at the end while the read-out keeps showing the real number.
**`SelectionPrefs`** replaces the `pick_box` parameter rather than adding
three more. `view_window` already took seventeen positional arguments, and
`pick_add` / `pick_drag_rect` are two adjacent `bool`s that would swap
silently at the call site.
**Two fixes found on the way.** `OPTIONS` and `OP` were registered for
autocomplete but never dispatched, so typing either answered "Unknown
command" and the dialog could only be opened from the start page. And the
`SELECTIONPREVIEW` doc comment had its bits the wrong way round — the code
reads `& 1` for the idle rollover and `& 2` for the in-command one, as
AutoCAD does — which would have put the two new checkboxes' labels backwards.
**Not done, deliberately.** `PICKFIRST` and `PICKAUTO` exist but are always
on, with no variable. `PICKSTYLE` is stored in the header and read by nobody
— group expansion decides from the group's own `selectable` flag — so an
"object grouping" checkbox would control nothing. Associative-hatch selection
does not exist as a selection behaviour. Each needs a behaviour change rather
than an exposure.
Of the ten new strings, en-US and el-GR are translated; the other nineteen
locales carry the English text. Composing them from existing keys, the way
el-GR composes the neighbouring labels, only works for one of the ten —
there is no existing key for "limit", "unlimited", "shift", "rectangle" or
"lasso", and "Grips: Objects" as the label of a numeric limit would be worse
than an untranslated string.

Ports FreeCAD's planegcs 2D geometric constraint solver to Rust as a new
crates/ocs_gcs workspace member, and wires it into the document/scene model
as a persistent SketchConstraintSet: Coincident, Horizontal/Vertical,
Parallel/Perpendicular, Equal, Tangent, Distance, Angle and Radius
constraints that re-solve live (including mid-drag, not just on release),
render glyphs and a DOF badge, flag conflicts with a one-click resolver
pill, and round-trip through save/load via an XRecord blob.
Also includes docs/command_reference.md (a statically generated reference
of every registered command and its prompt sequence) and
docs/named_parameters_design.md + docs/backlog.md, which hand off the next
queued feature (a named-parameter/expression table) and consolidate every
deliberate scope-down and open gap found along the way, so a fresh session
has a complete starting point.

Double-click / "Open With" never puts the file on argv — Finder always
delivers it as a kAEOpenDocuments Apple Event instead, which nothing in
this app listened for, so it just showed "cannot open files in this
format" even though the file association itself was registered
correctly.
The standard fix, implementing application:openURLs: on this app's own
NSApplicationDelegate, isn't available here: winit already installs
its own delegate to own window/lifecycle events, NSApplication has
exactly one delegate slot, and winit's class doesn't implement the
open-document method.
This bypasses the delegate protocol and registers directly with the
lower-level Apple Event Manager (AEInstallEventHandler) instead — the
same mechanism AppKit's delegate forwarding is itself built on, and
independent of who owns the delegate. Registration happens on the
iced Subscription's first poll rather than in main() before app::run()
— registering earlier gets silently overwritten by winit's own
NSApplication startup, confirmed by testing against a real `open -a`
rather than assumed from Apple's docs.
This handles a file opened while the app is already running. A cold
launch (app not running yet) needs a different mechanism, in the
following commit.

Switching to a Layout stops the main thread long enough that the
compositor decides the application has stopped responding and offers to
kill it. The switch itself is not the problem — `layout-switch` reports
about 10 ms — it is the frame after it, which rebuilds the whole wire set.
That frame now has a cheap one in front of it. `layout_settling` is set
when the switch takes, and while it holds, the viewport is replaced by a
centered "Preparing layout…" on the canvas background. No shader widget
means no scene primitive, so `prepare` has nothing to do and the frame
costs nothing. A `window::frames` subscription clears the flag, which is
the guarantee this needs: that callback runs once a frame has actually
been presented, so the notice is on screen and the compositor has been
answered before the expensive frame starts.
The deferral is of the *frame*, not the switch. Two callers depend on the
switch having completed when it returns — one calls `fit_all` immediately
after, another compares `current_layout` — so deferring the switch itself
would have broken both.
This restarts the compositor's timer immediately before the slow frame and
replaces a stale window with something that says what is happening. It
does not make the slow frame fast: if the rebuild still exceeds the
compositor's timeout the dialog can return, and the durable fix is the
2 s `memo_miss` behind it, which is a separate change.
Only `en-US` is validated against at build time; Greek is filled in too
since it is in use here, and the rest fall back until translated.
