Modern DWG (R2000+) has no file slot for OSMODE — reading a file left
the header at 0, and adopt_header_sysvars wiped the user's running snap
set on every open. Persist the set (as an $OSMODE-style bitmask) in
settings.json, save it on every snap toggle, and only let a file
override it when it actually carries a nonzero mask (R13/R14 DWG, DXF).

Add SelectThenValueCommand (gather selection, then one value) and convert:
- SelectThenValueCommand: HYPERLINK (url), ARCTEXT (text), TEXTFIT (width),
SCALETEXT (factor), TCOUNT (start), TEXTMASK (Enter to apply).
- SelectThenKeywordCommand: JUSTIFYTEXT (Left/Center/Right/Middle/Aligned/Fit),
TCASE (Upper/Lower/Sentence/Title).
Each bare form gathers a selection when none is set, prompts, and delegates to
the inline handler. OBJECTSCALE already opens its dialog; TABLE CELL takes three
values (row/col/text) and stays typeable — TABLE bare already builds a table
interactively.
Add SelectThenKeywordCommand: if nothing is selected it first gathers a
selection (Enter confirms, following the ALIGN contract), then shows the
sub-verbs as buttons like KeywordCommand and dispatches `<name> <verb>
[value]` to the inline handler, which reads the still-selected set.
Convert CHPROP, ADJUST, XDATA, UNDERLAY and DRAWORDER. Verbs the single-value
generic can't express keep working by typing the full line: XDATA SET
<app> <value> and DRAWORDER Above/Under <handle> (a reference pick) are left
off the buttons; CHPROP/ADJUST/UNDERLAY are fully covered.
Verified end to end: SELECTALL then `CHPROP LAYER <name>` moves the selected
entity to that layer through the stepped front-end.
Convert the remaining bucket-B commands to prompt step by step instead of
requiring arguments or printing usage:
- KeywordCommand (buttons): VIEW, LINETYPE, SCALELISTEDIT, UCSICON, VSCURRENT.
- ValuePromptCommand (one value): LAYDEL (layer), ATTSYNC (block).
- TwoValuePromptCommand (new; two values): LAYMRG (source + target),
SETVAR (variable + value, blank second reads).
Each bare form now starts the stepped front-end and delegates to the existing
inline handler; the argument form is kept and is the dispatch target. The
direct visual-style shortcuts (HIDDENLINE / XRAY / …) and UCSICON's argument
form are untouched.
COUNT is intentionally left alone: bare COUNT already reports the tally (a
useful inquiry action, not a usage line), so prompting would only add friction.
Bare CLAYER / CDIMSTY / COLOR / LWDISPLAY / ISAVEBAK / FILEASSOC /
SAVETIME / ANNOSCALE printed the current value or a usage line and
stopped; only the fully-typed `NAME <value>` form set anything. Route the
bare form through ValuePromptCommand (the pattern LTSCALE / PDMODE / PDSIZE
already use): it prompts for the value and re-dispatches `NAME <value>` to
the existing inline handler, so the set/get logic stays in one place. The
bare-Enter getter is preserved — ValuePromptCommand dispatches `NAME `,
which the argument arm reports the current value for (added that empty
case to ISAVEBAK / FILEASSOC / SAVETIME, which previously errored on it).
COLOR keeps BYLAYER as an immediate shortcut rather than a prompt.
USERR / USERI are left as-is: they take two inputs (register 1-5 + value),
so they need a two-step command rather than the single-value prompt.
Bare RENAME printed a usage line and did nothing; only the fully-typed
`RENAME <type> <old> <new>` form worked. Add a stepped front-end
(RenameCommand) that prompts for the object type — as clickable buttons
(Layer, Text style, Dim style, Linetype, UCS, View) — then the current
name, then the new name, and dispatches to the existing inline handler.
The rename logic stays in one place; the argument form is kept and is also
the front-end's dispatch target. BLOCK is left off the buttons because the
inline handler does not implement it.
Ortho and the running object-snap set were app-global (settings.txt only) and
Isolate/Hide was a session-only view state, so none survived save/reopen and
none were per-drawing. Bind all three to the file like AutoCAD:
- Ortho -> header.ortho_mode ($ORTHOMODE); running OSNAP <-> header
.object_snap_mode ($OSMODE bitmask) via a new SnapType<->bit map in settings
(osmode_from_snaps / snaps_from_osmode, round-trip tested). The header is the
per-drawing store, live state mirrors the active drawing: adopt header->live
on open and tab-switch, stamp live->header on save and when leaving a tab, a
fresh drawing inherits the current values, and SETVAR ORTHOMODE/OSMODE now
also update the live state. settings.txt stays as the boot/new-drawing
default; the per-file header overrides it on open.
- Isolate/Hide now set each entity's persisted invisible flag (DXF code 60,
which acadrust round-trips in DXF and DWG) in addition to the session set;
End Isolation clears it. The set is reseeded from invisible entities on load
and after undo/redo, the commands are undoable and mark the tab dirty. The
renderer already skipped invisible entities, so no render change was needed.

TEXTFILL 1 (default) fills TrueType text; TEXTFILL 0 draws it hollow
(outline only). Settable directly or via SETVAR, 0/1 or ON/OFF. SHX/LFF
stroke fonts are unaffected.
Reuses the existing stroke-SDF path: bake_glyph treats a TTF glyph as a
stroke (outline) field instead of a signed fill field when TEXTFILL is
off. Toggling resets the glyph atlas and re-tessellates text so quads
pick up the re-baked tiles. Persisted in user settings.

Typing a bare system-variable name (MIRRTEXT, FILLMODE, LTSCALE, …) now
echoes the current value and prompts "Enter new value for <NAME> <cur>:",
capturing the next command-line entry as the new value — Enter keeps the
current one, Escape cancels. The single-line "MIRRTEXT 1" form still works.
Mirrors the awaiting_vports pattern: a pending_setvar field on the app,
consumed at the top of on_command_submit.

Color/linetype/lineweight/layer are baked into the cached wire geometry
at tessellation time, so a property edit only repaints if the handler
bumps the geometry epoch. The color path did; several siblings only set
tabs.dirty (a save flag) and never re-tessellated, leaving the viewport
showing the stale look.
Route every handle-based edit through invalidate_property_targets
(mark dirty + recolor meshes + bump geometry), and full-bump the
name-based LAYER COLOR change:
- ribbon layer / linetype / lineweight dropdowns applied to a selection
- CHPROP (color/linetype/ltscale/transparency/layer)
- LAYMATCH (MatchEntityLayer)
- LAYER COLOR <name> <aci>

PURGE removed unused layers/styles/linetypes from the document but never
refreshed the layer panel + ribbon caches, so the removed definitions
stayed visible in the UI (issue 228). It also never purged blocks.
- call refresh_layer_panel() after a purge so panel/dropdowns update
- purge unused block definitions (no INSERT/Dimension reference), skipping
anonymous, layout, and xref records; drop their member entities too
- add PURGE BLOCKS sub-arg; bare PURGE / PURGE ALL now include blocks
- report a per-type breakdown in the result message

A periodic subscription (every SAVETIME minutes — default 10, 0 disables)
writes a <name>.sv$ recovery copy of each dirty, already-saved drawing at its
own DWG version. Non-destructive: it never touches the original file or the
dirty flag, and skips unsaved (path-less) tabs. The SAVETIME command
sets/queries the interval and persists it. Recovery files (.sv$ and .bak) open
through the normal Open dialog — the loader detects DWG vs DXF from the leading
magic bytes, and a "Backup / Autosave" filter lists them.

`FILEASSOC 1` (re)registers the app as a .dwg/.dxf/.bak handler; `FILEASSOC 0`
unregisters it (removes the .desktop + CAD mime package on Linux, the per-user
registry keys on Windows); bare `FILEASSOC` reports the current state. The
choice persists (file_assoc_enabled) and gates the every-launch
re-registration, so turning it off stays off across restarts.

- Save: overwriting an existing file first copies it to a sibling <name>.bak
(default on; toggle with the ISAVEBAK command, persisted in settings).
- Open: .bak is a first-class type — the Open dialog lists it and the loader
detects DWG vs DXF from the file's leading magic bytes (the extension hides
the real format).
- File association registers .bak too, every launch (so users who associated
earlier get it automatically): Windows via the registry; Linux via a
high-priority shared-mime-info magic that resolves DWG/DXF content under the
.bak extension, with the generic *.bak glob claimed only once the app is the
default DWG handler — so it never hijacks other apps' backups.

Integrate a large batch of standard CAD commands and fix several
name/behaviour mismatches, with no product references in code.
3D solids (reusing the truck B-rep pipeline):
- SLICE, INTERFERE, PRESSPULL, POLYSOLID, PYRAMID, SECTION
- 3DROTATE, 3DMIRROR, 3DALIGN (cached-solid transforms)
Annotation / text:
- ARCTEXT, SPLINEFIT (Catmull-Rom to Bezier), DIMJOGGED, OBJECTSCALE
(XData markers honoured by the existing geometry-gen / tessellator)
Blocks / misc:
- NCOPY (block-content extraction via explode_entity)
- OPTIONS, SYNCPVIEWPORTS, THICKEN, plus earlier toggles, aliases,
system variables, and layer/style/view commands
POINTCLOUD/RECAP and UNDERLAYLAYERS/UOSNAP are intentionally left out:
they require a proprietary binary / PDF-layer parser, a GPU point
renderer, and real test files.

Broad pass over the command set: integrate missing commands, wire
previously-unreachable ribbon/menu buttons, and correct name/behaviour
mismatches. Every UI command token now resolves (real handler where the
infrastructure exists, an honest "not yet implemented" status otherwise).
New commands:
- Draw: 3DPOLY, 2D solid (SO/SOLID2D), HELIX, TRACE, SKETCH, DIMCENTER
(DCE/CENTERMARK)
- Modify/inquiry: REVERSE, MEASUREGEOM (MEA), DBLIST
- Data/manage: BASE, OVERKILL (exact-duplicate removal), AUDIT (read-only
integrity report), SETVAR (system-variable get/set), SCRIPT (.scr runner),
FINDNONPURGEABLE
Behaviour fixes:
- LINE and SPLINE gain Close/Undo; AREA computes area/perimeter in f64
(correct at large coordinates)
- ATTEDIT/ATE unified so the alias and the ribbon button open the
interactive editor; -ATTEDIT is the command-line form
- Linear/aligned/radius/diameter dimensions gain a text override (Text) and
text angle (Angle) option
- INSERT gains Scale/Rotate options; COPY gains an Array option
- LINETYPE SET sets the current entity linetype; SETBYLAYER resets overrides
- UNDO accepts a step count
Integrations: standard dimension/block aliases (DLI/DRA/DAN, BMAKE,
EXPORTPDF, DDIM), drafting-aid and screen toggles (GRID/SNAP/POLAR/OSNAP/
DSETTINGS/CLEANSCREEN/QUICKPROPERTIES), viewport tiling
(CASCADE/HORIZONTAL/VERTICAL/VPJOIN), and customization entry points
(CUI/ALIASEDIT).

Break up the four giant files (~29k lines total) into focused submodule
directories, one concern per file. Pure mechanical moves — behavior is
unchanged.
- app/update.rs (9650) -> app/update/{mod,viewport,command,style,file,
dynamic,dialog,util}. The 384-arm update_inner match stays in mod.rs
with thin delegating arms; the 66 fattest arm bodies move to topic
methods. Arm set preserved exactly (384 -> 384).
- scene/mod.rs (9017) -> scene/{mod,entity,tess,hittest,layout,paper,
mspace,project,selection,modify,group_layer,preview}. The impl Scene
body is split across files via inherent-impl-per-file; struct, ctor,
fields and load-time helpers stay in the root. fn count 123 -> 123.
- app/commands.rs (6082) -> app/commands/* grouped by command family.
The 233-arm dispatch match becomes source-ordered per-family
dispatch_* handlers, preserving first-match precedence (233 -> 233).
- app/view.rs (4686) -> app/view/{mod,overlay,modal,viewcube,controls}.
Largest file drops from 9650 to 3343. Builds clean; app launches and
loads plugins with no panic.
