Hakan SevenandClaude Opus 5 6cbec232bb feat(units): read back every form the drawing writes
The readout learned to write lengths as 5'-6 1/2" and angles as
N 45d0'0" E, but typed input was still a bare parse::<f64>() — a
coordinate could be displayed and not entered. Give the formatters
their inverses.

parse_length takes feet and inches separated by a dash, a space, or
nothing, with the closing quote optional, and whole-plus-fraction in
any of those forms: 5', 60", 5'-9", 5'9-1/2, 9-1/2, 1/2. A leading
minus is a sign; the one inside 5'-9" is a separator, since after feet
there is nothing left to subtract from.

parse_angle reads the mark that says which convention an angle is in —
g for grads, r for radians, d/'/" for degrees-minutes-seconds, compass
letters for a surveyor's bearing — and reads a bare number in whichever
convention the drawing is set to.

ANGBASE and ANGDIR now apply, but only where they mean something. Which
way a thing points is measured from the drawing's zero and runs the way
it says; how wide an arc opens is the same number whatever zero is
counted from. format_direction and parse_direction are the pair for
directions, and the polar readout and polar input both go through them,
so the bearing shown is the bearing accepted. format_angle stays for
sizes, where applying a base angle would corrupt the value.

The command prompts follow the same rule, each classified rather than
swept: OFFSET distance, FILLET radius, CHAMFER distances, ARRAY and
MINSERT spacing, TRACE width, HELIX, and EXTRUDE height read lengths;
the four dimension text-rotation prompts, ARRAY's total angle and
INSERT's rotation read angles. MLINE's scale and INSERT's scale factor
are left alone — a multiplier has no unit to be written in. INSERT read
both through one parse; they are now separate.

The typed variants also take a decimal comma, which a single-value
prompt has no other use for. parse_length itself does not: inside a
coordinate the comma separates the axes.

Hakan SevenandClaude Opus 5 7c8271c716 fix(icon): draw every icon from the logo file
Two places still showed the old mark after the logo was redrawn.

The window icon was built by drawing the letterforms stroke by stroke in
code, background colour and all, which made it the one icon in the
application not coming from assets/logo.svg. It now rasterises that file,
fitted to the square without distorting whatever aspect the logo has. It
returns nothing when the logo cannot be rendered, so the window falls back
to the platform default instead of to something invented here -- which is
how it ended up stale in the first place.

The icon installed into the icon theme was only ever written from inside
the desktop-entry write, behind that write's own "nothing changed" early
return. The entry's text does not change when the logo does, so once it
had been written the icon was never refreshed again. The two change for
different reasons; the icon is now checked first and on its own terms. It
already compares bytes, so an unchanged logo still costs only a read.

Worth knowing on Wayland: the compositor ignores the window icon entirely
and takes the dock icon from the desktop entry, so there the installed
theme file is the only one that matters -- and it refreshes when the file
associations are next set up, not at launch.

Hakan SevenandClaude Opus 4.8 0e61836e91 fix(properties): name AEC / proxy objects instead of "Unknown"
Selecting a proxy object we render from its cached graphics (an AEC
Wall/Door/Window and the like) showed "Unknown" as its type. The entity
now carries its real DXF class name from the CLASSES section (acadrust
bump), so surface it: ui_name_or_class title-cases the class ("AEC_WALL"
→ "Aec Wall") for the properties Type row and the status-bar label, and
still says "Unknown" only when the class truly can't be named.

Hakan SevenandClaude Fable 5 51f07f1208 feat(snap): Shift hard axis lock during point picks (#312)
Holding Shift while a command asks for a point captures the nearest
polar increment (or ortho axis, UCS-aware) from the rubber-band base
toward the cursor and pins the pick to that ray. Every candidate —
osnap hits included — projects onto the locked direction, so a snap far
off-axis contributes only its along-axis component; the click commits
exactly what the preview shows. The direction stays fixed while Shift
is held and drops the moment it releases. Grip drags get the same lock
from the grip origin.

Guards: engages only when the active command wants a point — never
during entity picks (Shift there is the TRIM/EXTEND swap), tangent
picks, selection gathering or window-corner picks.

Closes #312

Hakan SevenandClaude Opus 4.8 1cfb856224 refactor(dwg): use the first-class SectionSymbol and ViewBorder entities
Section marks and drawing-view borders are now real acadrust entity
types instead of Unknown-with-extras, so the renderer dispatches on the
variant directly, the arrow-direction resolver reads the active viewport
off the ViewBorder entity, and selection / properties show "Section
Symbol" and "View Border" instead of "Unknown". View borders are
non-plotting and tessellate to nothing; both count toward the lossy
Save-As warning since they round-trip via their raw records.

Bumps acadrust for the entity promotion.

Lights, camera views and the geographic-location marker had no on-screen

- Lights render through a new EntityType::Light: a cone/flashlight for spot
  lights, a wire sphere for point lights, a sun for distant lights, sized in
  screen space (fixed-world fallback).
- Camera views (perspective VIEW records) and the GEODATA "daisy" marker are
  synthesized into the model-space resident wire set from the document, since
  they are not entities.

Hakan SevenandClaude Opus 4.8 57710eec2b fix(precision): keep typed coordinates exact in f64 (#311)
Typed values were quantized to the f32 grid before reaching the
entity (e.g. a length of 2000.8 committed as 2000.8020), worsening
with magnitude. The interaction point layer was all glam::Vec3 (f32).

Two-layer fix:

1. Coordinate backbone -> f64. last_point, last_cursor_world,
   dyn_anchor, dyn_ref become DVec3; UcsXform transforms, parse_coord,
   the ucs helper fns, dyn_resolve_point, the OTRACK typed-distance
   paths, command-line coordinate entry and the coordinate readout all
   compute in f64. Screen/GPU/alignment stays f32 (snap engine, render
   geometry, projection, UCS-icon/viewcube drawing) with casts only at
   those boundaries.

2. Per-command committed storage -> DVec3. on_point already received a
   DVec3, but many command impls narrowed it back to f32 (let pt =
   pt.as_vec3(); Vec<Vec3> fields) and re-widened at build, quantizing
   the committed coordinate. Migrated PLINE, SPLINE, MLINE, LENGTHEN,
   INSERT, 3D primitives, every dimension/leader/mleader, ray, revcloud,
   wipeout, attdef, table, tolerance, array center, mview, plot_window,
   plus the QDIM_PLACE handler and qdim_collect_points. Preview,
   hit-test and rubber-band paths keep f32 at the boundary.

Hatch manual boundaries are left for a follow-up: HatchModel.boundary
is structurally Arc<Vec<[f32;2]>> and needs a model-level widen.

Hakan SevenandClaude Opus 4.8 c249a99d4c fix(clipboard): paste anchor at bounding-box lower-left, not center (#285)
COPYCLIP/CUTCLIP used the mean of each entity's bounding-box centre as the
paste anchor. Standard clipboard behaviour puts the lower-left corner of the
box enclosing all copied items under the cursor. Union each entity's bbox min
corner instead, and rename clipboard_centroid -> clipboard_base (COPYBASE also
stores a picked point there, so "centroid" was inaccurate).

sLuCHa 56835791af perf(clipboard): derive the paste anchor from bounding boxes
COPYCLIP/CUTCLIP computed the clipboard anchor by tessellating every
selected entity and averaging all wire vertices — O(total geometry),
~250 ms when copying a whole drawing. The anchor only fixes which point
of the selection sits under the cursor at paste, so the mean of each
entity's bounding-box centre is an equally valid, far cheaper origin.

Hakan SevenandClaude Opus 4.8 60d4712179 fix(paste): UTM-precise paste/block base via f64 centroid
entities_centroid summed the f32 points (double-single HIGH half) alone, so
at UTM scale (~5.7e6) it both quantized each term ~0.5 m and lost low bits
across the running total — drifting the paste base and PASTEBLOCK's block
base metres off, which placed the wrapped block at the wrong spot/scale.

It now reconstructs each vertex's absolute f64 from points + points_low and
accumulates in f64. clipboard_centroid is DVec3; the PASTECLIP commit delta
is fully f64; define_block_from_owned_entities takes an f64 base so the
block-local fold (Translate(-base)) stays precise. The interactive ghost
anchors (PasteCommand, InsertBlockCommand) still take the f32 cast — display
only; the committed geometry is f64.

Hakan SevenandClaude Opus 4.7 96aaf2a293 feat(snap,pick): eye-relative CPU projection — drop full view_proj at UTM
Route the remaining absolute-coordinate CPU projection through the
relative-to-eye path so it no longer multiplies by a view_proj matrix
carrying a ~1e7 translation (which cancels catastrophically in f32 after
world_offset removal):
- camera pick_on_plane / pick_on_target_plane delegate to
  unproject_on_plane_f64 (rotation-only inverse + f64 eye)
- snapper (world_to_screen), hit_test (click_hit / mesh / hatch), the
  scene mesh/solid hit methods, grid + UCS axes, and polar_constrain_near
  all take view_rot + eye and project relative-to-eye
- compute_grid_step measures the per-unit scale via the rotation-only
  matrix (no eye term needed)

view_proj remains only for conservative CPU frustum-cull / scissor and the
screen-space viewcube / UCS-icon directions. NOTE: SnapResult.world and
the command-point chain are still Vec3 (f32) — a ~0.5 m quantization at
extreme UTM zoom remains; the command layer goes f64 next.

Hakan SevenandClaude Opus 4.8 2509396ba0 fix(ucs): object snap tracking rays follow the active UCS
OTRACK alignment rays (0°/90° and polar steps, plus the polar pencil from
the last point) were built along world X/Y. They now rotate with the
active UCS via a Mat4 passed into otrack_snap (scene.viewcube_ucs_mat() —
the UCS in model space, identity in paper), so tracking lines and the
intersection lock align to the user's coordinate system like ortho,
polar, and the grid. sync_ucs_to_scene now reuses UcsXform::rotation_mat.

Hakan SevenandClaude Opus 4.8 b676874a6f feat(ucs): dynamic-input deltas and angle in the active UCS
The on-canvas dynamic-input boxes measured relative X/Y deltas and the
polar angle in world axes. They now read in the active UCS plane (via
UcsXform::vec_to_ucs on the offset-invariant delta), matching the UCS
ortho/polar constraints and coordinate readout. Identity UCS reproduces
the world-frame values; absolute first-point fields are unchanged.

Ortho and polar drawing constraints snapped to world X/Y; under an active
UCS they now snap to the UCS axes, routed through the shared UcsXform

Hakan SevenandClaude Opus 4.8 4aa1e90dcf feat(ucs): central WCS↔UCS converter; adopt file UCS, drive readout + icon
Introduce one bridge between WCS (how geometry and the file are stored)
and the active UCS (the coordinate system the user works in), so every
UCS-aware system routes through it instead of re-deriving axis math.

- UcsXform (app/helpers.rs): the converter — to_wcs/to_ucs (points),
  vec_to_wcs/vec_to_ucs (directions), axes(), is_identity(). Orthonormal
  axes, so the inverse is the transpose. The old ucs_to_wcs / ucs_rotate_vec
  free fns now delegate to it (one implementation).
- DocumentTab::ucs_xform() builds it from the tab's active_ucs (None = WCS).
- DocumentTab::adopt_active_ucs_from_header() loads the document's saved
  current UCS (header model-space UCS) into active_ucs on open, so the file's
  coordinate system is live immediately; called from both load paths.
- Status-bar coordinate readout reports the cursor in the active UCS.
- UCS icon tripod projects the active UCS axes, so it rotates to the UCS
  instead of always showing world X/Y/Z.

First slice of routing the app's coordinate systems through the converter;
input/picking, grid, ViewCube, and the remaining readouts follow.

Gate target-specific code so neither build warns about the other's items:
native-only helpers (view, window icon, file dialogs, file association, plugin
host/guard/registry, self-update) are cfg'd to non-wasm; the wasm-only font
fallback (script_of / cjk_lang / request) is cfg'd to wasm. Drop an unused mut,
allow the few genuinely-conditional dead items (mesh_click_hit, GPU layout
helpers, parity stubs), and gate the embedded PlotSettings-unrelated dead
constants. Both targets now build clean (only the unavoidable nom/quick-xml
future-incompat dependency notice remains).

Hakan SevenandClaude Opus 4.8 47f74a9b98 feat(clipboard): paste menu with paste-to-original and paste-as-block
Turn the ribbon Clipboard "Paste" button into a dropdown:
- Paste — existing pick-a-point paste.
- Paste to Original Coordinates — drops the clipboard at its source
  coordinates with no prompt.
- Paste as Block — wraps the clipboard contents in a new block definition
  and starts an interactive insert (prompts for the drop point, with the
  geometry rubber-banding under the cursor).

Also fixes two bugs the new commands exposed:
- entities_centroid summed the NaN separator points wire models carry,
  so the paste base point came out NaN; non-finite points are now
  skipped. A NaN base previously froze block tessellation outright.
- PASTEORIG added clipboard entities with their original handles
  (duplicates on same-document paste); it now goes through
  add_entity_clone and merges referenced records like the other pastes.

ACAD_SURFACE entities now load and render. Their NURBS faces are

control net and knot vectors, then sampling its parametric grid — reusing the
same NURBS kernel the Model tab already builds on. Analytic faces
(plane/cone/sphere/torus) continue through the existing tessellator.

- New spline_tess.rs: parse the ACIS `nubs` block (degrees, knots with the
  clamped end-multiplicity fix, control grid) into a truck BSplineSurface and
  mesh it.
- tessellate_surface + Surface wired through the mesh-build, fallback-wire,
  and entity-classification paths.
- Bump acadrust to the commit that adds the Surface entity.

Hakan SevenandClaude Opus 4.8 3c97111d8f fix(polar): only snap near a polar ray (#70)
POLAR locked the cursor to the nearest angle everywhere, so it could
never point between angles. Snap only when the cursor is within the snap
aperture (in screen pixels) of a polar ray; otherwise leave it free, so
POLAR behaves as if off when pointing away from every angle. The polar
guide line now shows only while actually snapped.

Koordinat girişi artık göreli/mutlak ayrımını destekliyor:

- `#x,y[,z]` → her zaman mutlak (DYN durumundan bağımsız)

İlk noktada referans olmadığından göreli giriş mutlağa düşer. Çözülen

Two near-identical match-on-EntityType tables lived far apart:
scene/properties.rs::entity_type_name returned mixed-case UI labels;
app/commands.rs::entity_type_name returned uppercase DXF record names.
Both enumerated ~30 variants; adding a new entity meant remembering to
touch two files in two crates' worth of source layout.

Move both into a single entities/names.rs as `ui_name()` and
`dxf_name()`. Adjacent so a new variant gets both labels added at once;
function names make the intended audience explicit at the callsite.

scene/properties.rs and app/commands.rs each lose their local match
plus one re-export, gaining a `crate::entities::names::*` call.
