Entity pick → text input subcommands:
C / CLOSE → set closed flag
O / OPEN → clear closed flag
W <value> → set uniform width on LwPolyline vertices
X / EXIT → cancel
Command stays active after each op (CmdResult::PeditOp) for multiple edits.
Supports LwPolyline and Polyline2D.

Status bar: shows "N VP" pill (with tooltip) when in a paper layout that has
user viewports (id > 1). New Scene::viewport_count() method.
REVCLOUD: closed LwPolyline with arc bumps (bulge = 0.5) along each edge.
Click polygon corners, Enter to close into a revision cloud shape.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Pick polygon corners, Enter to close. Each edge is subdivided into arc
bumps (bulge = 0.5 ≈ 53° arcs). Result is a closed LwPolyline.
Arc bump length defaults to 1.0 drawing units.

wires_for_block() now looks up the SortEntitiesTable for the current block.
When found, wires are sorted by sort_handle.value() so DRAWORDER F/B results
are immediately visible in the viewport (not just written to DXF).
Entities not in the sort table default to u64::MAX/2 (middle of draw order).

Options via text input after entity pick:
DE <delta> — extend by delta (negative trims)
TO <total> — set absolute total length / arc length
P <percent> — scale by percentage
<number> — plain number treated as DE delta
Closest end to pick point is modified. Uses CmdResult::LengthenEntity.

Selection-gathering mode: select objects, press Enter to apply.
- Lines: checks collinearity + no-gap, merges into single line span
- Arcs: checks same center/radius + contiguous angles, merges to Arc or Circle
- Uses CmdResult::JoinEntities; geometry computed in cmd_result from document

3-step interactive flow:
1. Entity pick (first break point recorded at click location)
2. Optional first point refinement
3. Second break point → CmdResult::BreakEntity applied in cmd_result
Geometry:
- Line: project p1/p2 onto line parameter space → two line fragments
- Arc: project p1/p2 to arc angles → trim CCW from p1 to p2
- Circle: same as Arc, converts Circle → Arc
- LwPolyline: nearest-vertex split → two polyline fragments

Add three classic CAD measurement commands:
- DIST (DI): two-point pick → distance, angle, delta XYZ
- ID: one-point pick → coordinates
- AREA: multi-point polygon pick (Enter to close) → area + perimeter
New CmdResult::Measurement(String) variant ends active command and
prints result to command line without modifying the document.

- properties.rs: inject 'UCS Name' Choice property for viewports when
document.ucss is non-empty; resolves current handle to display name
- update.rs: intercept PropGeomChoiceChanged for 'vp_ucs_name'; clones
UCS origin/x_axis/y_axis into viewport and sets ucs_handle — no
trait signature change required

- viewport_content_wires(): conditional perspective divide using
camera_dist = view_height * lens_length / 24.0 (35mm-film equiv.);
points behind the camera are mapped to NaN for safe clipping
- viewport.rs: expose lens_length, ucs_per_viewport, ucs_origin,
ucs_x_axis, ucs_y_axis as editable properties; handle all new
fields in apply_geom_prop()

PageSetup panel:
- Paper size presets (A4/A3/A2/A1/A0 portrait+landscape, Letter)
- Plot area selector: Layout vs Extents
- Center-on-page toggle
- Plot offset X/Y fields
- Rotation picker: 0° / 90° / 180° / 270°
PlotSettings (acadrust object):

locked viewports now reject pan/zoom inputs entirely
- Add perspective, render_mode, shade_plot_mode, hide_plot, ucs_icon_visible
fields to the viewport property panel with appropriate pickers/toggles
- Add VPORTS command: lists all user viewports in the current layout
(id, size, position, scale, on/locked state) in the command line
- Add VPLAYER command: per-viewport layer freeze/thaw from the command line
(F <layer> to freeze, T <layer> to thaw, Enter to exit)
- Add CmdResult::VpLayerUpdate variant and its handler in apply_cmd_result

Snap is now suppressed (both cursor indicator and coordinate snapping)
when a command is in entity-pick mode (needs_entity_pick) or
selection-gathering mode (is_selection_gathering), and restored
automatically when the mode ends.

line_weight_px was multiplied by the viewport scale factor, making lines
near-invisible at small scales (e.g. 1:100) and overly thick at large
scales (e.g. 5:1). Line weights represent physical pen widths on the
plotted sheet and must be constant regardless of viewport scale.

The preview rectangle used c1.y (constant) for all four corners and
pt.z for Z instead of c1.z. Corners 3 and 4 now correctly use pt.y
(varying Y) and the constant c1.z, producing a proper XY-plane rectangle.
Fixed in both layout/mview.rs and manage/mview.rs.

Selection, snapping and editing are now mode-aware:
PSPACE (paper layout, no active viewport)
- Only paper-space entities (viewport borders, title blocks, etc.) are
hit-testable and selectable. Viewport content wires are invisible to
the interaction layer.
- Drawing commands add entities to the paper-space layout block so
annotations/title blocks land on the sheet, not in model space.
MSPACE (active viewport entered)
- Only model-space entities visible through the active viewport are
hit-testable. Other viewports' content and paper entities are ignored.
- Drawing commands add entities to model space (correct DXF block).
- Snap results from projected viewport-content wires are converted from
paper-space back to model-space via paper_to_model so that placed
coordinates and command previews are consistent.
Entering/exiting MSPACE clears the current selection so no stale
cross-space selection is carried over.
Implementation:
- Scene::hit_test_wires() returns mode-filtered wires for all
hit-tests, snaps, and selections (entity_wires() still returns
everything for rendering and PDF export).
- viewport_content_wires() gains an Option<Handle> filter to render
only the active viewport's content for MSPACE hit-testing.
- Scene::add_entity() routes to the paper-layout block or model-space
block depending on current_layout / active_viewport.

Four bugs prevented viewports from working like AutoCAD model-space windows:
1. Dead-code double-click block: `!is_down2` was always false because
`is_down2 = sel.left_down` is captured while the button is still held
(before the selection block clears it). Changed to `is_down` so the
double-click handler actually fires.
2. Inverted pan direction: pan_active_viewport used `-=` on the delta
returned by screen_delta_to_world, which is the same delta that cam.pan
*adds* to its target — causing reversed drag. Changed to `+=`.
3. Zoom not cursor-centered: zoom_active_viewport now accepts an optional
paper-space cursor position and adjusts view_target so the model point
under the cursor stays fixed (same as cam.zoom_about_point).
4. ESC did not exit MSPACE: CommandEscape now calls ExitViewport when
active_viewport is set and no command is running.
Also added MS/MSPACE and PSPACE command aliases, and MspaceCommand /
PspaceCommand messages so MS auto-enters the first viewport.

CadDocument::new() inserts default Layout1; DXF/DWG readers then add
the file's own Layout1 on top, producing duplicate tabs with the same
name but different handles. layout_names() now deduplicates by name,
preferring the entry with a non-null block_record (the real layout from
the file).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Root cause: the DXF reader never reads group code 340 (block_record
handle) inside LAYOUT objects, so layout.block_record stays Handle::NULL
after opening any DXF file. This caused current_layout_block_handle()
to return NULL, which made belongs_to_visible_block() return true for
every entity — all entities appeared in all layouts simultaneously.
Fix in current_layout_block_handle() — three-tier lookup:
1. Layout.block_record (non-null) — works for DWG files.
2. Conventional DXF name ("*Model_Space", "*Paper_Space", …) derived
from the layout's tab_order — works for standard DXF exporters.
3. Position-based fallback: sort paper-space block records and paper
layouts independently, then match by index — handles exporters that
set tab_order = 0 for all layouts.
Apply the same two-tier lookup to model_space_block_handle().

Paper limits:
- Change A4 fallback from 12×9 to 297×210 mm in paper_limits()
Context menu:
- Translate layout context menu labels to English (Rename / Delete)
Viewport clipping:
- Replace AABB-only culling with proper Cohen-Sutherland line clipping
in viewport_content_wires(); each projected segment is now clipped at
the exact viewport boundary instead of being included or discarded whole
- Add cs_clip() and clip_polyline_to_rect() free functions in scene/mod.rs
Frozen layers per-viewport UI:
- Inject a "Frozen Layers" EditText property in the Properties panel for
viewport entities (layer names resolved from handles at display time)
- Handle "frozen_layers" in PropGeomCommit: parse comma-separated names,
resolve to layer handles, update vp.frozen_layers in-place
PDF export improvements:
- Add offset_x/offset_y params to export_pdf() for model-space normalization:
coordinates are shifted so the drawing origin maps to the page origin
- Model space export computes extents via model_space_extents() (now public)
and adds a 5 % margin; falls back to A4 landscape for empty drawings
- Skip __paper_boundary__ wire in PDF (white background covers it)
- Map yellow (active viewport border) → black and cyan (vp border) → dark
blue for print-friendly output

- Add printpdf 0.9.1 dependency for native PDF generation.
- New src/io/pdf_export.rs: converts paper-space WireModels to a PDF
page (per-wire stroke color, line weight in Pt, NaN-split segments).
White/near-white colors are inverted to black for print output.
- Add PlotExport / PlotExportPath messages: opens a save-file dialog
and writes a .pdf next to the drawing file.
- Add PageSetupOpen/Close/WidthEdit/HeightEdit/Commit messages: a
centered modal panel lets the user enter paper width and height (mm);
on commit the Layout object's min/max_limits are updated in-place.
- Register PRINT / PLOT / EXPORT and PAGESETUP (PS) commands in
dispatch_command; fix MVIEW error message to English.
- Layout ribbon gains a "Plot" group with Page Setup and Export PDF
ribbon buttons.

- Add model_space_extents() to Scene: collects key_vertices from all
model-space entities to compute an AABB.
- Add auto_fit_viewport() to Scene: sets view_target to model centroid
and derives custom_scale / view_height so the content fits the new
viewport with a 10% margin.
- Call auto_fit_viewport() in commit_entity() after a viewport is added
to a paper-space layout, so newly placed viewports immediately show
model-space content at a sensible scale.
- Scale line_weight_px by the viewport scale factor when projecting
model-space wires into paper space, so dimension arrows and annotation
lines appear at the correct visual thickness.
