OFFSET's Erase and Layer keywords open their Yes/No and Current/Source
prompts (remembered in OFFSETERASE/OFFSETLAYER and shown in the current
settings line); Multiple keeps offsetting the newest copy until Enter and
Undo takes back the last offset. The JSON form takes `erase` and `layer`.
MOVE and COPY ask for a displacement after the Displacement keyword or
Enter at the base point prompt.

After the insertion point, the command-line INSERT now asks "Enter X
scale factor, specify opposite corner, or [Corner] <1>", then "Enter Y
scale factor <use X scale factor>", then the rotation, so scripts like
`-INSERT B1 20,20 1 1 0` place the block as written instead of rotating
it by the Y scale and running the rotation as a command. A point (or
Corner) at the X scale prompt gives both factors from the opposite
corner.
The Basepoint, Scale and Rotate options at the insertion point prompt
now work: Scale and Rotate preset the value and skip that prompt later,
Basepoint picks a new base point on the block at its definition
position.
The JSON form takes `scale: [x, y]` and `basePoint` too.

Typed RENAME / -RENAME (and REN) asks for the object type
[Block/Dimstyle/LAyer/LType/Material/multileadeRstyle/Plotstyle/
textStyle/Tablestyle/Ucs/VIew/VPort], the old name and the new name,
then runs the rename command body, so the checks and the single undo
step match the JSON form. An unknown old name or a refused new name
re-prompts. Material, Plotstyle and VPort read both names and report
"not available yet".
The JSON form now renames blocks, as its params doc promised. Every
INSERT follows the new name, in model space, layouts and nested block
definitions, including inserts that carry attributes. INSNAME and
dimension-style arrowheads follow too. Duplicate names (any case),
invalid names and anonymous blocks are refused. Multileader styles,
table styles, named views and UCSs can be renamed as well. A layer
rename no longer records two undo steps.

Running snaps only saw a block reference's insertion point. Now the objects
inside it snap where they are drawn: nested references and MINSERT arrays are
expanded, placed exactly by the reference's transform (non-uniform scale
turns circles and arcs into ellipses), and hidden objects or objects on layers
that are off are left out. Insertion also snaps to visible attributes.

Linetype text elements (FENCELINE1, GAS-style linetypes from DXF files)
were drawn as part of the gap. Each text is now placed where the element
that carries it ends, at every repeat of the pattern: in its text style's
font, at the element's scale times the style's fixed height and the
linetype scale, shifted by its X/Y offsets along and across the line, and
rotated relative to the line direction or absolutely. Runs drawn
continuous (pattern smaller than a pixel) draw no text, and coarse
previews without text skip it. Shape elements need SHX shape files,
which CADCraft doesn't read, so they still draw nothing.
FENCELINE1 carries its circle on the first gap, centred between the two
gaps, so it no longer sits on the start of the long dash.

Save As suggested `.dxf` for every untitled drawing, so saving new work as
DWG meant typing the extension each time. AutoCAD keeps this choice in
Options > Open and Save > "Save as".
- File > Default Save Format > DXF / DWG sets the format Save As suggests
for drawings that have no file yet. Drawings opened from a file keep that
file's format, as before. DXF stays the default.
- The choice is saved across restarts with the other preferences
(`saveFormat`), survives Reset Palettes, and is scriptable as
`ui.saveformat {format}` or the `saveFormat` UiState field.
- Ukrainian labels for the new menu entries.
On macOS the suggested `.dwg` name needs DWG in the Save As filter list
(#198) to survive the dialog.

* Extents: ignore rays and references to missing or empty blocks, as ZOOM Extents does
Opening real drawings in CADCraft often showed a tiny plan in a huge empty
canvas, because the extents included things that draw nothing:
- the base point of a RAY (Autodesk's own reference says infinite
construction lines and rays do not affect ZOOM Extents; an office plan in
our corpus carries two rays 1.98 million units from the building);
- the insertion point of an INSERT whose block is missing (a purged
definition, a bound xref that never came along) or empty (an unloaded
xref): a floor plan had such references 125 000 and 3.4 million units away.
XLINEs were already ignored; rays now are too, and an insert contributes only
what its block draws (attributes still count). Two regression tests use the
measured coordinates.

* Extents: skip invisible block entities, attdefs and blank texts
- Entities in a block definition count for an insert's (and a dimension
block's) extents only if they are not AttDefs, have common.visible set,
and sit on layer "0" or on a layer that is on and thawed. Dynamic blocks
keep hidden constraint geometry far from the visible part.
- Text/MText that is empty, whitespace-only or only "\~" has empty bounds.
- Tests cover each rule separately.

A wipeout was drawn only as its outline, so objects behind it stayed
visible on the canvas and in PNG, SVG and PDF output. The display list
gets a new primitive kind, Kind::Mask: the wipeout polygon as triangles
that every backend fills with its background colour (paper white for
SVG/PDF and plots, the raster background for PNG, the canvas colour or
the white sheet on screen), in draw order, so it hides what came before
it (DRAWORDER decides). The frame follows WIPEOUTFRAME: 0 none, 1 shown
and plotted (default), 2 shown but not plotted.
The GPU canvas drew all fills before all lines; it now splits the mesh
into draw-order groups at each mask (MeshData::breaks) and draws each
group's fills, lines and quads in turn. Infinite lines stay on top as
before.

A polyline with width was always filled as one continuous band. Now,
with a linetype, each dash is a filled piece of the band (tapers and arc
segments included) and the gaps stay empty; dots are drawn as a line
across the band. As for thin polylines, PLINEGEN runs the pattern along
the whole polyline, otherwise it restarts at every vertex, and a pattern
too small to see (min_dash) fills the whole band.
linetype::ranges lays the pattern out along a length; wide::dashed cuts
the band at those distances.

display_rgb flipped every near-white colour to black on paper and every
near-black colour to white on the dark canvas, so ACI 51/255 and
true-colour white printed black and dark index colours showed white.
Display-list primitives now carry an aci7 flag set when the colour
resolves to 7 (directly, by layer or by block); only those flip.

-BLOCK was an alias of BLOCK, so the selected objects were always
converted to a block reference; a script doing -BLOCK then INSERT ended
up with an extra reference. -BLOCK is now its own command: the command
line erases the selection, and its JSON form defaults to keep "delete".
BLOCK (menu Make..., typed BLOCK) and the "block" JSON form still
convert by default.
Both forms ask 'Block "<name>" already exists. Redefine it? [Yes/No]
<N>:' when the name is in use; No asks for the name again.
Session::start resolves a dashed name to a command with that id (the
same change as #280's -ATTEDIT).

The offset copy of a spline was always rebuilt with the open fit-point
interpolation, so a closed spline came out open with a corner at its start
point. Use Spline::from_fit with the source's closed flag, which gives a
periodic spline for closed input.

wblock {name, base} ignored base and always measured from the block's
own base point. base (in block coordinates) now overrides it, the way
it already worked for selected objects. In both modes the base point
becomes the written drawing's origin, and $INSBASE is 0,0,0.

The linetype library is defined in inches, and LINETYPE loaded it
unchanged into metric drawings: DASHED was 0.5 mm on, 0.25 mm off at
LTSCALE 1, so dashed lines looked solid. CAD programs load ISO-scaled
definitions when MEASUREMENT is 1 (the same patterns with lengths times
25.4). library::standard_linetypes_for(d) does the equivalent with our
own definitions: in a metric drawing every length (dashes, gaps, text and
shape size, offsets) is scaled by 25.4 as it is loaded. LINETYPE and the
CENTER linetype that CENTERMARK/CENTERLINE load use it. Definitions
already in a drawing are not changed.

Objects whose lineweight resolves to Default were always drawn and
plotted at 0.25 mm. They now use LWDEFAULT (hundredths of a mm, 0..211),
falling back to 0.25 mm when it is unset or out of range. All backends
(canvas, PNG, SVG, PDF) read the width from the display list.

Session::execute and interactive input already ran under catch_unwind;
the machine factory, begin (the first step of Session::start), prompt and
preview (called by the UI every frame) did not, so a panic there took
down the app. Session::start now wraps each machine in guard::Guarded,
which runs all of its steps under catch_unwind. A panic in the factory,
begin or input ends the command with an internal error and the session
restores the drawing, as for input. prompt and preview can't end the
command, so they fall back to an "Internal error" prompt and no preview,
and the next input ends the command the same way. AGENTS.md/CLAUDE.md
name the wider guard.

* Array commands: ARRAY, and the edit-array option loops for ARRAYRECT/ARRAYPOLAR (#230)
ARRAY (alias AR) selects objects, asks for the array type and continues as
ARRAYRECT, ARRAYPATH or ARRAYPOLAR. ARRAYRECT no longer creates a fixed 4x3
grid right after selection: it previews the array and loops on
ASsociative/Base point/COUnt/Spacing/COLumns/Rows/Levels/eXit. ARRAYPOLAR
asks for the center (or Base point), then loops on Items/Angle between/
Fill angle/ROTate items/eXit. The copies are created on eXit or Enter.
Associative arrays, levels and polar rows report "not available yet" and
return to the loop without consuming the next input.
The array commands move to cmd/array.rs. Arrays stay non-associative
copies, and the JSON forms are unchanged. A full clockwise polar fill
(-360) no longer puts the last item on top of the source.

* Arrays: refuse arrays over MAXARRAY instead of hanging or shrinking them (#230)
`arrayrect {"rows":1000000,"cols":1000000}` was clamped to 1000x1000 and
then created a million copies of every selected object, which hangs the
app. ARRAYRECT, ARRAYPOLAR and ARRAYPATH (JSON and interactive, also via
ARRAY) now count items x selected objects and refuse an array over the
new MAXARRAY session variable (default 100000, settable 100..10000000)
with a message naming the limit, instead of clamping the counts and
silently creating fewer copies. The interactive count prompts accept at
most what still fits under MAXARRAY.

SPLINE Close now builds a smooth closed (periodic) curve through the fit points
instead of repeating the first point. The geometry gets Spline::from_fit_points_closed:
chord-length parameters including the closing chord, a periodic knot vector, and the
first three control points repeated at the end. The fit data no longer duplicates the
first point. DXF writes group 70 bit 2 (periodic) for it, and a file whose closed spline
needs refitting is refitted closed. SPLINEDIT Close/refit/move and fit-point grips keep
a closed spline periodic.
SPLINE Method asks Fit/CV, and CV continues as SPLINE by control vertices. Knots, Object,
start/end Tangency and toLerance report "not available yet" and stay at the prompt.
Garbage text reports "Point or option keyword required.".
POLYGON with a typed radius puts the bottom edge horizontal for Inscribed and for
Circumscribed. The JSON form uses the same orientation when no angle is given.
CIRCLE reports "Point or option keyword required." for an invalid token at the centre
prompt, and "Invalid point." at the 3P/2P point prompts, then asks again.

The Save As dialog listed DXF, SVG, PNG and PDF, though CADCraft writes
DWG. On macOS the dialog accepts only listed extensions, so a name typed as
`part.dwg` was changed to .dxf and the drawing was saved as DXF.
Save As now lists "Drawing (DWG)" too. The existing suggested-type-first
ordering does the rest: a drawing opened from DWG defaults to DWG, while new
drawings and DXF files keep DXF first. The list moves into
`filters_for_save` with a unit test, and the label gets its Ukrainian
translation following "Drawing (DXF)".
Related to #14 (the Open half was fixed in #21).

AutoCAD and BricsCAD store a mirrored block reference, and many 2D
entities drawn in a mirrored UCS, with extrusion (0,0,-1). Their points
and angles are then in an OCS whose x axis runs the other way. The reader
only honoured that for CIRCLE, ARC, LWPOLYLINE and SOLID/TRACE, so
mirrored blocks, hatches and texts landed on the wrong side of the
y axis (e.g. profile blocks at x -57618 instead of +57618).
- INSERT: insertion point through the OCS, negative x scale, opposite
rotation and negative column spacing. Only for extrusions parallel to
-Z (x/y noise up to 1e-3); a tilted block plane needs a 3D transform
that Insert cannot hold and is left as read.
- HATCH and R12 2D POLYLINE: boundary x and bulges mirrored like
LWPOLYLINE; the hatch pattern angle mirrors too.
- TEXT/ATTDEF/ATTRIB and MTEXT: points through the OCS; drawn readable
(MIRRTEXT = 0) with the mirrored footprint, so the direction turns and
left/right justification or attachment swap.
- ELLIPSE: centre and major axis are WCS, but the minor axis is
extrusion x major, so the parameter range is negated.
- DIMENSION: the text midpoint (11) is the one OCS point.
Checked against an independent DXF library on private drawings: every
INSERT transform (plain, mirrored, tilted) matches, as do the mirrored
arcs, ellipses, polylines and hatches. The remaining extents outliers in
those drawings come from references to empty blocks, which still add
their insertion point to the extents.

With DIMASSOC on, every chained dimension looked up the objects under
its definition points by scanning the whole space, and each point adds
an entity, so a long `points` list took quadratic time (16,000 points:
2.7 s continue, 10 s baseline). The chain now builds one x-sorted
SnapIndex up front. Dimensions are no snap targets, so the index stays
valid while the chain adds them, and each lookup is a binary search. The
index picks the same snap as find_snap: lowest rank first, then the first
object in space order. A call with more than 100,000 points is refused.

Redefining a block with a selection that holds a reference to that block,
directly or through nested blocks, is now refused with "Block "B"
references itself." and changes nothing. Before, the block ended up
containing itself and lost its original geometry. At the command line
the message ends -BLOCK, as for any definition that can't be made.
Redefining with a name that differs only in case (Door, then DOOR)
replaces the existing block instead of adding a second one.

dxf_ext::is_paper_view (#225) matched any 1000 string in the CADCraft xdata, but later strings
are layer names (VPFROZEN, VPCOLORS). A real viewport with a frozen or recoloured layer named
PAPERVIEW was therefore dropped on read. Only the first string, where the writer puts the
marker, counts now. Regression test in tests/paperview_marker.rs.

With PSLTSCALE on (the default), dashes of model-space objects seen through a
viewport keep their paper-space length whatever the viewport scale; before,
a 1:100 viewport drew them 100 times too short, so dashed lines looked solid
in layouts and PDF plots. PSLTSCALE 0 keeps the old behaviour.

POINT objects were always a one-pixel dot. They now draw the figure PDMODE
picks (nothing, plus, cross, tick, with an optional circle and/or square)
at the size PDSIZE gives: drawing units when positive, a percentage of the
view height when negative, 5 % when 0. The canvas passes its view height;
exports and plots use the plotted window or the extents.

* Bound block expansion in drawing and extents (fixes#255)
MAX_BLOCK_DEPTH bounds only the depth of nested block references, so a
small DXF with a self-referencing block, blocks that each insert the next
several times, or one large MINSERT expanded to billions of copies and
hung the app (drawing, PNG/SVG/PDF export, extents, saving).
- render: a per-display-list budget (MAX_BLOCK_EXPANSION, 2 million
block copies and entities drawn inside blocks); past it the remaining
block contents are not drawn.
- doc: entity_bounds computes each block's content bounds once per call
and reuses them for every further reference.

DWG saves convert our R2000 DXF with acadrust, which wrote an R2000 DWG:
no true colours, no entity transparency, no table styles, and its R2000
reader puts every layout's paper-space entities into the first layout.
The bridge now writes at least AutoCAD 2004 (AC1018) DWG; the DXF itself
stays R2000. acadrust goes to 0.6.3 (explicit transparency encoding).
DWG doesn't store viewport ids: readers number a layout's viewports in
order, and id 1 is the paper-space viewport (the sheet). CADCraft keeps
that one implicit, so its first viewport came back as id 1 and wasn't
drawn. The DXF writer now puts a paper-space viewport (id 1, marked with
CADCraft xdata) ahead of a layout's viewports when it has none, and the
reader drops it again. Viewports also get status 68 and the always-set
bit 32768 in group 90, so other readers don't take them as "off".

On wasm, saving skipped the file write but still marked the drawing saved,
renamed its tab and reported success, so nothing reached the user. Saving
now hands the bytes to a host delivery hook (`file::set_deliver`); the web
app installs a small web-sys download helper (Blob + object URL + temporary
<a download>), reusable for other files such as plots. Without the hook, or
when the download can't be started, save errors and the drawing stays dirty.
A started download counts as saved and keeps the name for later QSAVEs.
The web app's Save/Save As (menu, close prompt) download under the drawing's
name, as there is no file picker in the browser.

The web app ran CadApp with Services::default(), so OPEN found no file
picker and returned without doing anything: no picker, no message.
The web app now installs an open picker (apps/cadcraft-web/src/upload.rs,
web-sys only): a hidden <input type="file" accept=".dxf,.dwg"> is
clicked, the chosen file is read in the background (Blob.arrayBuffer)
and handed to the app on its next frame, which runs OPEN with
{data, name} through the new CadApp::open_bytes. Cancelling the picker
does nothing. Files dropped on the page, which eframe hands over unread
on the web and the UI ignored there, take the same route.
Files over 256 MB (CadApp::MAX_OPEN_BYTES; the browser holds the drawing
several times while decoding it) are refused before they are read.
Unreadable or rejected files report on the command line and in the
status bar; nothing panics.

The canvas hides the OS cursor (CursorIcon::None, which winit turns into
ShowCursor(FALSE) on Windows) and draws its own crosshair, so Windows
Magnifier's "follow the mouse pointer", screen readers, recorders and

Cursor (ui.toggle.systemcursor, ui.set {"systemCursor": true}, or
CADCRAFT_SYSTEM_CURSOR=1 at startup) keeps a system crosshair visible at
the centre of the drawn one.

AppKit draws the traffic lights centred in its standard 28 pt title-bar
band, and the integrated title row is that band, but the title text sat
1 pt below the centre line. It is now centred on the lights. Neither
winit nor eframe can move the lights without AppKit calls (unsafe), so
the row fits them instead, as in WordCraft (storytold/wordcraft#255).
The geometry lives in chrome.rs. A long drawing name in a narrow window
no longer slides under the lights: the title starts after them, with the
same gap the lights keep from the top of the window.

UNDO now prompts "Enter the number of operations to undo or
[Auto/Control/BEgin/End/Mark/Back] <1>" and undoes that many; Enter undoes
one. Its other options say they are not available yet (Auto and Control
still take their value), so nothing that follows is run as a command.
The JSON form (`undo {count?}`) is unchanged.
U is its own command, as in AutoCAD: it undoes one operation without
asking and is what Edit > Undo, Cmd+Z and the toolbar button run.
An interactive command outside undo that changed the drawing (UNDO)
records no undo step when it finishes, matching `execute`.

TEXTEDIT's prompt no longer reads "or or". Undo reverts the last edit made

after the first line and running the next one as a command. The Text

Multiple points measures a path and reports the running and total
distance. Arc now says it is not available yet instead of being ignored
(or ending AREA as Total).

"Specify the reference angle <0>" takes a typed angle or two points;
"Specify the new angle or [Points] <0>" takes a typed angle, a point

"not available yet" and the values that followed were misread or run as

ELLIPSE: after Rotation the next value is the rotation around the major

ellipse parameters and Angle switches back to true angles.

Raster images: the reader now follows an IMAGE's group 340 to its IMAGEDEF
and keeps the file path and the definition's name (its ACAD_IMAGE_DICT
key), pixel size and resolution unit. It also keeps the clip boundary (in
pixel coordinates), the clipping state, the display flags and
brightness/contrast/fade. The writer emits the IMAGE entity, plus one
IMAGEDEF per path and name, an IMAGEDEF_REACTOR per image,
RASTERVARIABLES, the ACAD_IMAGE_DICT and ACAD_IMAGE_VARS entries in the
named object dictionary, and the four CLASS records, as the DXF Reference
describes. An image without a clip boundary gets the full-image rectangle.
DWG save keeps the same data, except the resolution unit, which the DWG
bridge drops. The pixels are still not loaded.
Entity types CADCraft doesn't model (MLINE, MULTILEADER, 3DSOLID, REGION,
MESH, ...) are still not written. Writing their raw groups back into the
R2000 file would leave references to objects that aren't kept
(MLINESTYLE, MLEADERSTYLE, ACIS data in later versions), and some of the
types don't exist in R2000 at all. Another CAD program could then reject
the whole file. Instead, qsave, saveas and document.bytes now say on the
command line which ones weren't saved ("Not saved (CADCraft can't write
these object types yet): 1 3DSOLID, 2 MLINE") and list them by type in the
result's `notSaved`. `cadcraft-cli run --save` and `convert` print the
same line.

Saving to DXF and reopening lost several table and object-section items.
They are now written and read as the DXF Reference describes:
- LTYPE: embedded text and shape elements (74 type flags, 75 shape number,
340 STYLE, 46 scale, 50 rotation, 44/45 offset, 9 text). Shapes from a
shape file get an unnamed shape STYLE record (70 bit 1). DashElement
gains an `absolute` flag for absolute rotations (74 bit 1). The built-in
FENCELINE1 names its text style (Standard).
- MLEADERSTYLE objects in ACAD_MLEADERSTYLE with arrow size, text height,
landing gap, dogleg length and text style, plus $CMLEADERSTYLE, so the
current multileader style survives reopening.
- LAYOUT plot settings: device (2), plot style table (7), plot area (74),
custom scale (142/143, 147), scale to fit (70 bit 16 with 75 = 0),
centred plot and lineweights (70 bits 4 and 128). The layout's saved
paper-space view goes in CADCraft xdata on the LAYOUT object.
- VIEW and UCS table records, and GROUP objects in ACAD_GROUP (members
that were written to the file). A named view's layer state is CADCraft
xdata on the VIEW record.

properties:
- Thickness (group 39) is written for LINE, POINT, CIRCLE, ARC, TEXT,
SOLID, TRACE, LWPOLYLINE and POLYLINE when non-zero.
- POINT writes its X-axis angle (group 50).
- HATCH: the origin goes into the pattern lines' base points (43/44), so
other programs see the shift, and travels with the background colour as
CADCRAFT xdata (1000 HATCH, 1011 origin, 1000 colour name); the DXF
Reference has no groups for either. It is appended to the gradient
xdata when there is one. The reader takes the elevation from the z of
the first group 10.
- Xref blocks get BLOCK 70 bit 4 and their path in group 1, and the
reader reads the path.
- The built-in "CADCraft Stroke" font is still written as "txt" for other
readers; its name travels as CADCRAFT xdata (1000 FONT) and is used
while group 3 is still "txt".
- Polyface (70 bit 64) and polygon mesh (bit 16) POLYLINEs from other
programs are read as 3D faces instead of a 3D polyline through their
vertices; face records no longer become vertices at the origin. Bad
indices and counts are skipped.

The ATTDEF writer put only the invisible bit into group 70, so constant
attribute definitions came back as variable ones: INSERT then created an
attribute for them, and other programs stopped drawing their text. The
constant bit (2) is now written too.
BLOCK's description was never written (BLOCK group 4) nor read, and the
insertion units (BLOCK_RECORD 70) and explodability (280) of blocks were
neither read nor written. All three now round-trip.
