A layout opened for the first time - one whose sheet viewport had to be
made, or one created in this session - gets a viewport centred on the
printable area, 0.8 of its width and height, zoomed to the model's
extents, while LAYOUTCREATEVIEWPORT is on. The profile variable takes
ON/OFF or 1/0 and is kept with the settings.

- The Image tab gains an Adjust card: X/Y offset in pixels (-2000..2000)
and X/Y scale (-10..10, tenth steps, a negative scale mirrors, zero keeps
the image's scale) with spinners and Reset, inactive while the image is
stretched; Keep aspect ratio is a switch and makes both scales follow.
- The preview shows the image at its offset and scale, tiled when tiled,
and a stretched image kept to its aspect ratio covers the view.
- Automation: step=<field>,+1|-1 and reset; offset/scale take any numbers.
- Shaded with edges, Shades of Gray and Sketchy have catalog entries in
every language.

- The background image texture is not an sRGB view: the image is drawn with
its own colours, as the solid and gradient colours are.
- An entered paper-space viewport shows its named visual style (Realistic,
...) in the render-mode picker, and a mode picked there is recorded as the
viewport's visual style.
- The view_background automation action takes offset=x,y and scale=x,y.

- Gradients: the middle colour sits (horizon - 0.5) viewport widths from the
centre and blends over height viewport heights each side; two colours
blend over a viewport height each side.
- Image backgrounds: offset in device pixels (right, down), negative scale
mirrors, fitted with aspect ratio covers the viewport; the dialog keeps an
image's offset and scale.
- Layouts: a model-space view restored on a sheet asks for the viewport,
enters it and gives it the view's camera, background and visual style;
inside a viewport the view goes there; a paper-space view's background is
kept on the sheet viewport but not drawn; floating viewports draw their
background.
- Background objects no view or viewport uses any more are erased; a view
without a background restored where the viewport already is leaves the
viewport's background.
- The viewport's named visual style (Realistic, ...) shows by name and the
render-mode picker records its style on the viewport record.

An image background not fitted to the screen keeps its own pixel size
(times its scale), centred on the viewport and moved by its offset, as
the reference draws it; tiling repeats it from there.

Measured against the reference: a two-colour gradient reaches its end
colours a viewport beyond the edges, and the bands blend linearly.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The rotation is stored in degrees and turns the bottom-to-top direction
counter-clockwise, measured in pixels; a two-colour gradient blends from
the bottom colour to the top one across the whole viewport.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Restoring a named view gives the model viewport the view's visual style
(the closest render mode), and a 2D wireframe viewport shows no
background, as in the reference.

Color, Gradient and Image at the background prompt open a Background
dialog (None / Solid / Gradient / Image, preview, solid colour, two- or
three-colour gradient with rotation, image file with position and
scale). Apply links the view to a new background object in
ACAD_BACKGROUND; restoring a view gives the model viewport a copy of
it (or none), and saving a view copies the viewport's background.

A taper angle given in one EXTRUDE was applied to every later
extrusion. As in the reference, a new extrusion has no taper; the last
angle stays the Taper angle prompt's default.

The command left its sources selected when DELOBJ keeps them, so the
next command took them as its preselection; the reference clears the
selection after REGION.

A lofted surface's region cross sections are recorded as the curve round
each region, as the reference records them; a region recorded as a
region made the reference refuse to open the drawing.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The reference writes none; a draft distance on an extruded surface made
it re-extrude the surface with a taper when the profile changed.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The polyline round a region is written about the region's normal in its
object coordinates with an identity transform, as the reference writes
it; a rebuild from the history placed a polyline given in plane
coordinates with a frame at the wrong place once the region moved. Arcs
of one circle making a whole turn are recorded as that circle.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A swept, extruded or revolved surface made from a region records the
region as the curve round it, as the reference does: a lone circle or
whole ellipse as itself, a loop of lines and arcs as a closed polyline in
the region's plane. A region recorded as a region made the reference
refuse to open the drawing (modeling error 58000).
A region read by an associative action carries the step its edge names
belong to (ACAD_STEPID), so the reference finds the edges again and the
surface follows the region.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The surface extrusion, the extrusion along a path, revolve history and
embedded profiles refused a region whenever it had more than one display
wire, which a region of several edges always has. They now refuse only a
region with holes, and a region's loops for a solid extrusion come from
its modeler edges.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A region keeps one display wire per edge, so a region of several edges
gave no polygon and could not be extruded (solid or surface), and a
circle region was extruded from its display polygon. Profiles of a region
with one boundary loop now come from the region's modeler edges.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A region of several edges kept its display wires one per edge, so the
surface extrusion found no polygon and refused it.

A new drawing carries the visual styles the reference's new drawing has
in its visual style dictionary. -VIEW sEttings Visual style offers them
(2dWireframe as "2D Wireframe") and a saved view starts with the 2D
Wireframe style.

A swept, extruded, revolved or lofted surface made from a region now
reads the region through one geometry dependency per edge, each naming
its edge by a persistent subentity id recorded in the drawing's
subentity manager, so the surface follows the region. A lofted surface
keeps one continuity and bulge value per cross section.

A dimension carries its graphics in a block of its own, drawn in that
block's frame, and the entity records where the frame sits. The renderer
inserted it at the origin instead, so every dimension whose file carries a
non-zero insertion point drew far from the geometry it measures — the whole
picture offset by that point. Dimensions inside block definitions are where
this shows: a drawing of plan blocks scattered their dimension graphics
thousands of units away, over empty sheet.
The picture now follows the dimension's insertion point, rotation, scale and
extrusion, the way any block reference is placed.

A drawing whose plan content is built from blocks reaches thousands of
definitions, and each one took a buffer of its own for its segments and
another for its constants, plus one per placement run. The payloads are a
few hundred bytes, but every allocation costs a page: 14k definitions ask a
device for 1.8 GB to hold 12 MB of geometry. D3D12 runs out, the failed
allocations stay invalid, every later frame writes to them, and the session
dies in the staging belt.
The definitions of a build now share one arena: constants in a single
uniform buffer addressed by dynamic offset, segments in a single geometry
buffer addressed by first_vertex, placements in a single instance buffer
addressed by first_instance, with another arena started whenever one of the
three would outgrow the per-buffer budget. The cache holds the records
rather than the buffers, so a build the device rejected poisons nothing.

SURFACEASSOCIATIVITY now keeps EXTRUDE, REVOLVE and LOFT surfaces linked to
their sources: the profile (and axis object) or cross sections are kept, the
surface is made again when they change, and the drawing's associative
network carries an action with the extruded, revolved or lofted surface
action body, its path parameters and value parameters as the reference
writes them. Swept, extruded, revolved and lofted surfaces can read
splines (NURBS edge curve, fit-point splines through their fit points)
and ellipses (elliptical edge curve). Associative surfaces of a file
opened here follow their sources too.

An orthographic preset sets its orthographic UCS while UCSORTHO is on
(*FRONT*, *RIGHT*, …; TOP returns to the world UCS); presets no longer
flip to the opposite view when repeated. -VIEW runs as its own command:
Window asks for the name and corners, sEttings loops over Background,
Categorize, Layer snapshot, live Section, Ucs and Visual style with the
reference prompts and messages, Save keeps the UCS with the view while
UCSVIEW is on and Restore brings it back. UCSORTHO and UCSVIEW are
profile variables.

-VIEW asks "Enter an option [?/Delete/Orthographic/Restore/Save/sEttings/
Window]:" and takes the orthographic and isometric presets (TOP, BOTTOM,
FRONT, BACK, LEFT, RIGHT, SWISO, SEISO, NEISO, NWISO, also with a leading
underscore) directly, Orthographic asking for the face with <Top> as the
default. Keyword prompts accept a leading underscore on their keywords.

The reference cannot open a drawing whose extrusion history has a taper
and leaves the profile frame to be computed (ErrorStatus 53). Extrusion

Swept surfaces made with SURFACEASSOCIATIVITY on keep their profile and
path and are written as a swept-surface action of the drawing's
associative network, reading the profile and path and their scale and
twist expressions. They follow edits of their sources.

A single profile's base point comes from the path it is swept along: a
path leaving the profile's plane from inside the profile sweeps it where
it stands. Kernel 30b3810: pcurves in the edge's parameterisation (valid
spline-faced sweeps), corner crossings fitted to the modeller's
resolution, run faces through stations evenly spaced along the run.

A closed 3D polyline profile that does not lie in one plane sweeps a
surface with the reference's refusals. Swept surfaces made with an
Expression scale or twist follow the named parameters, and reference
surfaces linked through their associative action are picked up on open.
Saving keeps the associative actions the constraint graph does not
rebuild and stores each scope network through its own dictionary.
Kernel 23138fc, codec 64fe2a6.

- An open path is swept from its end nearest the pick point (in plan), as
the reference does; the record keeps the original path and the placed
frame marks the start.
- Kernel from ramox81/cadkernel 1df75f5: one face per path run for
twisted, scaled and spline sweeps, placed records swept from the placed
end, end caps without pcurves.

- Scale and Twist take an Expression evaluated with the drawing's
parameters; invalid input prints the reference message and asks again.
- The scale and twist prompts use the reference wording and defaults.
- The SWEEP prompts and refusal messages are in the locale catalog with
translations in every locale.

- 3D polyline profiles are recorded as wire bodies, like 3D polyline paths.
- Refused sweeps print the modeling error code and "Unable to sweep N
selected objects."; a scaled sweep rejects closed and cornered spatial
paths with the reference messages and asks for the path again.
- Scale > Reference asks for start and end reference lengths (start / end).
- Bank stays on for later sweeps until a twist angle is entered.
- Refused twist/scale edits in Properties print the modeling error code.

New sweep records store the source and placed profile frames, the
default mitred joint, groups 292-294 and a 3D polyline path as a wire

txt, simplex and romans keep the reference fonts' printable ASCII pen

The letter spacing after a line's last stroke-font glyph is left out of
the width used for centring and right alignment, so a right-aligned

MTEXT paragraphs keep left-to-right order and their attachment's
alignment even when they start with Hebrew or Arabic: a run of
right-to-left words (with the spaces between and after them) reads
backwards in place, and inside a word each right-to-left letter run is
reversed on its own while digits, punctuation and Latin keep their
order. Shaped text gets a left-to-right paragraph direction, so TEXT
follows the bidirectional rules with a left-to-right base, and a TEXT
line that starts with Hebrew or Arabic is no longer right-aligned. A
paragraph's leading spaces keep their width and trailing spaces are left
out of the width used for centring and right alignment.

Layout glyph cells carry their unrotated cell, so a field box in rotated
MTEXT is placed exactly; multi-line attributes box each line of a field
from their own layout cells and single-line attributes split on \P per
line; shaped words (TrueType fonts, right-to-left and complex scripts)
take the shaper's glyph cells for their characters instead of evenly
divided slots. The field background is also drawn for text rendered as
shaped strokes.

Table cell fields show their stored value; only formula cells evaluate
live. UPDATEFIELD on a block reference also updates the fields of its
block definition, and on a table the fields of its cells; a changed
table cell text redraws the table. The FIELDDISPLAY box is placed from
the text layout (MTEXT layout cells, TEXT / attribute pen advances) and
spans 0.345 text heights below the baseline to 1.19 above it.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
MTEXT draws its stored text instead of re-evaluating fields on every
redraw. Fields update on their evaluation events as the reference does:
open (1), save (2, not autosave), plot (4) and REGEN/REGENALL (16), each
masked with the drawing's FIELDEVAL (variable dictionary, 0-31, with the
reference's prompt and message), and the new UPDATEFIELD command
(selection, attributes of selected block references, "N field(s)
found." / "N field(s) updated."). A Date field (on demand only) keeps
its value until UPDATEFIELD. The FIELDDISPLAY gray box now covers each
field's own glyphs, one box per line it spans, instead of the whole
text. Codec moved to the update_fields / field_spans revision.

A plot stamps PlotDate fields, but the redraw only dropped the host's
own tessellation: an attribute is drawn by its INSERT and a host inside
a block definition by every reference to the block, so both still
showed the old value on screen and in the plotted output. The changed
hosts now redraw through their INSERT / the block's references (block
cache refreshed), without re-tessellating anything else. The codec is
patched to the field format code fixes.

The codec now reads AcDbCenterMarkActionBody and AcDbCenterLineActionBody

The row menu is a small overlay widget: a click on a submenu entry opens

Model Views lists named model views and places them on the current sheet

their values when a set changes; named views keep their centre relative to
the target. Codec pin moves to the revision with these field helpers.

Saving filled every 3D solid without stored wires with tessellated display
