(Réseau rectangulaire / polaire / trajectoire) and Lissage for loft.

add_layout took the sheet viewport out, so the first viewport added to
the layout afterwards (by automation, or a plugin) was read as the sheet
and the scale pill and paper camera followed it. The sheet now stays and
is fitted to the page when the layout first opens; a layout saved before
that is still written without viewports.

Opening a layout whose page setup was never filled in took every viewport
out of it, including viewports onto the model a file carries (plenty of
DXF writers leave the paper fields empty). With only the sheet taken out
instead, the next viewport would have been read as the sheet. The sheet
is now fitted to the new page and every other viewport stays.
A layout saved as never opened keeps its state when it already holds a
viewport onto the model (one added by automation), and only its sheet is
taken out otherwise.

REFCLOSE Save on an xref replaced the referenced file's model space with
the working set alone. With the Nested selection method the objects that
were not checked out stay in the definition, but they were deleted from
the file on disk. Write back every object of the saved definition, and
copy the file to .bak first when ISAVEBAK is on, as a drawing save does.
Also translate the new REFEDIT prompts into the other 20 locales; the
catalog test requires every locale.

The brightness/contrast cache keyed entries by the source buffer's
address without holding it, so a reloaded image whose new buffer landed
at the freed address could be shown with the old file's pixels. Each
entry now holds its source. The new functions had also been inserted
between resolve_image's doc comment and the function, merging that text
into the lookup table's documentation; it is back where it belongs.

Brings in the merged codec PRs (XCLIP transforms in the reference order,
table entries added after load get handles in DXF, default APPID handle
collision, viewport ShadePlot and grid flags) and the kernel's sweep and
off-plane revolve work.

MATCHPROP transfers properties from a source object onto others, so the CAD
crosshair gives way to a monochrome paintbrush whose tip sits on the pick
point - the AutoCAD feel for the same command.
The glyph borrows the crosshair's own colour (including a user-customised
one) and uses a single stroke weight plus one filled wedge, so it reads as
part of the CAD cursor family rather than clip-art. It is drawn instead of
the crosshair, never on top of it, and only while the command is armed.
The web build has no font folder, so a text style whose TrueType file is
not a bundled Noto subset falls back to it. font_register takes the file
from the host page:
{"op":"font_register","file_name":"Brand-Regular.ttf","data_base64":"…"}
The faces join the font database, file_name resolves to the family of
the first face (case-insensitive, without directory, like installed
fonts), and open drawings lay their text out again (fallback glyph
cache cleared, text geometry invalidated per tab). The reply names the
family and the number of faces. Bytes without a face fail with
font_invalid. SysFonts::by_file becomes updatable for this.
Proposed in #1771.

A copied entity used to keep its source's extension-dictionary
handle, so the copy and source shared one tree and edits crossed
between them. In-drawing copy now clones the whole tree onto fresh
handles: dictionary entries, owners, reactors, nested xdictionary
links, and XRecord handle references that land inside the tree are
remapped; references leaving it stay pointed at the originals. A
dangling or missing root leaves the copy without an extension
dictionary rather than sharing. Annotative context trees and the
paste/export clone path are unchanged. Undo stays on the full
snapshot path when a tree is cloned.
ARRAYEDIT picks an associative array (or takes the preselected one) and
its Source option opens the objects every item repeats in the Block
Editor; saving there updates all items at once. Counts and spacings stay
in Properties.

One finger already worked as the mouse. Two or more fingers now make a
gesture instead of fighting over the cursor: two drag to pan and pinch to
zoom about the fingers, three drag to orbit; a quick two-finger tap opens
the context menu, a three-finger tap zooms to the extents and a quick
three-finger swipe up shows the isometric view. While a gesture runs the
drawing area's own pointer handling keeps out, and the press the first
finger started is dropped.

Ctrl+click on a polyline selects the segment under the cursor (again to
drop it); several segments can be picked. Only the picked segments are
highlighted, and MOVE, ROTATE, SCALE and MIRROR then change just their
vertices, so the neighbouring segments stretch to follow. Any other
selected objects are transformed whole as before.

A paste that finds no text now reads an image off the system clipboard
on desktop as well as on the web. The pixels are written as a PNG beside
the drawing (or in the config folder for a drawing never saved) and
placed as a raster image at the cursor, the same way the web paste
attaches a screenshot. PASTESPEC falls back to the same image paste when
the clipboard holds neither objects nor text.

SECTIONCULL keeps only what the selected section object (or the live
section of the space) shows: solids, surfaces and closed meshes are cut
to it with the same planes the live section uses, open meshes are
clipped face by face, and every other object wholly outside it is
erased. Objects across the boundary that cannot be cut stay whole. One
undo step.
The section's bounding planes are gathered once (section_planes) and
shared by the live section and the cull.

COMPARE picks a drawing (or takes its path) and matches its objects with
this drawing's by what they draw: type, layer and tessellated geometry,
so an unchanged copy matches whatever its handle. Objects only here are
outlined in green, objects only in the other drawing in red, over the
current drawing, and Next / Previous zoom from one difference to the
next with a count in the prompt. A moved or edited object shows as one
of each. eXit (or Esc) clears the overlay.

With the new Associative option on (the default), ARRAYRECT and
ARRAYPOLAR build the array the way the drawing format stores one: the
selected objects move into an anonymous source block, an anonymous
array block holds one ByBlock reference to it per item, an INSERT of
the array block takes their place, and an AcDbAssocAction with an
AcDbAssocArrayActionBody, its three dependencies, the BaseNormal /
Origin / basePoint parameters and the value parameters tie them
together in the model-space network. The array is then edited from
Properties like an array read from a file.
The option flips with AS and is remembered for the session; on a
rotated working plane the commands keep making plain copies. Saving
drops the action of an array whose reference was erased or exploded.
Checked: created arrays reopen as associative with their parameters
and items, and the ODA converter reads the saved DWG without errors.

An associative array is an AcDbAssocAction with an
AcDbAssocArrayActionBody, dependencies on the array INSERT, the block
holding the item references and the block holding the source objects,
and value parameters (Items, ItemSpacing, Rows, …). Selecting the array
INSERT now shows its counts and spacings in Properties; changing one
places the items again and rewrites the item references, the body's
item records and the parameter values together, in one undo step, so
the drawing stays associative when saved.
Rectangular arrays follow their RowProfile axis, AxesAngle and base
normal; polar arrays turn about the centre recovered from their first
item, Radius and StartAngle. Both match the stored items of the
associative arrays in the sample drawings (122 of 123 rectangular, all
polar items of the polar samples). Path arrays are shown read-only.

FBXEXPORT (also EXPORTFBX) saves every 3D mesh of the drawing (solids,
surfaces and meshes, at full display resolution) as a binary FBX 7.4
file for visualisation tools: one model per object with its geometry,
face normals and a material in its display colour. Axes stay Z-up and
the unit scale follows the drawing's insertion units.

A section volume now shows grips on its top and bottom faces, so its
height is pushed and pulled in place like its sides, not only through
the Properties palette. Live sectioning also cuts MESH, polygon mesh and
polyface mesh objects that close a volume, drawing each as the capped
solid it bounds in every visual style.

SLICE now takes MESH, polygon mesh and polyface mesh objects. A mesh
that closes a volume is sliced as a solid, so each side is capped and
becomes a 3D solid. An open mesh, such as a pipe run imported without
end caps, is clipped face by face and each side stays a mesh, open
along the cut. Keeping one side or both works as for solids, in one
undo step.

MOVE, ROTATE, SCALE and MIRROR updated a MESH, polygon mesh or polyface
mesh but rebuilt the display only for solids, regions, bodies and
surfaces, so a transformed mesh kept being drawn where it was. Meshes
now go through the same display refresh.

Options > Display gains Window Elements with "Show the menu bar"
(MENUBAR) and "Show the ribbon" (RIBBON / RIBBONCLOSE); Options > User
Preferences gains a Hatch switch for HPASSOC. The command line now
starts at 80 % opacity so the drawing shows through it.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
MENUBAR 1 shows File, Edit, View, Insert, Format, Tools, Draw,
Dimension, Modify, Parametric and Help menus above the ribbon; every
entry runs an existing command, and a test keeps each entry pointing at
a registered command. RIBBONCLOSE hides the ribbon and RIBBON brings it
back, so the menus can replace it. Both choices persist.
Also translates the "File" label, which every locale had left in
English.

Opening the block editor brings up a Block Editor ribbon tab with
Edit / Save / Discard, Attribute Definition, and the geometric,
dimensional and parameter tools that drive parametric blocks. The tab
is only listed while a block editor session is open, and leaving the

ADJUST gathers raster images or PDF/DWF/DGN underlays (other objects are
dropped silently, pickfirst is used, a mixed set is refused), then asks the
image option (Brightness default) or the underlay option (last used), with
value prompts that offer the image's own value or the session's last
underlay fade/contrast, and Monochrome Yes/No. Invalid values re-prompt.
One undo step. -IMAGEADJUST, PDFADJUST, DWFADJUST and DGNADJUST take one
kind each. Raster image Brightness/Contrast/Fade move to an Image Adjust
section as whole numbers with 0-100 validation.
