ACIS text files come in one object per body (3DSOLID, REGION or SURFACE).
STEP B-rep models become a block per product with component inserts at
their placements, scaled to the drawing's units; IGES manifold solids come
in as 3DSOLIDs scaled to the drawing's units with their colours. Splines
that are exactly analytic shapes are kept as those shapes. Windows
metafiles become a WMF<n> block of polylines and text fitted to half the
view, placed at its top-left corner or by WMFIN's insertion prompts. The
Import File window lists the four formats as supported.

The DGN V7/V8 readers expose each element (level, symbology, geometry,

TEXT and MTEXT objects are merged into one MTEXT (top-down or in
selection order, word-wrapped or one paragraph per object, with the
original pitch kept as line spacing) or each TEXT and MTEXT line becomes
an MTEXT of its own. The SEttings option opens the Combine Text settings

PDFIMPORT follows FILEDIA and -PDFIMPORT asks for the file, page,
insertion point, scale and rotation on the command line. A page with a

that trace arcs, circles and ellipses, and runs of circular Bezier arcs
on one circle, become those objects; other Bezier curves become one

Live changes are taken back quietly before Apply, OK or Sync write the

BATTMAN and ATTMAN open a manager for the attribute definitions of one
attributed block: block chips with reference counts and a pick button,
a table whose columns are chosen with chips, move up/down, remove, and
an edit card (Attribute / Text / Properties) for the selected row. Apply,
OK and Sync write the list back to the block definition and, when asked,
rebuild the existing references keeping values through tag renames;
each is one undo step. Live changes are taken back on Cancel. Automation
gains attman_dialog.

The name card draws the selected objects, or the existing definition the
name picks. OK with no objects shows an in-window band offering to select
objects or to define an empty block. A switch opens the new block in the
block editor once it is defined; it is remembered with the other dialog
choices. Automation gains block_def_dialog.

The Block Definition panel's Create Block is a split button listing

A code the reference shows on two buttons runs the button whose command
the reference runs for it (VC runs Viewport Configuration), decided by
the code table's order. Labels, combo values and panel titles report
their bounds while key tips are open, and each code takes the first
spot nearest the reference place that covers none of them nor another
code; a collapsed panel's title is measured to place its code beside
the words.

The count line now uses the objects the selection step itself picked
(a click, a window or crossing, a lasso, a fence, Last / Previous /
All): "N found (D duplicate), M total" when some were chosen already,
"N found, R removed, M total" in remove mode, "N found, M total" when a
removal picks objects that were not chosen.

Quick-access buttons take the numbers the reference toolbar gives the
same buttons (Print 6, Undo 7, Redo 8). Codes the reference shows on two
buttons appear on both, the first in ribbon order running. Codes sit
where the reference puts them: under tab and large-button labels, on a
large dropdown's arrow strip, with their corner at the icon's centre on
icon buttons, and centred on panel titles and the corner launcher; a
button code a panel code would cover rises clear of it.

Every pick during object selection prints the reference's count line:
"N found" for the first pick or a pick that adds nothing, "N found,
M total" after it, "N found, N removed, M total" when objects leave the
set. It is printed before a command's own filtering, so "N were filtered
out" follows it. COUNT reports through it and the ad hoc
"object(s) found." / "object(s) added to selection." lines are gone.

During in-place reference editing everything outside the working set
fades by XFADECTL. A DWF underlay's page now stays as it is, like a
raster image or a PDF page, and only its frame fades; a DGN underlay's
content keeps fading with the rest.

A reference's layer 0 and Defpoints are not dependent symbols: its
objects on them use the host's layers of those names, which are made
from the reference's only when the host has none. Before, they became
XREF|0 / XREF|Defpoints on load and XREF$0$0 on bind.

Picking nested objects reports what each pick added ("1 entity added",
"0 entities added" for an object already in the set), a pick on empty
space starts a window ("Specify opposite corner:"; a window dragged to
the right takes the objects inside it, to the left those it touches),
and a typed point picks the object it lies on. From the Reference Edit
dialog the item count is printed when the session opens, followed by
"Use REFCLOSE or the Refedit toolbar to end reference editing session."

A lone Alt shows a code on every ribbon tab and quick-access button.
Typing a tab code opens the tab and shows the codes of its buttons,
dropdowns, slide-outs and collapsed panels; a button code runs it, a
dropdown or slide-out code opens it and shows its item codes, Esc goes
back one level. Codes follow the reference ribbon; buttons without a
reference counterpart get none and unnamed menu items are numbered.
Codes are drawn as accent pills over the widgets that reported their
bounds in the current frame, with a hint bar under the ribbon. While
the tips are open keys go to them only. The automation gets a keytips
action and read operation.

The right-edge toolbar of a REFEDIT session now shows the definition
being edited (REFEDITNAME) as an accent pill with the number of objects
in the working set, Add to / Remove from Working Set buttons with their
own icons (REFSET Add / Remove, straight to object selection), and
Save / Discard in a separate group below a rule.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
REFEDIT opens a dialog after the pick: the nesting chain as chips with a
preview of the chosen definition, all objects or picking them in the
drawing, attribute definitions (offered only when the definition has
them), locking objects outside the working set and unique names for an
external reference's named objects. The settings are remembered.
With unique names an xref's dependent layers, linetypes, text styles and
blocks are checked out as $N$NAME records of their own; without, under
the plain name, sharing a host record of that name. Save writes them back
under the reference's names, and the records made for the session are
removed when it closes. -REFEDIT uses the remembered settings.

IMAGEADJUST (alias IAD) takes the selected raster images or asks
"Select image(s):", then opens a dialog with a before/after preview of
the first image and brightness, contrast and fade rows (bar plus
stepper, whole numbers 0-100). Apply writes the values to every chosen
image as one undo step; restore defaults sets 50/50/0. Adds the
image_adjust automation action and the image-adjust locale group.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.

- A layout opens for the first time when its page setup was never
initialized (no paper size, no media name) or it was created in this
session; its page setup is initialized then, and with
LAYOUTCREATEVIEWPORT it gets its first viewport. A layout never opened
is saved with an uninitialized page setup and no viewports, so it gets
its viewport when the file is opened again, here or in the reference.
- Select Viewport for view: a viewport is selected when the pick box
(PICKBOX pixels at the sheet's zoom) touches its frame; a pick well
inside or outside selects nothing and the prompt repeats.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- 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

Measured against the reference: a two-colour gradient reaches its end

The rotation is stored in degrees and turns the bottom-to-top direction
counter-clockwise, measured in pixels; a two-colour gradient blends from

Restoring a named view gives the model viewport the view's visual style

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

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 lofted surface's region cross sections are recorded as the curve round

The reference writes none; a draft distance on an extruded surface made

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

A new drawing carries the visual styles the reference's new drawing has

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.
Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
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

- 3D polyline profiles are recorded as wire bodies, like 3D polyline paths.
