DCFORM sets the annotational or dynamic form and continues into the
DIMCONSTRAINT option prompt, whose wording and last-used default match the
reference. -PARAMETERS manages parameters from the command line; a
double-clicked constraint dimension opens its value prompt. Dynamic
dimensions rescale on every camera change and their display overrides stay
out of the saved file. A driving dimension between an entity's own ends no
longer has its length retained, so a new value moves the second point along
the dimension axis; parameter edits hold the first constraint point.

The dynamic dimension of a dimensional constraint is now linked in the
drawing file (AcDbAssocDependency + AcDbAssocDimDependencyBody on the
constraint node), reread on load, hidden by DCHIDE/DYNCONSTRAINTDISPLAY
and never plotted; it carries a lock mark before its text. New
CONSTRAINTNAMEFORMAT and DYNCONSTRAINTDISPLAY variables and the
DIMCONSTRAINT option front end. A transformed entity whose own end points
a driving dimension measures keeps only the first constraint point, so a
scaled line returns to its dimension value.

DCLINEAR, DCHORIZONTAL, DCVERTICAL and DCALIGNED follow the reference flow:
`Specify first constraint point or [Object] <Object>:`, `Specify second
constraint point:`, `Specify dimension line location:`, then `Dimension
text = …` and `Enter value or name and value <d1=100>:`. Linear reads
horizontal or vertical from the dimension line location the way a linear
dimension does; Object takes a line's, an arc's or a polyline segment's
ends. A miss reports `No valid constraint point found.` / `No object
found.` and asks again; another object type reports `Invalid selection for
Linear. Select a line, polyline segment or arc.`.
Each constraint creates a drawing parameter (`d1`, `d2`, …, or the typed
`name=expression`), drives the constraint through it, and draws a dynamic
dimension in constraint gray whose text follows CONSTRAINTNAMEFORMAT
(`d1=100.0000`); the dimension is associated with the constrained objects
and its text is refreshed after every solve. A typed value other than the
measured one moves the second point while the first stays, and so does a
later parameter edit. Deleting the constraint removes its dimension and,
when nothing else reads it, its parameter.

Equal was applied through a generic gather-then-apply flow and, with the
default size-retaining solve mode, never changed anything: the solver
held both sizes and the relation could not be met. Now:
- GCEQUAL joins ECONSTRAINT and GEOMCONSTRAINT Equal; both objects are
picked inside the command (`Select first object or [Multiple]:`,
`Select second object:`; Multiple gathers `Select objects to make equal
to the first:`), a selection made beforehand is not used, a miss says
`No object found.` and re-asks, an unsupported object or the same object
twice is reported and re-asked, a repeat is refused.
- The follower is resized in place before the relation is added: a line or
straight polyline segment keeps its start and direction and its end
moves to the first object's length; a circle or arc keeps its center and
takes the radius.
- During edits the side that is not being edited follows the same rule:
its size is not retained, its start (or center) and other vertices are
held and its direction kept, so only its length or radius changes; a
chain of Equal relations follows along.

Follow-up to #1341:
- interactive UCS offers Face / OBject; bare UCS OBJECT starts an entity pick
- one UcsPickCommand serves both FACE and OBJECT
- ucs_from_normal calls the existing arbitrary-axis helper instead of a copy
- prompt catalogue key and en-US text follow the new option list

The plot dialog asks CUPS printers for their sheets and margins; on Windows
the query was a stub, so every printer showed the paper catalogue with
unverified margins. The driver is now asked the way the plot dialog expects:
- windows_media (compiled and tested everywhere): the three parallel
DeviceCapabilities tables (ids, sizes in tenths of a millimetre, 64-WCHAR
names) become one PrinterMedia per distinct size — a rotated or
borderless twin folds onto its sheet, catalogue sheets keep their name,
unknown sizes carry the driver's — with the device's margins on every
entry and the driver's default sheet found by id or by user size.
- print_to_printer (Windows): DeviceCapabilitiesW for the tables, the
default DEVMODE for the default sheet, one portrait printer DC for the
unprintable margins (physical offsets and extents, per device — a
documented approximation). The DEVMODE fetch is shared with the print
path (with_printer_devmode).
- A direct print now asks the driver for the plot's own sheet (by id, or
as a user-defined size), so an A3 plot prints on A3 rather than shrunk
into the driver's default; a driver that refuses the sheet is asked for
the orientation alone.
- The capability cache remembers printers that could not be asked, so a
slow failing query runs once per session, not on every dialog open.
- PRINTERS <name> reports a printer's sheets, margins and default sheet.
Tests: names (NUL trim, full slot, lossy), media folding and dropping,
default by id / user size / none, DC margins, paper id lookup.

1) VCONSTRAINT (and the new GCVERTICAL name) uses the axis constraint flow:
"Select an object or [2Points] <2Points>:", 2Points mode with the
reference's re-prompts and messages, and the same object types as
Horizontal — line, polyline segment, text, MText, ellipse axis.
2) Object mode turns the object about its first vertex; a two-point relation
across two objects slides the second object rigidly onto the axis.
3) Re-applying an axis constraint reports that the constraint already
exists; Vertical follows the UCS Y direction.
4) The constraint bar draws Vertical as the reference's axis mark, with the
point marker for a two-point relation.

On Windows a plot with no printer chosen went to the PDF application's
bare "print" verb — whatever that application considered its default —
and a viewer without a "printto" verb (Edge, store readers) silently
dropped the printer the dialog had chosen. The dialog also never named the
system default, and a failed printer enumeration left only "Default" and
"PDF" with the reason written to a console nobody sees.
- The default printer is looked up by name (GetDefaultPrinterW) both for
the dialog's "System default printer (…)" entry and before every job.
- A pure route decision (plan_print_route) resolves "Default" to that
name and uses the PDF application only when it registered a "printto"
verb for .pdf (AssocQueryStringW); otherwise the job goes straight to
the spooler through the existing GDI path. The report says which:
"Sent to printer: NAME (direct print | via the PDF application)".
- list_printers reports the system's own error; the plot dialog shows it
under the printer row and the command line warns once. A desktop without
CUPS is an empty list, not an error.
- PRINTERS command: default printer, listed printers (or the error) and,
on Windows, the print route — a report to paste into an issue.
- Properties… on the Default entry opens that printer's preferences sheet.
- GDI path: the driver's dmSize is kept (its private data lives behind
it), the print raster is no longer memoised for the session, and a
spooled temporary PDF is removed.
Tests: route planning (named / blank / no default / printto or not), the
PRINTERS command; the two Windows-only GDI tests pass the resolved name.

1) FXCONSTRAINT (and the new GCFIX name) prompts "Select point or [Object]
<Object>:" — a pick fixes that constraint point; Enter or O asks for one
line, polyline segment, circle, arc, ellipse or spline; misses and
unsupported objects report the reference messages and re-prompt.
2) Point, block, text, MText, attribute and table insertion points are
addressable constraint points.
3) Re-applying Fixed to the same point or object reports that the constraint
already exists instead of adding a duplicate.
4) A persistent Fixed holds its pre-edit geometry through MOVE, ROTATE,
SCALE, STRETCH, grip and Properties edits: fixed points stay, free points
of a partly fixed entity follow the edit, and size retention skips fixed
entities.
5) Object mode on a polyline fixes the picked segment (natively persisted)
instead of the whole polyline; arc segments pin endpoints, center and
radius.
6) Ribbon label "Fix" with a padlock icon.

- PSETUPIN / -PSETUPIN: with no arguments a file picker offers the chosen
drawing's named page setups in the Plot dialog; `PSETUPIN <file>` opens
the same chooser on that file; `PSETUPIN <file> *` or
`PSETUPIN <file> name,name` import straight away. Same-named setups are
replaced, the import is one undo step, and the report counts both.
- The Plot dialog's page-setup list gains "Import…": the chooser shows the
source drawing's setups with a tick each, All, Import and Cancel, and
selects the first imported setup afterwards. The source is read off the
UI thread with the same reader the editor uses for its own setups
(`scene::document_page_setups`), and handles that only meant something
in the source drawing (plot view, visual style) are dropped on import.
- Options → General → Plotting: "Show the page setup for new layouts"
opens the Plot / Page Setup dialog whenever a layout is created
(persisted with the plot preferences).
Tests: the document reader, the command (all / named / unknown / missing
file / undo) against a drawing saved by the app, the chooser flow, and the
new-layout option. Nine new strings in all 21 locales.

Plot dialog:
- "Units" (millimetres / inches) is the page setup's own unit: the offsets
and the custom scale are shown in it, the stored ratio converts with it
so the plotted result and the paper space's unit stay the same
- "Custom: [paper] mm = [drawing] units" spells the picked scale in that
unit and accepts a typed ratio, which selects the list's name for it or
becomes a ratio entry of its own
- "Hide paperspace objects" is the page setup's plot-hidden flag; it is no
longer derived from the "Hidden Line" shade mode
- "Save changes to layout" (paper layouts, on by default) writes the dialog
into the layout when a plot is sent; previews never touch it
- offsets are labelled in the page-setup unit and kept in millimetres in
the file
System variables (typeable, through SETVAR, listed by SETVAR ?):
- PLOTOFFSET, PAPERUPDATE, PLOTROTMODE, PLOTTRANSPARENCYOVERRIDE and
BACKGROUNDPLOT live with the persisted plot preferences: the plot origin
counts from the printable corner unless PLOTOFFSET says the paper edge;
a printer that does not list the sheet either warns or switches to its
default sheet; transparency can be forced on or off; BACKGROUNDPLOT bit 1
is the dialog's background switch and bit 2 drives batch plots
- CTAB and TILEMODE read and switch the current layout
Tests cover every new control and variable; six new strings in all 21
locales; the Plot dialog grows to 940×690 for the two extra rows.

Retaining a line's length added a P2PDistance constraint, whose gradient
divides by the current distance. For a zero-length line the solver got a NaN
Jacobian and its SVD fallback never returned, freezing the editor (e.g.
ECONSTRAINT on a line drawn by clicking one point twice). Hold coincident
endpoints together with per-axis differences instead.
Control-point splines read without knots are given a degree their control
points can carry (at most n - 1) and a clamped knot vector when a drawing
loads. Generating knots for fewer points than the degree underflowed during
DWG write: a panic in debug builds, an unbounded allocation in release, and
reachable from autosave. A lone control point with no knots or fit points is
purged as corrupt.

Right-to-left line reordering walked each atom's byte range and sliced the
line at every byte, panicking when a neutral multi-byte character such as a
guillemet preceded the first strong character. Walk characters instead.
FIND/FINDALL located the REPLACE keyword in a Unicode-uppercased copy and
sliced the original with that offset; uppercasing can change byte length
(dotless i, ligatures). Uppercase ASCII only, which keeps offsets aligned.
FILLET and CHAMFER inline R/D shorthands now test the original text before
slicing past the first character.

The Display page could only take a typed #RRGGBB, which is precise but
no way to choose a colour by eye. The swatches are now buttons that
open a wheel.
The wheel does not replace the hex field, it sits beside it: typing an
exact value stays the quickest way to reproduce a known colour. On
submit it hands a hex string to the existing ModelSpaceBgChanged and
friends rather than writing the config itself, so the two routes
cannot drift apart on validation, persistence, or the MatchTheme
fallback an empty field triggers.
Also stops the Browser shipping in the default dock layout. It was
added to the right edge, which shifted the block palette to index 1
and broke four dock tests that encode the existing arrangement. Those
tests were right and the change was wrong: the earlier commit claimed
to leave the layout alone. BROWSER now docks the panel on first use,
so nobody's edges rearrange on upgrade for a panel they never asked
for.
CREATESKETCH opens a sketch on the current UCS, or on one of the three
origin planes with XY, XZ or YZ. FINISHSKETCH closes it again.
Nothing here is new machinery: the plane is a UCS, the square-on view
is PLAN, the drafting aids are the snapper. What the pair adds is
holding them together and putting them back afterwards, including the
snap master state, so a user who works with snapping off gets that
back rather than silently keeping it.
Squaring the view up is not cosmetic. Drawing on a plane seen nearly
edge-on is the main way geometry lands somewhere the user did not
mean, because a few pixels of cursor travel cover a long way in world
space.
A sketch is a mode rather than a document object, so what it produces
is ordinary model-space geometry and the file stays a DWG other
software can open. Whatever was drawn becomes the Previous selection
set, so EXTRUDE then Previous consumes it without making the user
reselect a profile they just finished.
Draw a profile, extrude it, then sketch on a face of the result: the
operations were all there, but nothing turned a solid's face into the
active drawing plane, so the second half of that loop was unreachable.
UCS FACE takes a surface pick, finds the planar face under it and
builds the plane from the face normal. X comes from the Arbitrary Axis
Algorithm, so the same face always yields the same X axis and a sketch
drawn on it does not spin when the UCS is rebuilt.
UCS OBJECT adopts a planar entity's own stored axes instead of
re-deriving X, so a sketch started from a circle lines up with how
that circle is stored. It reuses the profile extraction EXTRUDE
already runs, which means anything extrudable can also be sketched on.
Bare UCS FACE starts an interactive pick that resolves through the
same inline handler, so the clicked and typed paths cannot diverge.
Comments and the Options help text describe the behaviour of commercial
solutions without naming any product. The command menu puts the command's
keywords directly under Enter / Cancel, with Recent Input and Snap
Overrides below them, so the choices that change from step to step are the
closest to the pointer.

The command menu now follows the commercial solutions' layout row for row: Enter, Cancel,
Recent Input ▸, the command's keywords, Snap Overrides ▸ (every object snap
with its glyph, Mid Between 2 Points, None, Osnap Settings…), then Pan and
Zoom. Pan / Zoom run transparently while a command is active ('PAN,
'ZOOM …): navigation modes leave the command untouched and an interactive
ZOOM Window parks it and resumes it afterwards. Rows carry an icon gutter
so labels align; the Enter row shows a default value ("<0.5000>") as its
hint instead of a second finish row.
ARC gets the commercial solutions' prompt flow with all keywords: start [Center], second
point [Center/End], end; after Center: end [Angle/chord Length]; after
End: center [Angle/Direction/Radius]; Enter continues tangent. The
previous default (Center/Start/End with method codes) stays as ARC_CSE.
Object snaps gain a one-shot "None" override. New strings in all locales.

The viewport context menu is now built from a pure model
(ui::popup::context_menu) rendered by the overlay: while a command runs it
offers Enter / Cancel / every keyword of the command's options() with the
keyword shown as a hint, a Recent Input submenu and M2P; when idle it offers
Repeat, Recent Input, Clipboard, Undo/Redo with history labels, the edit
block (Erase/Move/Copy/Scale/Rotate/Mirror/Draw Order), Isolate, Pan/Zoom,
selection tools, Properties and Options. The default row is anchored under
the pointer and the menu is keyboard-navigable (arrows, Enter, mnemonic
letters; any other key closes it and types into the command line).
Right-click behaviour is a user preference (Options → User Preferences,
SHORTCUTMENU / SHORTCUTMENUDURATION): shortcut menu (commercial solutions default),
time-sensitive, or the previous Enter-first cycle.
LINE gains options() (Close/Undo/eXit).
