Two reports, three defects, all three measured on the running app rather than reasoned about.
"Keyboard focus in drawing tool is broken so that now they are slow and cumbersome." After a
dimensioned entity the bottom-right readout chip — 119x31, borderless, a wxFrame — held the X
input focus. Pressing r produced NO [KEYTRACE] line at all: the key never reached the panel's
CHAR_HOOK. One bare canvas click moved focus back to the main window and the identical key armed
the tool. So every shortcut was dead after every dimension, and the way to get the keyboard back
was to click somewhere harmless. That is the whole of "slow and cumbersome".
Its sibling, the status chip, is a wxPopupWindow for exactly this reason and carries a comment
warning against turning it back into a frame. The readout was left a frame on the premise that
"it appears mid-gesture and the next input is the mouse" — which the measurement falsifies: the
chip keeps the last value on screen after the gesture ends, and a frame that has the focus does
not give it back. It is now a popup too, with the placement and the iconise/deactivate lifecycle
its sibling already needed, because an override-redirect window would otherwise sit on the bare
desktop when the app is minimised.
"Planes hide the bed." Literally true, twice over. The reference planes were half-extent 0.6 *
the bed's larger side — a square 1.2x the plate — and all three are drawn with depth testing
off, so they painted over the plate grid from edge to edge. 0.3 puts them inside the bed, which
is also the Onshape look the size was reaching for: a modest square at the origin, not a
tablecloth.
And the other half was mine. 3f52166e32 muted the bed for the duration of a sketch, on the
argument that a plate grid and a sketch grid are the same visual language. The argument is right
and the call was wrong, because there IS no sketch grid to take over. Pick XY, arm Line, and the
viewport was an empty grey field: no bed, no grid, no origin, nothing to judge a length or a
direction against. The plate grid was carrying the ground reference for the whole tab. The banner
already says where you are; taking the floor away as well only made the sketch harder to draw.
The Bed checkbox is the one thing that governs the bed, in every mode.
Verified on behemoth :10 with the rebuilt binary: focus after a dimension chain is the main
window, r arms Rectangle with no click in between, and the plate grid is under the sketch.

Measured on the running app, not deduced. After a queued dimension chain the value field's frame
is left MAPPED on purpose (mutter refuses keyboard focus to a re-mapped window), so there is a
window in which m_open is already false and the frame is still on screen holding the X input
focus. GTK meanwhile reports that window inactive and routes nothing into the text control. Every
key then lands somewhere that cannot use it and will not give it back:
[KEYTRACE] key=27 ui_mode=1 inline_busy=0 <- the last key the panel ever sees
=== MARK press Delete === <- no trace line at all
xdotool getwindowfocus -> 0xe00404 86x60 <- the value field, still mapped
Delete, Esc and typing all read as dead, which is exactly the report. And nothing could recover
it: close(), cancel() and do_cancel() all return early on !m_open, so the one window still
receiving keystrokes was also the one window no code could dismiss.
is_mapped() asks the question the flag cannot answer, and dismiss() tears the frame down with no
m_open guard, since m_open is precisely what lies in this state. Esc inside the field falls back
to it — while the frame holds focus that handler is the only code the keyboard can still reach,
so if it refuses, nothing else gets a turn. Every close now hands focus back to the canvas
explicitly, because hiding a window does not move the X input focus off it. And inline_busy()
reports the union of "a value is pending" and "a frame is mapped", so Esc routes to the field
whenever one is on screen at all.

Three cues, because one is missed. A teal banner across the top of the viewport names the session
("Editing: Sketch N") and where its exits are; the printer bed is muted for the duration, since a
plate grid and a sketch grid are the same visual language and reading one as the other is how a
sketch gets drawn against the wrong reference; and N looks straight down the plane normal at the
current zoom, with the plane's own y axis as up, because no hand-orbit lands exactly square and a
sketch read at an angle is one whose right angles do not look like right angles.
The banner is an INDICATOR. Finish and Cancel stay on the single ribbon action bar — the tab had
three competing confirm surfaces once and that is not being reopened for a strip of colour. It
sits above the canvas rather than floating inside it: a child window over a wxGLCanvas is a native
window on GTK with no reliable stacking over GL, and being unmissable beats being clever.
The bed checkbox stays the stored preference and is restored on leaving the sketch; ticking it
mid-sketch still shows the bed, because that is a deliberate act and this is only a default.

Two presses used to discard a live sketch. The key was answered in four places that could not
see each other — the inline value field, a sketch branch, a feature-card branch, and the canvas
— so a press aimed at one fell through to the next, and request_exit() carried a fourth layer
that deliberately let the SECOND consecutive press through to cancel_sketch(). The warning it
showed first did not help: the two presses are never one decision, the first is aimed at a field
or a tool and the second at whatever was underneath it.
The stack is now explicit. CadLevel (DesignInteraction.hpp) is four levels deep, the enum value
IS the LIFO depth, and cad_escape_level() is a constexpr function over a POD of four booleans —
so the ordering that is the entire contract is checked by static_assert at compile time, with no
window, GL context or event loop. DesignPanel::escape() acts on the one level escape_level()
names and on no other, and every Esc in the tab routes through it.
The destructive layer is gone from request_exit() itself rather than guarded at its callers, so
the guarantee cannot be re-opened by adding a route: a session holding geometry is left only
through Finish (keep) or Cancel (discard). Cancel now asks before discarding — it used to refuse
and tell the user to press the button they had just pressed, which meant a drawn sketch could be
kept but never thrown away.
Right-click also stops rewarding navigation with a menu: the offer needs BOTH budgets, released
within 200 ms and moved no more than 3 px, and the raycast uses the press position, so the menu
describes what was pointed at rather than where the camera stopped. Two budgets because drift
alone still popped a menu at the end of a slow, careful orbit.
docs/ux/interaction-model.md carries the state machine, the routing and the transition table.

* Fix incorrect early exit for CLI mode no-support preventing parameters from being read
* Use PartPlate's m_height to allow CLI to perform proper BuildVolume check
* Add safeguard against extruder_pintable_heights and extruder_areas vector size mismatch
* Preserve printable_height precision in PartPlate/PartPlateList
* Fixed multiple BuildVolume warning issue, and keep check_outside diff minimal
Refresh detach-from-parent checkbox state
Allow the detach checkbox toggle event to propagate to the custom CheckBox control so it refreshes its bitmap after the value changes.
Tommaso asked the question that names the real defect: if the sketch was open, why was
the same sketch shaded closed and offered for extrude? Because the two halves used
different tolerances. region_loops shades a region closed at 1e-3 mm; connected_loop
chained at 1e-3; the kernel welded at 1e-4 and OCCT matched vertices at 1e-7. The
2.28e-5 mm gap in the reported sketch did not cause that disagreement, it only made it
visible — and fixing the gap alone would have left the contradiction in place, ready to
reappear anywhere in (1e-4, 1e-3].
kSketchJoinTol now lives in SketchEngine.hpp and is the only place the number exists.
region_loops, loop_report, connected_loop and entities_to_wires all read it through
sketch_join_tol(). The viewport cannot promise a region the kernel refuses to build.
The welding is optional, because a kernel that silently closes loops should let you say
no: "Auto-close sketch loops" in Preferences, default ON, no restart. OFF means only
exactly coincident endpoints join — and since both halves read the same value, the
viewport simply stops shading the region closed, so an open loop is visible rather than
welded behind your back. No separate UI needed for that; it falls out of sharing one
number.
Details that matter. The kernel defaults to auto-close ON independently of the GUI, so
headless and MCP callers behave like the viewport instead of inheriting an unset
preference. With the tolerance at 0 the comparisons become <=, because OFF must mean
exact, not broken. OCCT never receives a zero vertex tolerance — it is clamped to
Precision::Confusion.
The preference is pushed from EVERY entry that starts a sketch session, not just
begin(): a Constrain session enters through begin_constrain / begin_constrain_entities
and uses region_loops and connected_loop, so a single push site would have left those
sessions running on whatever the previous one set. begin_imported_transform is excluded
deliberately — it works on imported regions, not chained entities.
Tests: a loop with one joint open by 9e-4 mm, given out of traversal order, builds a
closed four-edge wire; with auto-close off the same loop yields no wire; and an exactly
closed loop still builds with auto-close off, proving OFF means exact. Kernel 66104
assertions / 606 cases green.

* build: enable /Zc:lambda for MSVC
MSVC keeps its legacy lambda processor under /std:c++17, which rejects
reading a constexpr constant inside a lambda that does not capture it
(C3493). No other compiler requires that capture, and clang reports it as
an unused one, so the two cannot both be satisfied without the flag.
/Zc:lambda selects the conforming lambda parser that clang and GCC
already use. It is implied by /std:c++20 and /permissive-, so it is only
needed while we are on C++17. clang-cl is conforming already and does not
take the flag.
It requires VS2019 16.8, so build_release_vs.bat now says 16.8+.
* build: clear 237 unused lambda capture warnings
236 captures across 81 files, 142 of them `this`. Removing an unused
capture changes no behavior; clang does not report a capture whose type
has a non-trivial destructor, so nothing held only to extend an object's
lifetime is in this set.
Nine of them are the second half of the warning, "is not required to be
captured for this use", where the capture is a const or constexpr value
the body does read. Those depend on the /Zc:lambda change in the previous
commit. One of them, in FillRectilinear.cpp, had been worked around with
an #ifndef __APPLE__ guard around the capture list, which is now gone.
GUI_ObjectTableSettings.cpp captured its reset button only to read it
inside #ifdef __WXOSX_MAC__. That branch now takes the button from the
event it is already handling.
* build: fail configure on MSVC older than 19.28 instead of dropping /Zc:lambda
cl.exe answers an unrecognized /Zc: sub-option with warning D9002 and keeps
going, so on VS2019 before 16.8 the flag is silently ignored and the build
instead dies with C3493 in FillRectilinear.cpp, nowhere near the cause.
* fix: delete three locals that are now unused
Their only remaining use was the lambda capture this branch removed. The
Clang builds set -Wno-unused-variable, so the build never flagged them.

The rows, their ✗ buttons and the click-to-highlight were all built against
m_doc.features[m_constrain_feat].entity_constraints — a COMMITTED feature. A live sketch
has no committed feature, so the card was hidden for the whole session and the list it
would have shown was empty by construction. Every constraint applied while drawing was
nameless: the badge said one existed, nothing said which.
rebuild_constraint_list now picks its source by scope. live_constraint_scope() is the same
discriminator apply_constraint already used to route to apply_live_constraint — both
Constrain modes set m_active, so is_sketching() alone would claim the live scope while the
committed manager is open. delete_constraint and highlight_constraint_entities branch on
it too, and the card shows in Sketch mode as well as Constrain.
Keeping the rows in step needed a signal that did not exist: on_solve_state fires on every
frame of a drag, so rebuilding from it would rebuild the list continuously. The tool now
fires on_constraints_changed only when the constraint SET changes — one added by
try_add_constraints, one removed by remove_constraint (the indexed form the badge click and
the ✗ row now share).
The rebuild is deferred through CallAfter. One of its callers is the ✗ button's own click
handler, and rebuild_constraint_list destroys those buttons: deleting the window whose
handler is still on the stack is a use-after-free.

A glyph reads as decoration until something says otherwise, so the badges shipped
last commit were discoverable only by accident. Two places now say it, chosen because
they are where the eye already is:
- the moment of applying, which is the one the user is watching ("Applied constraint ·
its badge is on the sketch — click the badge to remove it"). The hint line could not
carry this alone: it only refreshes when the (mode, step, picks) tuple changes, and
applying a constraint changes none of them.
- the Select-mode hint line, appended only while the live sketch actually holds a
constraint, so it never advertises a badge that is not on screen.
Also fixes what the previous commit got wrong: remove_constraint_near solved through
solve_sketch_entities directly, which relaxes the geometry but leaves m_dof and the
per-entity conflict flags untouched and never fires on_solve_state. Deleting a
constraint therefore left the DoF readout describing the system as it was BEFORE the
deletion, and any red over-constrained tint stranded on screen. It goes through
resolve_live() now, the same path every other live edit uses.

The constraint badges existed and had never once been drawn where they were needed.
build_constraint_glyphs read m_constrain_cons, a vector only the COMMITTED-feature
Constrain mode fills, and the draw call sat inside `if (m_mode == Mode::Constrain)`.
Every constraint applied during a live sketch — which is the path the Constrain buttons
take while drawing, the one added in "Constrain while you sketch" — went into
m_constraints and was rendered by nothing. You could not see that Parallel had applied,
so "nothing happens" was indistinguishable from "applied and invisible".
The glyph builder now takes its constraint list as a parameter: Constrain mode passes
m_constrain_cons as before, the live session passes its own m_constraints. Same glyphs,
same teal.
Seeing them is half of it. A constraint's entire state is exists / does not exist, so the
toggle is a delete, and there was no way to reach one during a session — the ✗ rows in
the panel list are bound to the committed feature. Each badge now records where it landed
(m_glyph_hits) and a plain left click in Select mode within its cell drops that constraint
and re-solves. Shift/Ctrl clicks are left alone so multi-select still works.

Two reports, one root: the sketch tab could not show what was selected.
The bed grid landed last commit, and selection was painted pure white — a freshly
drawn line is auto-selected by the creation tool, so the first thing a new line did
was disappear into the grid. Selection now wears design_selection_color(), the same
cyan a picked solid already wears. White is kept for the hover handle alone.
That invisibility is also why "I apply Parallel and NOTHING HAPPENS": drawing two
lines leaves exactly ONE selected (the last), Parallel needs two, so the planner
correctly refused — but the status text named only the requirement, never the current
pick, which reads as a dead button. It now reports how many are selected and how to
pick the second.

In CAD the centre IS the sketch origin -- GLCanvas3D already moves the axis
triad there for exactly that reason. The grid under it did not agree: it comes
from PartPlate::calc_gridlines, generated from m_origin, the plate's front-left
corner, with an adaptive step meant for a print bed.
Measured on a screenshot from the user's machine: the nearest grid line was 10 px
from the origin in a 23 px pitch. The origin floated mid-cell, in both axes.
Corner-origin is CORRECT for Prepare -- a print bed starts at a corner -- and the
plate list is SHARED with the plater, so re-centring it there would change the
bed for every user of the app to fix one tab. The seam used instead already
existed: _render_platelist takes show_grid, and m_axes_at_bed_center is already
the "this is the Design canvas" flag. The Design canvas suppresses the plate's
grid and draws its own.
Minor every 10 mm, major every 50 mm, both generated from bed_center() so a line
passes exactly THROUGH the origin in each axis. Two GLModels, rebuilt only when
the bed shape changes, not per frame.
White majors, grey minors, the SAME in both themes. There is no white bed to
vanish against: the plate is dark grey either way (DEFAULT_MODEL_COLOR
{0.326,0.337,0.337} light, DEFAULT_MODEL_COLOR_DARK {0.255,0.255,0.283} dark),
a difference of 0.07. An earlier draft inverted the palette on the light theme;
that was a branch buying nothing. For contrast with what this replaces: the
plate's grid draws BOTH its thin and bold families in one 0.43 grey, which is
most of why the stock grid reads as a flat mesh with no scale to it.
z = -0.26, the same value as PartPlate::GROUND_Z_GRIDLINE -- below the bed fill
at -0.03, above the bed model at -0.41, so no z-fighting. Matched by
construction, since that constant is file-static in another TU.
Known limit, commented: the grid is clipped to the bed's BOUNDING BOX, not its
polygon. Identical on a rectangular bed; on a circular one it would spill past
the round edge. The target printers are rectangular.
Verified on the rig, not just compiled: white majors over a fine grey mesh, and
a white line through the origin in both axes.

Five defects from ten minutes of real use, and the mode split behind the worst
of them. One commit because the changes overlap in the same functions; the
pieces are separable in the diff, not in the file.
CONSTRAINING NO LONGER NEEDS A COMMITTED SKETCH. A constraint could only be
applied by committing the sketch, selecting it in the feature tree, pressing the
padlock, and only then picking. While drawing, the CONSTRAIN toolbar was not even
on screen (set_ui_mode showed it in UiMode::Constrain alone) and apply_constraint
answered "Press Constrain on a sketch first" -- in a status line nobody looks at.
Draw two lines, press Parallel, get nothing: that is what a user reported as "the
UX is a mess", and they were right.
apply_constraint now takes the live session first, reading the picks from the
selection model the sketch tool already had (click, ctrl-click to extend,
double-click for the loop) and applying through try_add_constraints, which
already did append -> solve -> keep-or-rollback. The committed Constrain path
stays for editing an old sketch; it is no longer the only way in. The twenty
constraint buttons now show in Sketch mode as well.
The discriminator is is_sketching() && !is_constraining() &&
!is_constraining_entities(). Both begin_constrain and begin_constrain_entities
set m_active, so is_sketching() alone is true DURING a constrain session and the
new path would hijack the old one -- compiling perfectly and failing in
behaviour.
ONE PLANNER, NOT TWO. A second caller meant duplicating the logic that decides
whether a constraint is legal, which roles it binds and whether it needs a typed
value. That duplication is how today's Coincident bug survived: fixed in one
branch, alive in the next one down. plan_entity_constraint() now lives in the
kernel -- pure, no wx, no translation -- and both UI paths call it. DesignPanel
loses 304 lines and gains 155.
Being in the kernel makes it TESTABLE. The Parallel defect existed because a
constraint type met an entity type nobody had tried, and the only instrument was
a 13-minute GUI ladder. 19 new kernel cases cover the matrix: 264 -> 283 cases,
7648 -> 7867 assertions.
Parallel, Perpendicular and EqualLength gain the two-line guard they never had.
On non-lines they used to emit a def the solver silently dropped -- the sketch
reported itself constrained when it was not, the same class as Horizontal on a
Point. EqualLength on two rounds still promotes to EqualRadius first.
Symmetric is planned completely, including its axis pick: the plan carries a
VECTOR of defs because Symmetric on two lines is two constraints (P0/P0 and
P1/P1). A single def would have half-applied it -- one end pinned, one free,
looking correct until something moves.
A PLACED POINT SURVIVES THE COMMIT. Type::Point was created correctly and never
drawn once committed: both renderers skip it, correctly, since entity_polyline
gives a point nothing. What was missing is the vertex-marker path the live
session already used. rung_point passed throughout because it asserts the
document, and the point was always in the document -- the pixels lied.
ESC STOPS EATING AN UNSAVED SKETCH. The third press reached cancel_sketch(),
clearing m_entities with no warning and nothing to undo. live_sketch_has_work()
existed and was never consulted. The exit layer refuses once when there is work
and lets a second consecutive Esc through; the refusal re-arms on a button press,
never on mouse motion, or Esc could never exit while the hand moves.
TWO NEW RUNGS. D10 drives Parallel through the committed path -- it passes on
the PRE-fix binary, which is how we know the user's failure was the mode and not
the constraint. D11 is the acceptance for the collapse: draw, pick both, press
Parallel, no commit and no padlock. Ladder 126 -> 135 properties, all holding.
CON_BTN_SKETCH is measured, not derived: in Sketch mode the group renders after
the sketch toolbar, so the first button is at 677, not 449. Pitch 42, twenty
buttons, read off a screenshot. Deriving it by offset is how that table drifted
the last time.
Known limit, commented at the call site: a constraint added to a LIVE sketch is
not on the document undo stack, so Ctrl+Z will not take it back until the sketch
is committed.

PartPlate::store_to_3mf_structure read first_layer_time from the indirect cali_bboxes_data struct,
which the GUI populates at Plater.cpp:10600 but the CLI never writes to. The result was uninitialized
memory leaking into slice_info.config
Read directly from get_slice_result()->initial_layer_time, which is populated by
GCodeProcessor::finalize() in both code paths and matches the pattern already used a few lines
above for gcode_prediction.
Also default-initialize PlateBBoxData::first_layer_time to 0.0f as a defense against any other consumer
reading it without an explicit write.
build: clear 54 dead private fields
54 of the 161 -Wunused-private-field warnings, across 31 files. These are
the ones needing no judgment. Each member is declared once and appears
nowhere else in src/, counting the .mm and .c sources as well as .cpp and
.hpp, so nothing writes them and nothing reads them. Every removal is a
whole line, and no declaration shares a line with another member.
The remaining 107 are left alone. Those members are mentioned elsewhere,
usually assigned and never read, where the fix might be deleting the
member or might be restoring a read that went missing.
build: clear 53 unused value warnings
49 of them are deliberate i18n markers. L(s) expands to s, so
L("Main Extruder"); is a string literal as a statement and its value is
discarded. The strings have to stay, because the real values come from
printers/*.json at runtime and xgettext cannot scan those. Each block is
now a static const char *const markers[], which uses the values rather
than discarding them. Extraction is unchanged: the xgettext invocation
from scripts/run_gettext.bat gives 76 msgids over the two marker files
before and after, with identical msgid and msgctxt sets.
The other 4 are statements with no effect. AMSItem.cpp:117 and :174
construct and drop a wxColour(255, 255, 255); AMS_TRAY_DEFAULT_COL is
that colour, and the line above already assigns it. UpgradePanel.cpp:865
reads a member and drops it.
wgtDeviceNozzleSelect.cpp:269 writes
if (item; auto ptr = m_nozzle_rack.lock()), which puts the null check in
the init-statement position where its value is discarded, so the check
never runs, and sGetNozzlePosId then dereferences item. Nothing reaches
that today, because the only sender of the event sets itself as the
event object and the dynamic_cast always succeeds. The check now runs.
Port of snaporca da8d011b87; parity holds (DesignPanel.cpp still exactly 32 divergent
lines). Verified independently on this fork's own rig: full ladder 126/126 against
BuildID 96c697a3, built from this tree.
Reviewing the DistanceX/Y fix for OTHER members of its class found three more live defects
on the constrain toolbar. All four share one root: a branch assumes every picked entity has
two endpoints, and the solver's refusal to resolve a role it cannot find is silent.
COINCIDENT had the identical closest-pair walk over {P0,p0},{P1,p1}. For two Points the
phantom (0,0) pair sits at distance 0, which is the smallest distance there is, so it
ALWAYS won: ptOf(Point,P1) -> 0, ref_ok fails (SketchSolver.cpp:185), constraint dropped.
Not sometimes -- every press.
HORIZONTAL/VERTICAL hardcoded ra=P0, rb=P1 with no type check. With a Point picked the
constraint is dropped by the same mechanism but still STORED: constraints goes 0 -> 1 after
the commit and nothing moves, so the Constraints list shows a dimension that can never do
anything. Worse than refusing -- the panel claims the sketch is constrained when it is not.
ANGLE computed p1-p0 on whatever was picked. On a circle that is (0,0)-centre, so two
circles pre-filled the field with the angle between their centre POSITION VECTORS (178.83
deg for two on the x axis), and accepting it emits SLVS_C_ANGLE on two circle prims.
Both branches now refuse with a message. entity_ends()/closest_ends() are file-scope and
shared by Coincident and DistanceX/Y, so there is one implementation instead of two that
drift.
Two smaller findings from the same review: infer_auto_constraints' roles_of omitted
EllipseArc while heal_coincidences' identical copy has it; and set_point(Circle, Center)
wrote e.center and not e.p0, breaking the "p0 mirrors centre" invariant for the duration of
a live drag.
New rungs D8 and D9, both RED against the shipped binary and green here.

The Design tab's viewport is the fourth GLCanvas3D on the shared GL context and
the only one the plater does not own, so unbind_canvas_event_handlers() and
reset_canvas_volumes() never reached it — the macOS Command+Q and Debian cases
those calls exist for. Its frame-level handlers become members so they can be
unbound.
The bind sat above GLCanvas3D::bind_event_handlers(), and on_size never Skips,
so wx's reverse-order dispatch stopped before it and the handler never ran.
