* fix: build_win.bat builds with whatever clang-cl is first on PATH
VsDevCmd appends the Visual Studio LLVM directory to the end of PATH, so
a standalone LLVM already on it shadows the Visual Studio one. -l -x
passed a bare clang-cl.exe for CMake to resolve, so the build ran on
whichever copy came first. For one reporter that was an LLVM 11, which
failed the compiler check before anything was compiled:
-- Check for working C compiler: C:/Program Files/LLVM/bin/clang-cl.exe - broken
lld-link: error: undefined symbol: __guard_eh_cont_table
The compiler is now resolved through vswhere and passed as a full path,
so PATH order no longer matters. CMake derives the linker from the
compiler directory, so lld-link follows. Only a configure passes it to
CMake, so -p and --no-configure resolve nothing and stay buildable on a
machine with no clang installed.
When Visual Studio has no clang toolset the script falls back to the
first clang-cl on PATH and names it. With none installed at all it now
errors with what to add, instead of failing later inside CMake. Every
clang-cl run that configures prints the compiler it resolved.
The suite gains a clang-cl fixture earlier on PATH than the Visual
Studio one, and an empty ProgramFiles(x86) to put vswhere out of reach,
which covers both fallbacks without touching the machine.
* fix: build_win.bat pointed at a solution file that is not there
The Visual Studio 2026 generator writes OrcaSlicer.slnx and the releases
before it OrcaSlicer.sln. The summary hard-coded the second, so the path
it printed after an MSVC build against 2026 was wrong.
The sweep now validates each printer with the filament that printer ships, so a run
over every vendor reports what a single-vendor run does. Validator only - no change
to slicing output or shipped profiles.
Revolve failed on a sketch whose profile was closed. Decoding the reported 3mf: four
entities forming a proper closed loop (joints open by 4.44e-06 mm, well inside
tolerance) plus one stray 1.82 mm Line at (-24.2, 80.3), inside the shaded region,
touching nothing.
The viewport's region_loops discards open chains ON PURPOSE — it exists to find
EXTRUDABLE regions — so the user saw one clean closed region. entities_to_wires kept
the stray as its own one-edge loop, so it returned two wires, and Revolve goes through
entities_to_wire which demands exactly one. Extrude would have failed one step later in
wires_to_face, because a one-edge open wire bounds no face. Same class as the tolerance
split fixed in 8b568b7b: the viewport and the kernel disagreeing about the sketch — this
time about what BELONGS to the profile.
entities_to_wires/entities_to_wire/build_sketch_wire take closed_only. It is not a
blanket rule: a SurfaceExtrude builds a sheet FROM an open profile and a Sweep PATH is
normally open, so all ten call sites are classified individually — true for the face
fallback, Extrude-taper, Revolve, the Sweep PROFILE and Loft profiles; false for
SurfaceExtrude/Revolve/Loft/Fill and the Sweep path.
A component counts as open when some welded node has DEGREE 1. The first attempt used
"the traversal did not return to its starting node", which regressed the bridged C
profile: a closed loop that also carries a second edge across the same two nodes has no
free endpoint, but its Eulerian walk ends elsewhere. Degree-1 is the property that
actually distinguishes a stray segment from a closed profile; the suite caught the
difference.
Behaviour change decided by Tommaso: a stray is IGNORED, not refused. The test that
required refusal dates from when ignoring meant falling through to a default rectangle —
geometry nobody drew. That fallback is gone, so ignoring now builds the circle the user
actually drew. Its assertion is updated with the reason.
The bridge round-trip test extruded an ENTIRELY open chain and "worked" only because
OCCT will make a face from an open wire. It gets a genuinely closed profile: the test is
about serialization, and deserialize_recipe recomputes, so the document has to be one
that legitimately builds.
Failures now say WHERE. sketch_open_ends reports free endpoints under the same weld
tolerance the wire build uses, and open_loop_message is shared by both throws, because
Extrude fails through build_sketch_face and Revolve through build_sketch_wire — enriching
only one would have left the commoner path the less informative one.

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.

An extrude built a solid the user never drew: three sides of the handle plus the arc
that bulges outside the outline, with the bowl's second arc and the left edge missing.
Two faults met. entities_to_wires added edges in ENTITY-CREATION order, so a partial
wire rejects the next edge even when the sketch closes perfectly; and one joint of the
reported sketch is open by 2.28e-5 mm, wider than OCCT's 1e-7 vertex tolerance and
wider than this function's own EPS of 1e-6, so that edge was refused on geometry too.
Neither showed up, because BRepLib_MakeWire::Add DROPS a disconnected edge
(BRepLib_DisconnectedWire + NotDone) while every successful Add ends with
BRepLib_WireDone + Done() — overwriting the failure. `if (!wm.IsDone()) return {}`
was therefore asking only whether the LAST edge connected. Six edges in, four out,
IsDone() true.
Endpoints now weld into shared nodes at one tolerance (kSketchWeldTol) used by BOTH
the union-find grouping and the wire build — they disagreed before, which is how a
joint gets united into a loop and then refused by the builder. Each node becomes ONE
TopoDS_Vertex, so the builder matches on identity instead of proximity, with the
vertex tolerance widened because BRepLib_MakeEdge::Init projects a vertex onto the
curve within that tolerance and a welded node sits up to the weld gap off its
neighbour's curve. Members are then walked in traversal order. Finally the result is
counted: IsDone() alone is not evidence, edge_count == members.size() is.
Arc geometry is untouched — the midpoint from (start_angle+end_angle)/2 and the
solver's angle reflow both measured correct and were never part of this.
The regression case carries the reported sketch verbatim, open joint included. It
fails 4 == 6 without the fix, which was measured, not assumed. Kernel 66092
assertions / 604 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.

* fix: prevent heap corruption in model repair with auto-backup
The CGAL model repair (fix_model_with_cgal_gui) runs on a worker thread
that mutates the live ModelObject (split / delete_volume / set_mesh).
Those mutators transitively call save_object_mesh(), which hands the
object to the auto-backup manager. The manager clones and serializes the
object on its own thread via an internal Model documented as "visit only
in main thread". Running that path from the repair worker races the
backup thread on the shared model, causing use-after-free / heap
corruption -- EXC_BAD_ACCESS and libmalloc "corruption of free block"
aborts, always with the "cgal_fix_model" worker on the stack inside
add_object_mesh -> Model::add_object / delete_object.
Wrap the repair in a SaveObjectGaurd so the backup manager ignores the
object for the duration of the repair; a single backup is taken when the
guard is released on the main thread after the worker joins. This mirrors
existing batch-edit usage of SaveObjectGaurd (Model.hpp, GUI_ObjectList).
Repro: repair a multi-part / splittable object with auto-backup enabled
(Preferences > Backup); crashed within a few repairs on macOS arm64.

* build: add build_win.bat, a Windows build script for deps, slicer and toolchain setup
build_release_vs.bat takes no options: what it builds is decided by editing
it. This adds build_win.bat alongside it, with short and long options, a
grouped help message, a dry-run mode that prints every command instead of
running it, and one option per thing a developer actually varies - the
configuration, the architecture, the compiler, the generator, the Visual
Studio release, how much gets rebuilt, and where the dependency tree lives.
It works from any directory, needs no developer command prompt in either
generator mode, and keeps CMake ahead of Strawberry Perl on PATH so a build
does not depend on how the user ordered their environment.
scripts/test_build_win.ps1 covers it with table-driven cases that run the
script under --dry-run and assert on the commands it prints, so nothing is
configured or built. The Windows build jobs wait on that suite.
Based on the script from OrcaSlicer#11097.

* build: report what build_win.bat produced and what to do next
Every successful run now ends with a block naming what it built and the
commands to carry on with. Those commands repeat the flags that reproduce
the run, so a rebuild after a clang-cl Ninja build is not silently an MSVC
one. A failure gets a framed block naming the command that failed and a
retry scoped to the stage that failed, so a slicer error does not suggest
discarding an untouched dependency tree.
Installing is now opt-in behind -i. The install tree is a second full copy
of the build that exists mainly so the release can be zipped from it, while
the build tree is already runnable, with the DLLs beside the binary and
resources symlinked rather than copied.
Configuring against a dependency tree that was never built now names it
instead of failing several hundred lines into CMake's package resolution.
scripts/test_build_win.ps1 covers all of it, and gains -Name so one case
can be run without the full pass.
* build: let the test options stand alone, and say which build things apply to
--run-tests named two things to do and then did neither without -s, so
`build_win.bat -lx --run-tests` answered "Nothing to do". Both test
options now imply the slicer build they cannot happen without, unless
another action was already named, so -d --tests is still a dependency
build. --install-vs has turned on --install-deps the same way all along.
That makes them actions, so they move to the group that says so. -i goes
the other way, to the step toggles beside --no-configure and --no-gettext,
since it does not stand alone and adds a step rather than describing what
kind of build to make. An example shows the tests run with toolchain
flags, because flags pick which build gets tested and a bare --run-tests
would build and test a default tree the developer never asked for.
Two help lines named defaults that were not the defaults. --build-dir said
"instead of build/" and --deps-dir said "instead of deps/", but trees are
named for the configuration, compiler and architecture, so build/ is only
the default for a release x64 MSVC build, and deps/ is the source
directory rather than a tree anything is built in.
The hint for a missing dependency tree now carries the flags that
reproduce the run. It said "Build them with -d", which after a clang build
points at the MSVC tree, so following it left you no better off. Every
other suggestion the script makes already repeats them.
-k counted on the developer to read taskkill invocations as progress. It
now names each image and how many processes it is about to stop, which is
what explains the pause, and skips the ones that are not running instead
of printing taskkill's "not found" as though something had gone wrong. No
image can stop the rest.
The environment example set SLIC3R_ASAN, which -a already does, teaching
the long way round to a flag the script owns. It now sets options that
have no flag. The note under it said "Use these for a value containing
spaces. Ampersands are not supported", which named neither what "these"
were an alternative to nor where ampersands were a problem.
The test harness gains a NotExists field, because output cannot show what
a run did not create, and two cases needed to prove exactly that.

* ci: build the Windows x64 dependencies and slicer with clang-cl
Passes -l -x from the Windows jobs, using the clang-cl and Ninja options
added in #15373. Ninja runs each dependency's build step as a plain command,
so the jobs set up a VC environment for OpenSSL's nmake. arm64 stays on MSVC
for now.
The deps cache key gains the compiler, so windows-x64 becomes
windows-x64-clang and windows-arm64 becomes windows-arm64-msvc.
* deps: select OpenSSL's ARM64 target from DEPS_ARCH
CMAKE_GENERATOR_PLATFORM is only set by -A, which Ninja never receives, so
the Ninja build selected the x64 target on ARM64. DEPS_ARCH is derived from
CMAKE_SYSTEM_PROCESSOR and is already independent of the generator.
* ci: build the Windows ARM64 dependencies and slicer with clang-cl
Three dependencies need handling first. libpng and OpenCV each build an ARM
SIMD path that does not compile with clang-cl, so those paths are off; PNG
already had the same opt-out for Apple ARM. OCCT is built with cl, since
clang-cl cannot emit one of its large generated files and there is no option
to turn that off. All three are gated to Windows ARM64 with clang.
