fix(bed-fit): keep object size and placed bounds apart (#91) by DVOpenLabs · Pull Request #104 · DVOpenLabs/snapmaker-studio

DVOpenLabs · 2026-10-10T00:58:39Z

Stacked on #102 (base is fix/93-repeated-instances, itself stacked on #97). Retarget to main once those merge.

Closes #91

What was wrong

Size-only bed-fit statements used the overall mesh extents. A small object moved off the plate still "fit", and separated objects or plates could add up to a combined extent that produced "scale or split" advice about no single object.

Which consumer uses what

Consumer	Before	Now
`intelligence.project_info` (Design Health)	one overall `dimensions_mm`	keeps `dimensions_mm` (labelled `dimensions_basis: overall_extents_by_size`); with `placement_aware=True` adds `object_sizes_mm` (per object and part, mm), `objects_unmeasured` and `placed` (per instance and plate)
`service.bed_fit` / `bed_fit.py`	overall extents vs bed	each object judged on its own, every size sentence starts "By size"; placement added separately ("By placement"); an off-plate instance makes the result a risk even when every object is small enough
`validation_report` "Fits the print bed"	overall extents	per object, "By size", names the object that is too big
`DesignHealth.tsx`	overall extents	"Bed fit (by size)", per object, "Size only: where it sits on the plate is a separate check."

Multi-plate projects get per-plate extents and no combined extent. When no per-object size can be measured the answer is unknown ("By size, Studio could not measure each object, so it cannot say whether they fit"); it never falls back to the combined extents. Every object is checked (no cap); build items whose object is missing are counted and keep the result from saying everything fits.

Review round 7

One fixture, every consumer: preflight, Ready Now, the Bed-Fit API, the validation report, the overall extents and the scene agree for helper roles including precise_seam_*. Head 20d5228.

Review round 6

Sizes use the same shared role rule (see fix(placement): judge every build item, not every object id (#93) #102): tests through service.bed_fit, the validation report and per-object sizes for each of the four helper roles on a nested assembly, a missing role, conflicting records and a child beneath a modifier. Backend pytest 3281 passed, 49 skipped; desktop tsc, vitest (826) and build clean.

Review round 5

An object's size is the size of the parts that print (a tall modifier no longer makes it too large or too tall); the bed-fit placement findings flag instances below the build plane; stale comments fixed; the big-printer test also drives service.bed_fit through identification. Includes the fix(placement): judge every build item, not every object id (#93) #102 round-5 changes. Documented limit: the zip fingerprint is member name, size and CRC-32 only. Backend pytest 3255 passed, 49 skipped; desktop tsc, vitest (826) and build clean.

Review round 4

A connected printer Studio cannot identify now gives an unavailable bed-fit result (size and placement unknown) instead of using axis travel as a size. An identified printer is checked against its profile volume and labelled as the profile's. The bed-fit placement findings check placed Z (build-item scale included) with the shared over_height rule. Includes the fix(placement): judge every build item, not every object id (#93) #102 round-4 changes. Head below: backend pytest 3248 passed, 49 skipped; desktop tsc, vitest (826) and build clean.

Review round 3

service.bed_fit identifies a connected printer: the U1 (or another profiled printer) is checked against its recorded printable volume, an unidentifiable one keeps a size check and gets no placement verdict. Measurement caches are locked. Includes the fix(placement): judge every build item, not every object id (#93) #102 round-3 changes. Head 54a2274; backend pytest 3243 passed, 49 skipped; desktop tsc, vitest (826) and build clean.

Review round 2

The bed-fit placement check uses the prepare target's printable polygon and margin, never a connected printer's axis-travel extents (about 271 x 335 on a U1). Every failing object is reported with its own fix, and objects_by_size carries each object's findings and fixes. Remembered measurements carry a content fingerprint and are stored only if the file is unchanged afterwards. The footprint read is bounded (see fix(placement): judge every build item, not every object id (#93) #102). Head b38a1a8; backend pytest 3228 passed, 49 skipped; desktop tsc, vitest (826) and build clean.

Review round 1 (Sol, Opus, Fable)

H4 unknown stays unknown (backend, report and desktop); H5 no 64-object cap; M6/M7 multi-plate and prime-tower wording are about size, not placement; wording follows Fable's text; scene-contract README and CHANGELOG updated.
Perf: each distinct object is collected once (keyed by part and object id) and its points moved per item; sizes and items count against the vertex limit separately; measurements and footprints are remembered per unchanged file; project_info only does this when placement_aware=True (insights, bed fit and the validation report).

Timings on a 37 MB synthetic 3MF (2 objects, about 290k vertices each; one process per call, cold)

call	before (#97 base)	after
`project_info`	0.42 s	0.41 s
`insights`	0.43 s	3.28 s
`bed_fit`	0.43 s	3.21 s
`report`	8.54 s	10.55 s
`predict_success`	17.64 s	16.78 s

The extra cost is the new capability (reading each mesh per object and per instance); it is paid only on the placement-aware paths and once per unchanged file. Callers that did not need it keep their old cost.

Verification

test_size_vs_placed_bounds.py (18), test_size_unknown_and_limits.py (14): translated, separated, multi-plate, inch, STL, unmeasured (renamed root model), 65 objects with the last too tall, first item scaled/rotated, measure-once and cache invalidation, vertex limit, two parts with the same object id; desktop sizeFit.test.ts.
Backend pytest: 3221 passed, 49 skipped. Desktop tsc, vitest (826 passed, including the prepare-copy guard) and build clean.

Not covered

layout.assess_layout keeps its existing placed-bounds logic. A per-object size ignores scale in the build item (a scaled instance shows up as a placement finding). No real Orca-authored multi-instance or multi-plate project was used. Cold cost on the placement-aware paths is still about 3 s for a 37 MB file. The size check still takes a connected printer's reported bed (axis travel) as its bed size, as before; and preflight (not changed here) still builds its own rectangle from it.

Summary by CodeRabbit

Bug Fixes
- Bed-fit results now assess each object’s size independently, so separate small objects aren’t incorrectly treated as one oversized object.
- Size and placement risks are reported separately, including when instances are outside the plate or exceed its height limit.
- Unmeasured objects are identified, and unknown sizes aren’t assumed to fit.
- Bed-fit checks use the identified printer’s printable area when connected, or the prepare-target profile when offline. If a connected printer can’t be identified, the result is unavailable.
- Multi-plate projects no longer use a combined extent for fit advice.

Size-only bed-fit statements read the overall mesh extents, so a small object moved off the plate still "fit", and separated objects or plates could add up to a combined extent that produced scale-or-split advice that was not about any single object. - geometry.object_sizes / measure: per-object size in mm (units-correct, before the build item moves, turns or scales it) from the same read as the placed per-item bounds. - plate_placement.placed_instances: per-instance placed bounds and plate; no combined extent across plates. - intelligence.project_info: object_sizes_mm and placed, with dimensions_mm kept and labelled as overall extents by size. - bed_fit: every size statement says "By size" and each object is judged on its own; placement is added separately ("By placement") and an off-plate instance makes the result a risk. - validation_report: "Fits the print bed" is per object, by size. - Desktop: Design Health bed-fit row is "by size" per object.

📝 Walkthrough

Bed-fit reporting now evaluates each measurable object’s size separately from its placement. Backend insights provide per-object sizes and placement data, and printer profiles define printable volume. Design Health and validation reports use per-object measurements.

Changes: Size and Placement Assessment

Layer / File(s)	Summary
Measure object size and placement data `backend/snapstudio_core/geometry.py`, `backend/snapstudio_core/placement.py`, `backend/snapstudio_core/plate_placement.py`, `backend/snapstudio_core/intelligence.py`	Geometry measurement returns per-object sizes, placed-item bounds, and unresolved items. Placement-aware project information exposes these results. Bounded caches store measurement and object-reading results.
Assess size, placement, and printer profile `backend/snapstudio_api/service.py`, `backend/snapstudio_core/bed_fit.py`, `backend/snapstudio_core/conditions.py`, `backend/snapstudio_core/validation_report.py`, `backend/snapstudio_core/intelligence_report.py`, `backend/tests/*`, `CHANGELOG.md`, `docs/testing/scene-contract/README.md`	Bed-fit assessment checks each measured object and placement separately. The service selects a printer profile and passes the assessment data to bed-fit reporting. Validation reports use individual object sizes. Tests cover printer profiles, unmeasured items, role handling, placement cases, and cache behavior. The changelog and scene-contract documentation describe the updated reporting.
Show per-object fit in Design Health `desktop/src/api.ts`, `desktop/src/lib/sizeFit.ts`, `desktop/src/lib/sizeFit.test.ts`, `desktop/src/components/DesignHealth.tsx`, `desktop/src/components/SizeNotChecked.test.tsx`, `desktop/src/routes/DesignInsights.tsx`, `desktop/src/routes/LiveWorkspace.tsx`	The Insights types and route wiring provide object sizes and unmeasured counts to Design Health. The size-fit helper checks objects individually and distinguishes oversized, unknown, and unmeasured results.

Full details: Linked Issues check

Explanation

Issue #91 requires intrinsic per-object sizes in millimetres, separate placed bounds per instance and plate, explicit consumer wording, and regression tests. The reviewed changes add per-object measurement, per-instance and per-plate placement data, separate “By size” and “By placement” results, and no combined-extents fallback when measurement is unavailable. The validation report and Design Health use per-object results. Tests cover translated, separated, multi-plate, unmeasured, and oversized-object cases.

Full details: Out of Scope Changes check

Explanation

The geometry measurement, placement analysis, role filtering, printer-profile selection, caching, consumer updates, conditions, documentation, and tests support the per-object size and placement objectives in Issue #91. The reviewed changes provide consistency and regression coverage for those objectives. No demonstrated change lacks a connection to the linked issue.

…ce (#91 repair) Merges the #93 repair (part-keyed items, unjudged instances, stricter move verifier) and then: - No fallback to the combined extents: with no per-object sizes the bed-fit, validation report and Design Health say "By size, Studio could not measure each object, so it cannot say whether they fit". Build items whose object is missing are counted (objects_unmeasured) and keep the result from reading as "everything fits". - bed_fit.assess_objects checks every object (no 64 cap). - Prime-tower and "share the plate" findings no longer turn a size into a placement claim; wording follows the review (By size, Snapmaker Orca). - geometry collects each distinct object once (keyed by part and object id) and moves those points per item; sizes and items count against the vertex limit separately; results and footprints are remembered per unchanged file. project_info only does this when placement_aware. - Design Health row: "Size only: where it sits on the plate is a separate check." - CHANGELOG and scene-contract README updated.

…91 repair 2) Merges the #93 repair (bounded footprint read, per-(part, object) instance numbers) and then: - The bed-fit placement check uses the prepare target's printable polygon and margin, never a connected printer's axis-travel extents (about 271 x 335 on a U1) anchored at 0,0. - assess_objects reports every object that fails, each fix naming its object, and objects_by_size carries each object's findings and fixes. - Remembered measurements are keyed by a content fingerprint as well as size and mtime, and are only stored if the file is unchanged after the measurement; a same-size, same-timestamp replacement is not served stale. - placed_instances numbers uses of the same (part, object).

…91 repair 4) Merges the #93 repair (content-keyed Ready Now cache, height from the printing parts) and then: - A connected printer Studio cannot identify reports axis travel, not a printable size: the bed-fit result is unavailable (size and placement both unknown), so 10 x 300 x 10 is no longer reported as fitting. - An identified printer is checked against its profile's recorded volume and labelled as the profile's, not as a live measurement. - The bed-fit placement findings check the placed Z (build-item scale included) with the same over_height rule preflight uses. - The geometry caches use fileid, the one content key. - The big-printer test derives its placement through the service.

…repair 5) Merges the #93 repair (below-plate parts, torn Ready Now reads, named printer) and then: - An object's size is the size of the parts that print, like its placed footprint: a 300 mm modifier next to a 10 mm cube no longer makes the object too large or too tall by size. - The bed-fit placement findings flag instances that reach below the build plane (a point to check, not a fit). - Stale docstrings and comments describe the printable-area behaviour; the big-printer test also drives service.bed_fit through printer identification.

Merges the #93 repair (roles propagate down through assemblies) and makes an object's size use the same rule through geometry: a non- printing role on an assembly applies to every descendant, roles on nested objects are consulted at every level, missing means a normal part, conflicting or unrecognised roles count. Tests go through service.bed_fit, the validation report and the per-object sizes for each of the four helper roles on a nested assembly (role on the assembly and on the nested record), a missing role, conflicting records and a child beneath a modifier. The big-printer test also asserts the preflight source names the printer from the derived placement.

Update the stale “What this does not do” paragraph.

The Units fix heading scopes the unit-scaling change, but the paragraph also describes current consumer behavior and defers the “By size” wording to PR 3c. The Known limitations section now records PR #104 as addressing this behavior. Update the paragraph to describe only the units-fix scope.

📝 Suggested fix

-What this does **not** do (decision, plan v4 item 1): the size-based consumers still answer "does the model's
-size fit the bed". They are not placement-aware. A small object translated off the plate, or separated instances
-whose union is large, is still judged by size only. The scene's placement findings are the placement-aware
-source. No consumer copy was edited here; qualifying those claims "by size" is PR 3c.
+What this does **not** do: the units fix changes only the unit scaling of each dimension source. It does not
+separate size from placement. That separation is described under "Known limitations" (issue #91, PR #104):
+size-based consumers judge each object's size ("By size") and report placement separately.

Use printable dimensions for the Design Health fit check.

caps.bed_mm describes printer axis travel, not the printable bed. Passing it to DesignHealth makes sizeRow compare objects with the wrong limits. An object that exceeds the printable profile but fits within axis travel can show “Fits” here while backend bed fit reports “Too big.” Pass printable dimensions from the identified profile, or withhold this row when the printable area is unknown.

Do not treat missing capabilities as an unreachable printer.

If diagnostics or history reaches a printer but the capabilities read fails, _printer_snapshot can have reachable=True and caps=None. This branch then falls back to the U1 profile and can report that objects fit a printer whose printable area is unknown. Use the snapshot’s reachability evidence to return an unavailable fit result when the reachable printer cannot be identified.

…unavailable bed fit is not verified Placement findings from bed_fit had no condition id, so the Intelligence Report treated them as unmapped and the legacy keyword fallback attached the out-of-bounds community fix and a generic next action. They now carry stable placement-* ids (no community entry) and their own action. A bed-fit result that could not be produced (unidentified printer, nothing measurable) is listed under not_verified instead of reading as no risk. Verified: backend pytest 3718 passed, 49 skipped, 0 failed on this tree; two new regression tests in test_intelligence_report.py. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>

Check the arrangement before recommending scaling.

_plate_fit compares each plate's combined cluster bounds with the printable area. Separate instances can therefore make fits false even when each instance fits individually. This reaches the oversized_plates message and can give incorrect scaling advice.

Add the not-judged action to fixes.

When placement is not judged and no other finding supplies a fix, these branches return a warning with an action but leave fixes empty. intelligence_report.build then reports a risk while saying Studio offered zero fixes. Add the same inspection step to fixes in both branches.

Qualify the no-risk headline when bed fit was not verified.

For the new test case with an unavailable bed fit and an otherwise OK mm result, this code adds "bed fit" to not_verified, but verdict still says “Studio's checks found no risks” and studio_line says the checks found nothing in the file. Make those headlines acknowledge the unchecked bed fit. Extend the test to cover the headline text.
