Change

A sheet.flange edge segment can now ask for a bend relief at the junction after it: relief: {shape, width?, depth?}. Before, two stretches that meet were never relieved, so a stretch that bends up beside one that bends down, or beside one that stays flatter, tore at the junction in the shop, or could not fold at all. The fix FR-13 asks for is a manufacturable blank, so the relief is cut out of the flat pattern and the DXF, not only drawn in the folded body.

shape is notch, straight, rectangular, obround or tear. notch is the default and is no relief, so a design that does not ask for one builds exactly as it did. width and depth are lengths and take the rule's relief_width and relief_depth (Thickness and Thickness x 0.5) when left out. round is refused: a round hole closes on itself and leaves material joining the two stretches out to the far edge, so the part still cannot fold (use obround with a depth of half its width).

The relief belongs to the segment whose to is the junction, so the last segment of an edge takes none, and a junction the merge closes takes none either. The build cuts the notch out of the parent panel (the base, or the flange's panel when the stretches sit on a flange's edge) and out of both stretches' panels: width across the junction, centred on it, from depth before the deeper of the two bend lines out to the nearer far edge. The two stretches are then parted there and joined only through the parent panel, depth back from the bend line, so each bend forms with a free end at the notch's side. Half of the width comes out of each stretch's own length, so it must fit the narrower one; nothing is clamped, because an unrelieved junction is the defect this feature exists to remove.

straight and rectangular cut the same footprint, a rectangle in the junction's frame. obround closes the notch's inner end with a half round of half its width (so its depth must be at least half its width, and the rule's defaults give exactly a half round on the inner bend line). tear cuts nothing in the flat plane and is the junction's own zero-width cut, started depth deeper into the parent panel, and it is cut whatever the two stretches' sides are.

The flat pattern and the DXF carry the notch on OUTLINE (an obround as one ARC), the junction's zero-width cut is dropped where a notch parts it, and both bends of that junction come out shorter by half the notch width in the bend table. No layer, entity or bend-table column is added.

A relief that would not leave a manufacturable blank refuses, naming the segment (edges[i].segments[j].relief ...): a depth past the parent panel into its bend zone; a tear whose deep end reaches an edge of the blank and parts it; a tear reaching a hole that touches that edge; a tear meeting an unrelieved junction from the other side; two tears from opposing edges whose slits overlap; a relief on the last segment of an edge; an obround whose depth is under half its width; a width that does not fit the narrower stretch; a round; a shape this build does not know; a width or depth that is not a length; a relief on a base or contour flange.

A design without relief loads and builds as before; the change is carried in one pending file, crates/doc/src/format/pending/junction-relief.rs, with its strings in assets/locales/pending/junction-relief.json.

The Flange dialog's segment rows gain a Relief choice (None, Notch, Straight, Rectangular, Obround, Tear) with Relief width and Relief depth. Split Edge moves a relief to the last part, and removing a row moves its relief to the row that takes its end, a row asking for none included, so no stale relief is left behind.

The solidcraft-sheetmetal skill and its reference now document the relief contract and when a junction needs one, and docs/book/src/guide/sheet-metal.md describes the shapes, the sizing rule and the cuts in the flat pattern and the DXF.

This design builds the three-stretch part from the segmentation PR with a notch at the first junction and a tear at the second:

{"commands":[

  "height":"20 mm","angle":"90 deg"}}
]}

This is the first Linux run of these tests: until now they have only run on this Windows box, so the GitHub run on this branch is the check that matters for the platform difference.

The full cargo xtask ci test phase exits 1 on this Windows box for failures outside this branch's diff (the repo's own tests/KNOWN_FAILING_TESTS entries and a handful of load-sensitive cases that pass when run alone on a clean checkout of origin/main). None of them is in cmd::sheet, the sheet doc module, dialogs_sheet, the i18n guard or the skill-reference test, and the targeted suites above are the ones this change touches.

Screenshots of the behavior (when observable)

None attached: the observable change is a notch in the flat pattern and a shortened bend in the bend table, which the tests assert line by line, plus a Relief combo in the Flange dialog. I can add a rendered flat pattern and a dialog capture on request rather than publish images that are not from this head.

Walkthrough

Segmented sheet flanges now support optional junction reliefs with configurable shapes and dimensions. The change adds relief validation, sheet geometry operations, dialog controls, tests, translations, and documentation.

Changes: Segment Junction Relief

Layer / File(s)	Summary
Relief contract and evaluation crates/doc/src/document.rs, crates/engine/src/cmd/sheet.rs, crates/doc/src/eval_more.rs, crates/doc/src/format/pending/*, docs/book/src/guide/sheet-metal.md, skills/solidcraft-sheetmetal/*	Segments now accept optional relief shape, width, and depth. Parsing and evaluation validate the values and pass relief requests to the sheet operation. The guides describe the supported shapes, defaults, and refusal cases.
Junction relief geometry crates/doc/src/sheet.rs, crates/doc/src/sheet_convert.rs, crates/engine/src/cmd/sheet_dxf_tests.rs, crates/engine/src/cmd/sheet_tests.rs	Sheet flange processing applies rectangular and obround cuts and updates junction slits for tear reliefs. The operation rejects invalid or blank-separating cuts. Tests cover geometry, DXF output, persistence, undo, and invalid requests.
Flange dialog support crates/ui-egui/src/dialogs_sheet.rs, crates/ui-egui/src/dialogs_sheet_tests.rs, assets/locales/pending/junction-relief.json	The dialog adds relief shape and dimension controls, serializes and restores relief data, and transfers or clears reliefs when segments change. Tests cover these state changes. Translations add relief labels in six locales.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: Moderate · previous review 3c581

Junction reliefs on segmented flanges can produce wrong or missing cuts in certain layouts. Examples are a parallel edge in the outline, a relieved stretch next to another flanged edge, and a mirrored sheet with a tear. The new locale file also lacks its required attribution entry, which fails the repository's asset check. Fix these before merging.

Security architecture risk: Low · up to 3c581

Relief requests now affect saved designs and manufacturing output. The inspected paths validate requests and isolate failed geometry changes from the accepted model. No introduced security failure was established, although compatibility and recovery coverage remain incomplete.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The inspected extension gives command or document input control over relief geometry in the evaluated sheet and its existing manufacturing output. It does not establish a new identity, credential, or execution-authority transition. Deployment-specific sharing or multitenant exposure was not established.

Trust Boundaries and Controls

• observed — The command parser rejects unknown relief keys and unsupported shapes. Document evaluation repeats shape and dimensional checks, so constructing a stored or programmatic flange feature does not avoid those evaluator controls. The geometry layer also refuses round junction reliefs.

Resilience and Maintainability Implications

• observed — Failure containment is provided at the feature-evaluation boundary, not by atomic rollback inside the geometry mutator. Evaluation clones state containing owned sheet and region values, and replaces accepted state only on success. A late relief refusal therefore discards partial working geometry; direct geometry callers must not assume the receiver remains unchanged after an error.

Full details: Title check

Explanation

The title names the main change: an edge-flange segment can request a bend relief at its junction, cut in the flat pattern and DXF. The changeset adds per-junction relief via sheet.flange segments with shapes, width and depth, flat-pattern and DXF cuts, and dialog support, so the title matches the primary change. It is long (122 characters), and it includes an issue reference, but it is specific and accurate.

Full details: Description check

Explanation

The description follows the template well. It opens with a plain-language Change section that explains the problem (stretches tearing or failing to fold at junctions) and the new behavior. It includes the required 'Changes a default: no' line, a Validation section with commands, results and expected values, and a Screenshots section that explains why none are attached. The Integration status section is missing. The description does not list the upstream commit and PR status before handoff, and it does not describe how the branch was kept in sync with upstream beyond noting the rebase. The Test change line is not needed because the change adds tests and does not alter kernel test expectations. The screenshot section explains the absence of images but does not show the behavior, and the template asks for evidence of visible behavior.

Resolution

Add an Integration status section that records the upstream commit and PR status checked before handoff, any conflicts resolved, and post-integration validation. Consider attaching a rendered flat pattern or dialog capture, as the template asks for screenshots of observable behavior.

Full details: Existing Defaults Unchanged

Explanation

The PR changes no existing UX default. The relief feature is additive, and the description's "Changes a default: no" is consistent with the code. Evidence from the reviewed range (refs/coderabbit/pre-merge-check/base..head, 14 files): - Engine command parsing (crates/engine/src/cmd/sheet.rs). The only removed lines are the segment-key error text and the FlangeSegment constructor. The new relief key is optional. A segment without relief builds as before. - Flat-pattern/DXF behavior. The PR text says notch is the default and "a design that does not ask for one builds exactly as it did." Any change to junction slits or piece-count refusals is a geometry or kernel result. The check excludes those from the UX-default criterion. - Flange dialog (crates/ui-egui/src/dialogs_sheet.rs). The one removed UI line is the standalone "Segment N turns" choice_row. It is replaced by a row that keeps the same turns dropdown, with the same labels and the same default way mapping. A new Relief dropdown, with width and depth inputs shown only when a shape is chosen, is placed beside it. The new control defaults to None, so the existing turns default and behavior do not change. The row layout is extended by an added control, not changed for existing controls. - Split and delete behavior. The relief transfer rules on Split Edge and row removal apply only to the new relief field. No prior behavior existed for them to change. - Other changes. Locale additions, docs, and skill text are additive or describe the new feature. Limit: this review used the diff and the description. It did not run the dialog. The layout change is additive, so it does not alter an existing default.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Leave the sheet unchanged when a relief is refused.

A deep tear can pass the dimension checks and fail this piece-count check. By then, add_flanges_relieved has trimmed the parent panel and appended the new flanges. A direct caller receives Err but retains the failed feature's geometry in its SheetBody. Apply the operation to a trial sheet and commit it only after all relief and final piece-count checks succeed.

Transfer junction relief ownership when mirroring a sheet.

flip_flat reverses each flange's bend-line ends, but leaves this new field on its original flange. After mirroring a two-segment edge with a same-side tear, the stored relief belongs to the later stretch. junction_slits checks the earlier stretch, so the mirrored flat pattern and DXF omit the requested tear. Move the relief to the mirrored junction's earlier stretch.

Pair junction stretches by their source edge, not by projection alone.

The partner test in cut_junction_relief matches any flange with the same parent, the same direction and the same projected u. It does not require the flange to come from the same outline edge. On an outline with two parallel edges that run the same way, a stretch can match a flange on the other edge. Example: outline (0,0),(3,0),(3,4),(2,1),(1,1),(1,3),(0,3), with the edge from (3,0) to (3,4) split at y = 1. The flange on the edge from (1,1) to (1,3) also starts at u = 1 and runs the same way. If it is added first, position returns it instead of the next stretch on the split edge. The relief then cuts or checks the wrong material.

junction_slits has the same gap. It compares only the projection along d, so it can pair stretches from different edges. When the bends are opposite, it can emit a slit across the strip between the two edges.

Record the source edge on each stretch, and use it in both the partner search and the junction_slits pairing. Two stretches on the same edge must match. Do not pair stretches on different edges, even when their projections match.

Keep a relieved outer stretch eligible for corner closing.

For a two-segment edge with a relief after its first segment, this loop calls set_panel_region on the second segment. That sets its shape to Some. If another edge is flanged in the same feature, corners excludes the second segment and leaves their outer corner unclosed. Select corners by the geometry at the outer end instead of excluding every shaped panel.

Use an independent expected notch position.

This test derives deep and far from the produced child.p, child.n, and child.leg. An incorrect child placement can move both the notch and the expected coordinates, so the outline assertion can still pass. Use coordinates fixed by the test fixture instead. As per path instructions, this layer “computes no geometry”; the new normalization and dot product also violate that rule.

Changes a default: preserve the standalone turn selector.

Before this change, each segment had a standalone turn choice. Now that choice occupies half of a row labelled “turns”; the adjacent relief choice has no visible “Relief” label. This layout applies even when the user has not chosen relief. No setting preserves the old layout, and the supplied PR description has no Changes a default: line. Keep the turn row unchanged and give the additive relief control its own label.

In the segment relief UI around `crate::ui_kit::dropdown`, hide or disable the selector for the last segment and ensure that segment cannot retain or serialize a relief value; keep the selector available for earlier segments.

Include relief in the segment field list.

Line 89 still says a segment is {from, to, angle?, height?, flip?} with “no other key.” The new contract permits relief. Update that list so an agent does not reject a valid command while following this reference.

Update the segment field list in the reference to include optional relief with the documented shape, width, and depth fields, and revise the “no other key” constraint so it permits this field while continuing to reject unspecified keys.

Limit bend shortening to material-removing reliefs.

This statement includes tear and notch. The same reference defines tear as zero-width and notch as no relief, so neither shortens a bend by half its configured width. Name the shapes that remove bend material.

Revise the junction-relief statement to limit half-width bend shortening to shapes that remove bend material; explicitly exclude tear and notch, which do not remove material, and preserve the stated behavior for angle, radius, and allowance.

Thanks for this, the relief shapes and the flat pattern/DXF cut look carefully thought through. Two things before I can take it:

1. It has a merge conflict with main now, so it needs a rebase.
2. It adds a Relief choice, Relief width and Relief depth to the existing Flange dialog, but the description has no pictures. Could you add screenshots at 1280x720, uncropped, showing the whole flow: the ribbon tab and button you press to open Flange, the dialog with a relief chosen, and the folded part and flat pattern that result? Please also include the dialog at a small window size (1280x720) so I can see the new rows don't overflow or jumble.

Holding this briefly: a sheet-metal refactor that replaces the flat-pattern model is landing first, and this will need to sit on top of it. I will ping you when it is in.

@lychee888 this PR is held for the sheet-metal refactor in #9245 (RFC #6748). To keep it from starting over when that lands, it has been ported onto the refactor as a draft: h0witzer#26. Your tests are its spec, and it credits you as the author. Have a look when you can; it retargets to main once #9245 merges.
