PlateSizes holds standard mill sheet sizes (48x96 through 96x240) and
exposes Recommend() which snaps small layouts to an increment and
rounds larger layouts up to the nearest fitting sheet. Plate.SnapToStandardSize
applies the result while preserving long-axis orientation, and the
existing Ctrl+P "Resize to Fit" menu in EditNestForm now calls it
instead of the simple round-up AutoSize.

Replaces NominalPipeSize (double) with PipeSize (string), PipeClearance (double), and Blind (bool). GetDrawing cuts a center bore at pipeOD + PipeClearance unless Blind is true or PipeSize is unknown/null.

- Drop CadImportResult.Document: no caller reads it after the
migrations (BendDetectorRegistry runs inside CadImporter.Import
itself, and downstream callers only consume the entity/bend data).
- Drop dead CadConverterForm.GetNextColor() helper: zero callers
since GetDrawings stopped needing it.
- Drop stale 'using OpenNest.Properties;' and unused 'newItems'
local in OnSplitClicked.
- Add Import_WhenNamedDetectorDoesNotExist_ReturnsEmptyBends to
cover the previously untested named-detector branch in
CadImporter.Import.

The either/or format meant a SubProgramCall with both a non-zero
Offset and non-zero Rotation would only show the Offset, hiding the
rotation metadata. The data model supports both independently, so the
display should too.
Also fixes a zero-field leak where the old fallback emitted
`G65 P_ R0` for calls with no rotation. Now each field is only shown
when non-zero, and `G65 P_` with no arguments is emitted when
neither is set.
Note: SubProgramCall.ToString is purely a debug/display aid. The
Cincinnati post emits sub-calls via the G52 + M98 bracket, not via
G65, so this format doesn't correspond to real machine output.

ConvertMode.ToIncremental skips SubProgramCalls when computing deltas,
so all code paths that expand SubProgramCalls must: (1) set curpos to
savedPos + Offset before expanding, and (2) restore curpos afterward
so subsequent incremental codes get correct deltas.
Fixed in ConvertProgram, GraphicsHelper (AddProgram, AddProgramSplit),
PlateRenderer (DrawRapids, DrawProgramPiercePoints, GetFirstPiercePoint),
and CutDirectionArrows.

Inline sub-program geometry into the parent geometry list using Offset
as the starting curpos, replacing the Shape-wrapping approach.

Add Phase 3 curve-to-curve direct distance in CpuDistanceComputer to
catch contacts that vertex sampling misses between curved entities.
Enforce minimum copy distance in FillLinear to prevent bounding box
overlap when circumscribed polygon boundaries overshoot true arcs.

- Convert static class to instance with private constructor; shared
parameters (template, plateOptions, salvageRate, minRemnantSize,
progress, token) become fields, eliminating parameter threading
across all private methods (10→3 params on Nest entry point stays
unchanged; private methods drop from 7-9 params to 1-2)
- Extract FillAndPlace helper consolidating the repeated
clone→fill→add-to-plate→deduct-quantity pattern (was duplicated
in 4 call sites)
- Merge FindScrapZones/FindViableRemnants (98% duplicate) into single
FindRemnants(plate, minRemnantSize, scrapOnly) method
- Extract ScoreZone helper and collapse duplicate normal/rotated
orientation checks into single conditional
- Extract CreateNewPlateResult helper for repeated PlateResult
construction + PlateOption lookup pattern

The consolidation pass was iterating stale remnant lists after placing
parts, causing overlapping placements. Now recalculates remnants from
the plate after each fill operation. Also added plate options to the
real nest file integration test.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Small parts no longer create their own plates during the main pass.
Instead they're deferred to the consolidation pass which fills them
into remaining space on existing plates, packing multiple drawing
types together. Drops from 9 plates to 4 on the test nest file.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Small parts must only go into scrap zones (both dims < minRemnantSize)
to preserve viable remnants. The implementer had inverted this, giving
small parts access to all remnants. Also fixed the test to verify
remnant preservation behavior and removed unused FindAllRemnants helper.

Implements the main Nest() method that ties together sorting,
classification, and placement across multiple plates. The method
processes items largest-first, placing medium/small parts into
remnant zones on existing plates before creating new ones. Includes
private helpers: TryPlaceOnExistingPlates, PlaceOnNewPlates,
TryUpgradeOrNewPlate, FindAllRemnants, and CloneItem.

Adds IsScrapRemnant(), FindScrapZones(), and FindViableRemnants() to
MultiPlateNester. A remnant is scrap only when both dimensions fall
below the minimum remnant size threshold (AND logic, not OR).

Introduces PartClass enum and Classify() static method that categorizes
parts as Large (exceeds half work area in either dimension), Medium
(area > 1/9 work area), or Small.

Implements static MultiPlateNester.SortItems with BoundingBoxArea and Size sort orders, covered by two passing xUnit tests.

Circle.ToPoints() always generated CCW points regardless of the Rotation
property, so reversing a circle contour in the CAD converter had no effect.
Now negates the step angle when Rotation is CW, matching Arc.ToPoints behavior.

Consolidated two stateless classes into one unified API: Dxf.Import(),
Dxf.GetGeometry(), Dxf.ExportPlate(), Dxf.ExportProgram(). Export
state moved into a private ExportContext. Removed bool+out pattern
from GetGeometry in favor of returning empty list on failure.

Spline import now uses SplineConverter (arc-based) so the configurable
precision parameter is obsolete. Removed the setting from the options
dialog, DxfImporter property, Settings files, and all callsites.
Hardcoded 200 as the sampling density for the intermediate point
evaluation that feeds into SplineConverter.

Without this, RemoveEmptyPlates would destroy the sentinel with no
recovery, and tail-plate subscriptions would go stale after plate list
mutations. Added tests for both scenarios.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
OnPlateAdded now navigates to the new plate when suppressNavigation is
false, matching the original EditNestForm behavior. Fixed CanRemoveCurrent
test to account for this auto-navigation.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- EnsureSentinel() maintains exactly one trailing empty plate, suppressing navigation events during mutation
- Reactive tail subscriptions (PartAdded/PartRemoved on last two plates) call EnsureSentinel automatically; re-subscribed after each plate list change
- BeginBatch()/EndBatch() defers sentinel enforcement during bulk operations
- GetOrCreateEmpty() returns or creates an empty plate; RemoveCurrent() removes the current plate with index clamping; CanRemoveCurrent guards deletion
- 13 new tests (30 total PlateManager tests), all passing
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Introduces PlateChangedEventArgs and PlateManager in OpenNest.Core to centralize plate navigation logic (CurrentIndex, LoadFirst/Last/Next/Previous/At, IsFirst/IsLast). Includes full xUnit test coverage (17 tests) verifying navigation, event firing, and disposal unsubscription.

Always keep a trailing empty plate so users can immediately place parts
without manually adding a plate. Auto-appends a new sentinel when parts
land on the last plate; trims excess trailing empties on removal.
Plate list now shows Parts count and Utilization % columns. Empty plates
are filtered from save and export. Sentinel updates are deferred via
BeginInvoke to avoid collection-modified exceptions and debounced to
prevent per-part overhead on bulk operations.

Tries each candidate plate size via the nesting engine, compares results
by part count then net cost (accounting for salvage credit on remnant
material), and returns the best option.

BuildOffsets had Width and Length swapped after the Box axis correction
in c5943e2. Horizontal pushes used Length (X) for perpendicular sweep
and Width (Y) for push start — backwards. This caused part2 to start
inside part1's footprint, producing overlapping best-fit pairs.
Added regression test that verifies no kept best-fit pairs overlap.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Box constructor and derived properties (Right, Top, Center, Translate, Offset)
had Width and Length swapped — Length is X axis, Width is Y axis. Corrected
across Core geometry, plate bounding box, rectangle packing, fill algorithms,
tests, and UI renderers.
Added FillSpiral with center remnant detection and recursive FillBest on
the gap between the 4 spiral quadrants. RectFill.FillBest now compares
spiral+center vs full best-fit fairly. BestCombination returns a
CombinationResult record instead of out params.

Adds ApplySingle to ContourCuttingStrategy that applies lead-in/out to
only the contour containing the clicked entity, emitting other contours
as raw geometry. Also adds ApplySingleLeadIn wrapper to Part.

Add AutoTabMinSize and AutoTabMaxSize properties to enable automatic tab
assignment based on part size. Update CuttingParametersSerializer for
round-trip serialization and add tests.

Instead of emitting separate M98 calls per identical sheet, use the L
(loop count) parameter so the operator can adjust quantity at the control.
M50 pallet exchange moves inside the sheet subprogram so each L iteration
gets its own exchange cycle. GOTO targets now correspond to layout groups.
Also fixes sheet name comment outputting dimensions in wrong order.

Rapid traversing back to origin over a sheet of freshly cut parts risks
collisions with tipped or warped pieces. Removed from both the sheet
footer and part subprogram endings.

Cutoff features now substitute plate-edge coordinates with #SheetWidthVariable
and #SheetLengthVariable references. Vertical cutoffs at Y=plate_width emit
Y#110, horizontal cutoffs at X=plate_length emit X#111. Segmented cutoffs
only substitute the edge coordinate, interior segment endpoints stay literal.

When programs have user-defined variables, the Cincinnati post now:
- Assigns numbered machine variables (#200, #201, etc.) to non-inline variables
- Emits declarations like #200=48.0 (SHEET WIDTH) in the variable declaration subprogram
- Emits X#200 instead of X48.0 in coordinates that have VariableRefs
- Handles global variables (shared number across drawings) vs local (per-drawing number)
- Inline variables emit the literal value as before
