Move the expensive per-part hit-test out of OnMouseMove and into
the hoverTimer callback. The hit-test now only runs once after
1000ms of stillness, not on every mouse move event.

Add a hoverTimer that restarts on each mouse move over a part.
Tooltip only renders after the timer fires, hiding while the
cursor is in motion.

Path.IsVisible was consuming 52% of CPU on mouse move. Add a cheap
GetBounds().Contains() check first so only parts under the cursor

Remove dead programIdFont field, unused imports (OpenNest.CNC,
System.ComponentModel, OpenNest.Math, System.Collections.ObjectModel).

Moves preview part lifecycle (stationaryParts, activeParts) into a dedicated
PreviewManager class. PlateView retains forwarding properties and methods for

Move cut-off drag interaction mechanics into a dedicated CutOffHandler
class, reducing PlateView complexity and following the same pattern
established by SelectionManager extraction in Task 1.

Move all selection state and operations (SelectedParts, SelectedCutOffs, DeselectAll, SelectAll, AlignSelected, RotateSelectedParts, PushSelected, GetPartAt*, GetPartsFromWindow, DeleteSelected) into a new internal SelectionManager class. PlateView retains public forwarding methods and properties to preserve the existing API surface. SelectedCutOff property kept public for WinForms designer compatibility.

The WM_ERASEBKGND suppression from 3c4d00b left stale artifacts
in the non-item region when the control was resized. Fill only
the area below the last visible item so items still don't flicker.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Add entity-based DirectionalDistance overload to SpatialQuery that
uses RayArcDistance/RayCircleDistance instead of tessellating arcs
and circles into line segments
- Add GetOffsetPartEntities, GetPerimeterEntities, GetPartEntities to
PartGeometry for non-tessellated entity extraction
- Update Compactor.Push to use native entities instead of tessellated
lines — 952 circles = 952 entities vs ~47,600 line segments
- Use bounding box containment check to skip cutout entities when no
obstacle is inside the moving part (perimeter-only for common case)
- Obstacles always use perimeter-only entities since cutout edges are
inside the solid and cannot block external parts

The filter only checked ShortestSide against the plate's short dimension,
allowing results where the long side far exceeded the plate length.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
ListBox is a native Win32 control so ControlStyles.OptimizedDoubleBuffer
had no effect. The erase-then-redraw cycle on each Invalidate() caused
visible flashing. Suppressing WM_ERASEBKGND is safe because OnDrawItem
already fills the complete item bounds.

UpdateRemovePlateButton() was only called from PlateListChanged,
not CurrentPlateChanged, so the button stayed disabled after switching

Three fixes to TryUpgradeOrNewPlate and a new post-pass:
1. Change ShouldUpgrade from < to <= so upgrade wins when costs are
tied (e.g., all zero) — previously 0 < 0 was always false
2. Guard against "upgrades" that shrink a dimension — when options are
sorted by cost and costs are equal, the next option may have a
smaller length despite higher width (e.g., 72x96 after 60x144)
3. Revert plate size when upgrade fill fails — the plate was being
resized before confirming parts fit, leaving it at the wrong size
4. Add TryConsolidateTailPlates post-pass: after all nesting, find the
lowest-utilization new plate and try to absorb its parts into
another plate via upgrade. Eliminates wasteful tail plates (e.g.,
a 48x96 plate at 21% util for 2 parts that fit in upgraded space).
Real nest file: 6 plates → 5 plates, all 43 parts placed.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- 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>
After the main single-pass placement, leftover items are now packed
together using the engine's multi-item Nest()/PackArea() methods
instead of creating one plate per drawing. First tries packing into
remaining space on existing plates, then creates shared plates for
anything still remaining.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Previously, parts classified as "Large" skipped all existing plates
and always created new ones. This caused one-unique-part-per-plate
behavior since most parts exceed half the plate dimension. Now large
parts search viable remnants on existing plates before creating new
ones, matching the intended part-first behavior.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Wires part-first mode from AutoNestForm into RunAutoNestAsync: reads
PartFirstMode, SortOrder, MinRemnantSize, and AllowPlateCreation from
the form, passes them through to a new part-first branch that delegates
to MultiPlateNester.Nest instead of the plate-first loop.
Co-Authored-By: Claude Sonnet 4.6 <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.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Adds IsScrapRemnant(), FindScrapZones(), and FindViableRemnants() to
MultiPlateNester. A remnant is scrap only when both dimensions fall

When an item was too large for every plate option, its dimensions dominated
the global min-dimension filter, causing all candidate plates to be rejected.
This made auto-nesting exit immediately with no results even when the other
items could fit. Oversized items are now excluded from the filter so the
remaining items nest normally.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- Try all valid best fit pairs instead of only the first when qty=2,
picking the best via IsBetterFill comparer (fixes suboptimal plate
selection during auto-nesting)
- Pre-compute best fits across all plate sizes once via
BestFitCache.ComputeForSizes instead of per-size GPU evaluation
- Early exit plate optimizer when all items fit (salvage < 100%)
- Trim slide offset sweep range to 50% overlap to reduce candidates
- Use actual geometry (ray-arc/ray-circle intersection) instead of
tessellated polygons for slide distance computation — eliminates
the massive line count from circle/arc tessellation
- Add RayArcDistance and RayCircleDistance to SpatialQuery
- Add PartGeometry.GetOffsetPerimeterEntities for non-tessellated
perimeter extraction
- Disable GPU slide computer (slower than CPU currently)
- Remove dead SelectBestFitPair virtual method and overrides
Reduces best fit computation from 7+ minutes to ~4 seconds for a
73x25" part with 30+ holes on a 48x96 plate.

Without this, RemoveEmptyPlates would destroy the sentinel with no

Replace direct plate collection event handlers, navigation methods, and
sentinel logic in EditNestForm with PlateManager delegation. Navigation
buttons, list selection, export, and plate removal now route through
PlateManager. Backward-compatible delegating wrappers kept for MainForm
until Task 7.
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

- Strategies now promote results to IsOverallBest when they beat the
pipeline best, so the UI updates immediately on improvement rather
than waiting for each phase to complete
- PlateView only updates the main view on overall-best results, fixing
intermediate angle-sweep layouts leaking to the plate display
- Skip Row/Column strategies for rectangle parts (redundant with Linear)
- Intercept Escape key at MainForm level via ProcessCmdKey so it always
reaches the active PlateView regardless of focus state
- Restore keyboard focus to PlateView after fill progress form closes
- Remnant engines use SelectBestFitPair for orientation-aware pair
selection; DefaultNestEngine tries both landscape and portrait pairs
- RemnantFiller preserves more parts during topmost-part removal

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.

Strategies and fillers previously called NestEngineBase.ReportProgress
directly, each constructing ProgressReport structs with phase, plate
number, and work area manually. Some strategies (RectBestFit) reported
nothing at all. This made progress updates inconsistent and flakey.
Add FillContext.ReportProgress(parts, description) as the single
standard method for intermediate progress. RunPipeline sets ActivePhase
before each strategy, and the context handles common fields. Lower-level
fillers (PairFiller, FillExtents, StripeFiller) now accept an
Action<List<Part>, string> callback instead of raw IProgress, removing
their coupling to NestEngineBase and ProgressReport.

ActionLeadIn.DisconnectEvents() nulled selectedLayoutPart without first

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>
ObservableList.Remove fired ItemRemoved even when the item wasn't in
the list, causing Plate to decrement Quantity.Nested for clone preview
parts that were never added — producing -1 counts. Delete in PlateView

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

ComputeNormal assumed CW winding for all contours. For CCW-wound cutouts,
line normals pointed to the material side instead of scrap, placing lead-ins

Instead of emitting separate M98 calls per identical sheet, use the L

Cutoff features now substitute plate-edge coordinates with #SheetWidthVariable

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
