- 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.

Adds a right-click "Delete" option on the drawings tab that removes the
selected drawing and all its placed parts from every plate.

Rebuild the dialog from a flat layout into grouped sections: engine
selector at top, Parts group with rotation columns and summary label,
Options group, collapsible Plate Optimizer with single-field size
parsing, and a clean button bar. Adds engine sync between dialog and
toolbar.

Add LoadPlateOptions() method to AutoNestForm that restores saved plate
options and salvage rate from the Nest. Call this method in
RunAutoNest_Click when opening the dialog if saved options exist, and save
settings back to Nest after dialog completion.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add PlateOptions and SalvageRate properties to the Nest class and
round-trip them through NestWriter/NestReader via a new PlateOptionDto.

When "Optimize plate size" is enabled in AutoNestForm, NestSinglePlateAsync
calls PlateOptimizer.Optimize instead of engine.Nest, trying multiple plate
sizes and resizing the plate to the winning option.

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.

Add colored left-edge bars (green=met, orange=short) to indicate nesting
quantity status. Replace blue selection highlight with a border outline.
Add toolbar toggle to hide fully nested drawings, auto-updating as parts
are placed or removed.

Enables a "move" workflow: clone parts to a new position, then
press Delete to remove the originals. Previously Delete just
cancelled the clone action.

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
setting IsSelected = false, leaving the part permanently rendered in the
selection color (transparent blue) after switching actions.

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.

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
now cancels ActionClone instead of trying to remove its preview parts.
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.

- Add general-purpose ShowSidePanel/HideSidePanel to EditNestForm
- CuttingPanel uses Dock.Top layout so collapsible panels reflow
- Add loop selection step: click contour to lock before placing lead-in
- Stay on selected part after placing a lead-in
- Delete unused LeadInToolWindow

Remove CuttingParametersForm modal dialog. PlaceLeadIn_Click,
AssignLeadIns_Click, and AssignLeadInsAllPlates now initialize
cutting parameters from saved settings or defaults instead of
showing a dialog. The CuttingPanel tool window (in LeadInToolWindow)
replaces the form for interactive parameter editing.

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.

Shape.Area() returns Math.Abs(signedArea), so DetermineWinding always
detected CCW regardless of actual winding. Use ToPolygon().RotationDirection()
which uses the signed area correctly.

ComputeNormal assumed CW winding for all contours. For CCW-wound cutouts,
line normals pointed to the material side instead of scrap, placing lead-ins
on the wrong side. Now accepts a winding parameter: lines flip the normal
for CCW winding, and arcs flip when arc direction differs from contour
winding (concave feature detection).

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

Emit variable definitions before G-code in program text entries and use
\$varName syntax for coordinate fields that have VariableRefs, so programs
round-trip through NestWriter → NestReader without losing variable information.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
ProgramReader now supports G-code user variables with a two-pass
approach: first pass collects variable definitions (name = expression
[inline] [global]) and evaluates them via topological sort and
ExpressionEvaluator; second pass parses G-code lines with $name
substitution and VariableRef tracking on motion and feedrate objects.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Adds Dictionary<string,string> VariableRefs to Motion (cleared on Rotate/Offset) and string VariableRef to Feedrate, with deep-copy Clone() support, so post processors can emit variable references instead of literal coordinate values.

Also set ContinueOnError=true on Cincinnati's post-build copy to prevent

Adds immutable VariableDefinition record to OpenNest.CNC with name,
expression, resolved value, inline, and global flags. Fixes namespace

Switch gcodeEditor from TextBox to RichTextBox and colorize G-code
tokens: rapids (amber), linear cuts (green), arcs (blue), comments
(dim gray), and mode codes (purple).

Remove the Apply button and OnApplyClicked handler since the gcode
editor is now read-only. Add contour label comments (e.g. "; Hole 1
(CCW)") to the formatted gcode output so users can see which feature
each group of codes belongs to.

Only include cut-layer entities when building the ShapeProfile for lead-in
placement, instead of removing just scribe entities. This prevents display,
lead-in, and lead-out geometry from interfering with contour detection.

Material and thickness are properties of the nest (all plates share the
same material/gauge), not individual plates. This moves them to the Nest
class, removes them from Plate and PlateSettings, and updates the UI so
EditNestInfoForm has a material field while EditPlateForm no longer shows
thickness. The nest file format gains top-level thickness/material fields
with backward-compatible reading from PlateDefaults for old files.

Move 43 root-level test files into feature-specific subdirectories

Switch colorsList from CheckedListBox (which silently ignores owner
draw) to a plain ListBox with manual checkbox, color swatch, and hex
label rendering. Clone entities in ProgramEditorControl preview to
avoid mutating originals. Remove contour color application from
CadConverterForm. Fix struct null comparison warning in SplitDrawingForm.

Resolve lead-in points by walking backward through cutting order (from
perimeter outward) so each lead-in faces the next cutout to be cut
rather than pointing back at the previous lead-out. Extract EmitContour

The CAD converter and BOM import were stripping the leading RapidMove
after normalizing program coordinates to origin. This left programs
starting with a LinearMove, causing the post-processor to use that
endpoint as the pierce point — making the first contour edge zero-length
and losing the closing segment (e.g. the bottom line on curved parts).
Root cause: CadConverterForm.GetDrawings(), OnSplitClicked(), and
BomImportForm all called pgm.Codes.RemoveAt(0) after offsetting the
rapid to origin. The rapid at (0,0) is a harmless no-op that marks the
contour start point for downstream processing.
Also adds EnsureLeadingRapid() safety net in the Cincinnati post for
existing nest files that already have the rapid stripped.

Convert programs to absolute mode before extracting features for
