OffsetOutward now normalizes to CW winding before offsetting instead of
trial-and-error with bounding box comparison. CadConverterForm designer
regenerated with new entityView1 properties.

- Route best-result updates to progress form preview in
PlateView.FillWithProgress (Ctrl+F path) — was still using
the old SetStationaryParts approach
- Only update results stats (parts, density, area) when
IsOverallBest so they match the preview display

FillGrid had no overlap check after perpendicular tiling of the row
pattern (Step 2), unlike Step 1 which had one. When geometry-aware
FindPatternCopyDistance underestimated row spacing, overlapping parts
were returned unchecked.
Changes:
- Make FillLinear.HasOverlappingParts shape-aware (bbox pre-filter +
Part.Intersects) instead of bbox-only, preventing false positives on
interlocking pairs while catching real overlaps
- Add missing overlap safety check after Step 2 perpendicular tiling
with bbox fallback
- Add diagnostic Debug.WriteLine logging when overlap fallback triggers,
including engine label, step, direction, work area, spacing, pattern
details, and overlapping part locations/rotations for reproduction
- Add FillLinear.Label property set at all callsites for log traceability
- Refactor LinearFillStrategy and ExtentsFillStrategy to use shared
FillHelpers.BestOverAngles helper for angle-sweep logic

Place circle labels on the circumference using golden angle distribution
so concentric circles don't overlap. Hide labels when the entity is too
small on screen to fit the badge.

Etch marks for up bends are now real geometry entities on an ETCH layer
instead of being drawn dynamically. They flow through the full pipeline:
entities → FilterPanel layers → ConvertGeometry (tagged as Scribe) →
post-processor sequencing before cut geometry.
Also includes ShapeProfile normalization (CW perimeter, CCW cutouts)
applied consistently across all import paths, and inward offset support
for cutout shapes in overlap/offset polygon calculations.

Wires the OpenNest.Data layer into the UI: adds project reference, creates MachineConfigForm (tree-based editor for machines/materials/thicknesses with import/export), and adds Tools > Machine Configuration... menu item.

- Parts tab: shows all BOM items, editable Material/Thickness for
matched rows, grayed-out rows for items without DXF files
- Groups tab: auto-computed from parts with editable Plate Width/Length
per material+thickness group
- Editing Material/Thickness on Parts tab immediately re-groups
- Per-group plate sizes preserved across re-groups

Fill must be at index 0 (front) so it's processed last by the

- Fix critical: use MdiParentForm (custom property) instead of MdiParent

- Add null guard in CreateNests_Click

- Improve summary label text with reason descriptions

Task 9: CreateNests_Click validates plate dimensions, then for each
MaterialGroup creates a Nest with name '{job} - {thickness} {material}',
sets PlateDefaults (size, thickness, material, quadrant=1, spacing),
imports each matched DXF via DxfImporter, converts entities to Program
with leading RapidMove offset handling (same pattern as CadConverterForm),
sets Quantity.Required from BOM qty, then opens an EditNestForm for each
nest that has drawings. Summary MessageBox reports count and import errors.

When a file is loaded, a background task analyzes the entities for

OptionsForm now shows checkboxes for each fill strategy, persisted via
the new DisabledStrategies user setting. FillStrategyRegistry exposes
AllStrategies and DisabledNames for the UI. MainForm applies disabled

Three bugs prevented the simplifier from working on ellipse geometry:
1. Sweep angle check blocked initial fit — the 5-degree minimum sweep
was inside TryFit(), killing candidates before the extension loop
could accumulate enough segments. Moved to TryFitArcAt() after
extension.
2. Layer reference equality split runs — entities from separate DXF
ellipses had different Layer object instances for the same layer "0",
splitting them into independent runs. Changed to compare Layer.Name.
3. Symmetrize replaced arcs with mirrored copies whose endpoints didn't
match the target's original geometry, creating ~0.014 gaps. Now only
applies mirrored arcs when endpoints are within tolerance of the
target's boundary points.
Also: default tolerance 0.02 -> 0.004, Export DXF button in
CadConverterForm for debugging simplified geometry.

Geometry Simplifier:
- Replace least-squares circle fitting with mirror axis algorithm
that constrains center to perpendicular bisector of chord, guaranteeing
zero-gap endpoint connectivity by construction
- Golden section search optimizes center position along the axis
- Increase default tolerance from 0.005 to 0.5 for practical CNC use
- Support existing arcs in simplification runs (sample arc points to
find larger replacement arcs spanning lines + arcs together)
- Add tolerance zone visualization (offset original geometry ±tolerance)
- Show original geometry overlay with orange dashed lines in preview
- Add "Original" checkbox to CadConverter for comparing old vs new
- Store OriginalEntities on FileListItem to prevent tolerance creep
when re-running simplifier with different settings
Bend Detection:
- Propagate bend notes to collinear bend lines split by cutouts
using infinite-line perpendicular distance check
- Add bend note text rendering in EntityView at bend line midpoints
DXF Import:
- Fix trimmed ellipse closing chord: only close when sweep ≈ 2π,
preventing phantom lines through slot cutouts

Use chars.Length instead of hardcoded 36 for modulus/division since

instead of '0' to avoid ambiguity.

DxfImporter now filters ETCH entities (like BEND) since etch marks are
generated from bends during export, not cut geometry. GeometryOptimizer
no longer merges lines/arcs across different layers and preserves layer
and color on merged entities. EntityView draws etch marks directly from
the Bends list so they remain visible without relying on imported ETCH
entities.

The remnant viewer previously always filtered by smallest part dimension,
hiding large remnants that were narrower than the smallest part. Added a

Add toggleable pierce point drawing to PlateView that shows small red
filled circles at each rapid move endpoint (where cutting begins). Wire
through View menu, EditNestForm toggle, and MainForm handler.
Also rename RectangleShape/RoundedRectangleShape Width/Height to
Length/Width for consistency with CNC conventions, update MCP tools and
tests accordingly. Fix SplitDrawingForm designer layout ordering and
EntityView bend line selection styling.

FitToPlate now places split lines at usable-width intervals so each
piece (except the last) fills the entire plate work area. Also adds a
live yellow preview line that follows the cursor during manual split
line placement, and piece dimension labels in the preview regions.

DrawingSplitter now clips bend lines to each piece's region using
Liang-Barsky line clipping and offsets them to the new origin. Bend
properties (direction, angle, radius, note text) are preserved through
the entire split pipeline instead of being lost during re-import.
CadConverterForm applies the same origin offset to bends before passing
them to the splitter, and creates FileListItems directly from split
results to avoid re-detection overwriting the bend metadata.

- Change split file suffix from _split# to -# (e.g., PartName-1.dxf)
