assignment based on part size. Update CuttingParametersSerializer for
round-trip serialization and add tests.

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.

Switch colorsList from CheckedListBox (which silently ignores owner

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.

- Replace Program.ToString() with Cincinnati-style formatter (spaced
coordinates, blank lines between contours, trailing zero suppression)
- Fix empty Program tab when switching files while on the tab by
loading immediately instead of only marking stale
- Set contour-type colors on entities at load time and restore base
colors before selection highlight to prevent color bleed to CAD view

Add a "Draw Cut Direction" toggle to the View menu that draws small
arrowheads along cutting paths to indicate the direction of travel.
Arrows are placed on both linear and arc moves, spaced ~60px apart,
and correctly follow CW/CCW arc tangents.
Extract all rendering methods (~660 lines) from PlateView into a new
PlateRenderer class, reducing PlateView from 1640 to 979 lines.
PlateView retains input handling, selection, zoom, and part management.

Restructure the cutting parameters dialog with separate Lead-In and

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

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.

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.

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
