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.

Priority-based snapping: when the cursor is within 10px of an entity
endpoint or midpoint, snaps to it instead of the nearest contour point.
Diamond marker (endpoint) or triangle marker (midpoint) replaces the
lime dot to indicate active snap. Also refactors OnPaint into focused
helper methods and adds Arc.MidPoint().

Move Assign/Place/Remove Lead-ins from EditNestForm toolstrip to the

- 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

Wire up the Apply button to parse the G-code text back into a Program,
rebuild contours via ConvertProgram/ShapeBuilder/ContourInfo, and fire
ProgramChanged so callers receive the updated program.

Parts were not redrawn after AssignLeadIns because their LayoutPart

Remove LeadInsLocked guard so parts can be re-selected for lead-in
re-placement. Change preview color from yellow to magenta for better
visibility against the cyan contour highlight.

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.

Scribe/etch lines were being treated as cut contours by
ContourCuttingStrategy, receiving lead-ins and kerf compensation.
Now they are separated before ShapeProfile construction and emitted
as plain moves with LayerType.Scribe preserved.

The approach rapid from sheet origin was drawing to part.Location (the
program coordinate origin) then a second rapid to the actual first
pierce point. This created a dog-leg through the part origin instead
of a single straight rapid to the lead-in. Also fixed PlateProcessor
using the original program's start point instead of the processed one
when the cutting strategy is applied on-the-fly.

Save/restore cutting parameters as JSON in user settings so values

Scales down lead-ins that would place the pierce point too close to the
opposite wall of small holes. Uses quadratic solve to find the maximum
safe distance inside a clearance-reduced radius. Adds Scale() method to
all LeadIn types and applies clamping in both the strategy and the
interactive preview.

Three issues caused incorrect rendering after lead-in application:
- Rapid move entities from ToGeometry() were included in ShapeProfile
contour detection, turning traversal paths into cutting moves
- Program created with Mode.Incremental default made the absolute-to-
incremental conversion a no-op, leaving coordinates unconverted
- AddProgramSplit didn't call StartFigure() at rapid moves, causing
GraphicsPath to draw implicit connecting lines between contours
- Part.Rotation returned 0 from the new program instead of the actual
rotation, displacing the sequence label on rotated parts

Restructure the cutting parameters dialog with separate Lead-In and
Lead-Out GroupBoxes per tab, exposing editable length/angle/radius
fields for lead-outs (previously hardcoded). Add Tabs section with
enable checkbox and width control. Also fix lead-in/lead-out angle
calculations and convert cutting strategy output to incremental mode.

Adds a text-only toolbar button to the Plates tab that opens the
CuttingParametersForm, saves the chosen parameters on the plate, and
runs LeadInAssigner with LeftSideSequencer to auto-assign lead-ins.

Add GetGraphicsPaths/AddProgramSplit to GraphicsHelper that builds separate
GraphicsPath objects for cut vs lead-in/lead-out codes, skipping suppressed
codes. Update LayoutPart to use split paths when HasManualLeadIns is set,
drawing lead-in geometry in yellow regardless of selection state.

Break the 113-line click handler into single-responsibility methods:

- Route best-result updates to progress form preview in

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
