Near-zero-sweep arcs with large radius (e.g. from ellipse converter) have
nearly-coincident start/end points. Downstream code (ConvertProgram, Program
BoundingBox) treats coincident start/end as a full 360° circle, inflating the
bounding box and rendering wrong geometry. Emit a LinearMove when sweep is
negligible — geometrically equivalent and avoids the ambiguity. Also fix the
ellipse converter to produce lines instead of degenerate arcs at the source.

Arcs with sweep angles smaller than Tolerance.Epsilon were treated as
full circles by IsBetweenRad's shortcut check, causing UpdateBounds to
expand the bounding box to Center ± Radius. This made zoom-to-fit zoom
out far beyond the actual part extents.
Skip cardinal angle expansion when sweep is near-zero so the bounding
box uses only the arc's start/end points.

Tabs were being applied to internal cutouts and circle holes, which is
incorrect — only the external perimeter should be tabbed. Restructured

instead of the confusing implicit override behavior.

ArcToLineClosestDistance used geometric closest-point as a proxy for
directional push distance, which are fundamentally different queries.
The heuristic could overestimate the safe push distance when an arc
faces an inclined line, causing the Compactor to over-push parts into
overlapping positions.
Replace with analytical computation: for each arc/line pair, solve
dt/dθ = 0 to find the two critical angles where the directional
distance is stationary, evaluate both (if within the arc's angular
span), and fire a ray to verify the hit is within the line segment.

Feature list becomes grouped tables (Import/Export, Nesting, Plate
Operations, CNC Output). Nest file format section expands to cover the
newer entities/programs/subs layout. Drawing Splitting section gains a
paragraph explaining cutout-aware clipping: Liang-Barsky line clipping,
arc-vs-region intersection, and connected-component detection that emits
one drawing per physically-disconnected strip.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Splits that cross an interior cutout previously merged physically
disconnected strips into one drawing and drew cut lines through the hole.
The region boundary now spans full feature-edge extents (trimmed against
cutout polygons) and line entities are Liang-Barsky clipped, so multi-split
edges work. Arcs are properly clipped at region boundaries via iterative
split-at-intersection so circles that straddle a split contribute to both
sides. AssemblePieces groups a region's entities into connected closed
loops and nests holes by bbox-pre-check + vertex-in-polygon containment,
so one region can emit multiple drawings when a cutout fully spans it.

The either/or format meant a SubProgramCall with both a non-zero
Offset and non-zero Rotation would only show the Offset, hiding the
rotation metadata. The data model supports both independently, so the
display should too.
Also fixes a zero-field leak where the old fallback emitted
`G65 P_ R0` for calls with no rotation. Now each field is only shown
when non-zero, and `G65 P_` with no arguments is emitted when
neither is set.
Note: SubProgramCall.ToString is purely a debug/display aid. The
Cincinnati post emits sub-calls via the G52 + M98 bracket, not via
G65, so this format doesn't correspond to real machine output.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
CincinnatiSheetWriter.WriteHoleSubprogramCall emitted
`M98 P<num> X<x> Y<y>`, but per manual §3.98 ("M98 SUB-PROGRAM CALL
WITH NO ARGUMENTS") M98 takes only P and L — the X/Y had no defined
meaning to the control. The intent was to position the sub-program at
the hole center, which is what G52 is for per §1.52 ("local work
coordinate system") and which explicitly does not move the nozzle.
Emit the documented G52 bracket instead:
G52 X<hole.x> Y<hole.y>
M98 P<holeSubNum>
G52 X0 Y0
The hole sub-program is authored in hole-local coordinates, so its
first rapid (the lead-in to the pierce point) resolves to the absolute
pierce under the G52 shift and moves the tool directly there from the
previous feature's end — no phantom rapid to the hole center.
Also add docs/cincinnati-post-output.md as the reference for the full
post output format, with every emitted G/M code cross-referenced to
the Cincinnati programming manual. Un-ignore docs/ (docs/superpowers/
stays ignored) and track the PDF manual alongside the reference.

The SubProgramCall branch in DrawRapids used to draw a rapid from the
previous feature's end to the hole center, then rely on the sub-program's
own first rapid to draw from center to the lead-in pierce. That rendered
a phantom center-hop segment that doesn't exist physically — a
SubProgramCall is a coordinate-frame shift (emitted as a G52 bracket on
Cincinnati), not a move to the hole center.
Look ahead through the sub-program for its first pierce point in
absolute coordinates and draw a single direct rapid from pos to that
pierce. Recurse into the sub with skipFirstRapid: true so the sub's
first rapid isn't drawn again on top.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
ConvertMode.ToIncremental skipped SubProgramCall codes entirely when
computing deltas, so parent motions after a sub-call were encoded as if
the tool never moved. Several traversal sites (ConvertProgram,
GraphicsHelper, PlateRenderer, CutDirectionArrows, Program.BoundingBox)
worked around this with save/restore hacks that treated sub-calls as
transparent — but DrawRapids legitimately tracks actual tool position,
so after the last hole the first perimeter rapid was applied to the
wrong base, drifting the rendered perimeter past the plate edge by
roughly the distance to the last hole.
Fix the root cause: ToIncremental and ToAbsolute now walk sub-programs
to compute where they leave the tool, and advance pos accordingly. The
other traversals capture a frameOrigin at entry and compute sub-call
placement as frameOrigin + Offset, letting pos advance naturally
through the sub recursion. All the save/restore workarounds are
removed.
Program.BoundingBox also picks up the same frame-origin treatment,
which corrects a latent bug where absolute-mode endpoints and nested
sub-calls dropped the parent's frame origin.

ConvertMode.ToIncremental skips SubProgramCalls when computing deltas,
so all code paths that expand SubProgramCalls must: (1) set curpos to

PlateRenderer (DrawRapids, DrawProgramPiercePoints, GetFirstPiercePoint),

SubProgramCalls are now treated as standalone features in the Cincinnati
post-processor. SplitByRapids emits them as single-element features
instead of splitting on rapids within sub-programs. A nest-level hole

PairEvaluator was cloning the full CNC program (including all internal
cutouts) for every candidate. For parts with many holes (e.g. 952),
this caused O(n²) overlap checks and thousands of unnecessary polygon

from it, and uses that for all Part.CreateAtOrigin calls. Cutouts are
irrelevant for best fit — only the outer boundary matters for pairing.

External lead-ins now sit on the line between the last internal cutout

sequencing starts from the bounding box corner opposite the origin and

LoadItem was resetting all entity visibility to true, overriding the

Entities now have a Guid Id for stable identity across edit sessions.
Drawing stores the full source entity set (SourceEntities) and a set of
suppressed entity IDs (SuppressedEntityIds), replacing the previous
SuppressedProgram approach. Unchecked entities in the converter are
suppressed rather than permanently removed, so they can be re-enabled
when editing drawings again.
Entities are serialized as JSON in the nest file (entities/entities-N)

Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
The vertex-to-entity approach in DirectionalDistance only sampled 4
cardinal points per circle, missing the true closest contact when
circles are offset diagonally from the push direction. This caused
the distance to be overestimated, pushing circles too far and
creating overlap that worsened with distance from center.

treating the problem as a ray from one center to an expanded circle
(radius = r1 + r2) at the other center. Includes arc angular range
validation for arc-to-arc and arc-to-circle cases.
