The cut simulation treated Display-layer contour moves (what cutting
strategies emit) as head-up travel, so plates with assigned lead-ins were
timed as rapids. They now cut, matching the verifier and posts, and
suppressed moves are left out.
Cut time now follows the CI Fiber post: closed clockwise contours and
cut-offs take an outside feed, other contours a hole feed, and etch-only
contours can be skipped like its SkipScribe default. The settings are
shared by Calculate Cut Time and the simulator, and plate/nest times now
always come from the simulation.

A Grbl-style lookahead planner re-times the cut simulation with
trapezoidal acceleration, junction-deviation corner speeds and a
centripetal cap on arcs. Machines gain cut/rapid acceleration and corner
deviation in Machine Configuration, with placeholder values until the
controller's are entered. The simulator and Calculate Cut Time pick the
machine (or full speed), and the simulator shows the live head speed.

Plate > Simulate Cutting replays the active plate in cutting order: the
torch traces cuts, rapids and pierces timed like Calculate Cut Time, with
play/pause, scrubbing, 1x-250x speed, step and part/cutout jumps. Parts
the torch has not reached are drawn muted.

Profiling the cutout pre-pass on real round-part jobs put ~97% of its time in
the frame-wall NestLayoutCheck.Clears inside CutoutCirclePacker.Fill. Ear-clipped
round frames make every perimeter/insert triangle pair overlap, so a clear pair
runs hole subtraction for every pair. The same question repeats for every frame
angle and repeated frame instance, because Automatic inserts get identical
frame-local poses.
- CutoutMemo, one per Prepare, replays geometry reads, circle items and Clears
answers. Keys hold geometry by reference, pose bit patterns, argument order
and spacing. It is threaded through CutoutCirclePacker.Fill and the router's
round-only path.
- TriangulatedRegion.SubtractAllHoles measures each piece's bounds once, skips
holes and hole triangles that no piece reaches, and ping-pongs the remainder
between scratch buffers instead of copying it into pooled ones. Clip
arithmetic and order are unchanged.
Bundles are byte-identical on 14 real and 10 synthetic ring jobs. Pre-pass time
over the real set drops from 99.6 s to 10.1 s (N0414-02 35.8 s -> 0.6 s).

- The cutout router uses the circle packer alone for a round hole whose
inserts are all round. Lattice and NFP never placed more there, and when
demand exceeded what fit they spent 20+ minutes on one job.
- The cutout pre-pass skips a hole whose area is smaller than an insert's
outline, so bolt holes no longer run the searches.
- Circles re-packs its last sheet, and its last two sheets together, onto
each single stock and keeps the result when the whole job gets cheaper.
On 14 real round-part jobs costs are unchanged and pipeline time drops from
262 s to 144 s for Circles and 355 s to 245 s for Default.

--autonest can now use more than one physical sheet. The first layout
replaces the target plate's parts, further layouts are inserted as new
plates after it, and --stock offers explicit sheet sizes (with optional
costs) built from the target's spacing, quadrant and clamp rail.
NestPipelineCommit gains ApplyToPlates for callers without a
PlateManager. Per-sheet results and overlap checks cover every
committed plate.

Dropping the parts that land on a clamp suits small parts, which fill the
gaps between clamps. Large parts often do better if the fill area stops
short of the clamps. The rows still fit, and no part is lost on a clamp.
When every clamp in the fill area lies on one edge, interactive Fill now
also fills the area with that edge moved just past the clamp keep-outs,
as a larger edge spacing would. It keeps whichever layout the strategy's
comparer ranks better, and a tie keeps the dropped-parts layout. Clamps
on more than one edge skip the comparison. The second fill reuses the
cached best-fit pairs. While it runs, a preview counts as the new best
only when it beats the first layout, so the preview never gets worse.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Interactive Fill on a plate with clamps used to split the plate into
clamp-free rectangles and fill each one separately. It showed no progress,
so Accept did nothing until the end, and Stop discarded the result. Packing
around the clamps also tends to give a worse layout than losing the few
parts that land on them.
FillItem and FillGroup now fill the area as if there were no clamps. They
then drop each part that enters a clamp keep-out or sits too close to an
existing part, using the same check as before. For a multi-part group, the
whole copy is dropped when any member fails. Progress previews are filtered
by the same check, so a layout accepted early is clamp-clear. A quantity
request that loses copies asks for that many more, up to two more times.
Pack and whole-plate Nest still pack only into the clamp-free areas.

Interactive Fill ran the best-fit pair phase first. The first pair
computation for a drawing can take about a minute, and until it finished
the progress dialog showed no layout, Accept stayed disabled and the
status text did not change.
The fill now packs the part boxes (RectBestFit) before the pair phase and
reports that layout, so Accept is available at once. The layout is only a
fallback: strategies still run in their usual order, and a completed fill
picks the same winner as before. While the pairs are computed, the detail
line reads "Computing best-fit pairs (may take a minute)...". Accept or
Stop now stops the wait. The computation keeps running in the background
and is cached for the next fill.

Circles packs every part as its minimum enclosing circle at centers tangent
to two of the work-area walls, placed discs and clamp keep-outs, bottom-left
and left-bottom, with hexagonal and square lattice seeds. It bids only when
every part fills at least 0.8 of its enclosing circle and otherwise returns
everything unplaced at once. Default runs it as a third candidate.
Rectangles' sheet-by-sheet stock loop moves to NestingEngines/SheetByStock
(Rectangles output unchanged) and Default's candidate scoring and commit
forwarding become shared helpers. Circles also runs the whole job preferring
each offered stock and keeps the best result. Contract tests take shapes an
engine can override.
Synthetic round jobs, salvage-credited: Circles wins or ties all six with
valid layouts; Default cost falls about 4% versus Irregular alone.

The cutout prepass now bundles frames smallest first, so a larger frame's
round cutout can take a ring part or an earlier bundle as one insert through
the circle packer: a flange holds a washer that holds a smaller washer that
holds a slug. Chains stop at four parts deep. Lattice and NFP proposals never
take these inserts, since they could seat a part in a ring's bore.
Expansion and released demand recurse, so placed order cuts innermost first
at every level and an unplaced outer frame returns its whole chain to demand.

Add CutoutCirclePacker, a circle-in-circle proposal for the cutout
router. When a cutout is one circle and every insert fills at least 0.8
of its enclosing circle, it packs the inserts largest first at centers
tangent to the wall or placed discs, trying a center-out pass (a single
insert sits concentric) and a wall-first pass (optimal counts for up to
nine equal discs). Every pose passes NestLayoutCheck.
The router runs it first and skips the lattice and NFP searches when it
places all demand; otherwise the higher count wins and existing
proposals keep ties. On synthetic disc jobs the prepass drops from
minutes to seconds and places as many or more inserts.

Item.Create builds the circle packer's view of a part: the minimum
enclosing circle of its outward-flattened perimeter (padded by the
layout check's flattening allowance), its fill ratio, the offset back
to the part origin, and the largest disc clear of material inside its
cutouts. Gears and sprockets pack by their tip circle around their
bore; the fill ratio lets a future engine decide which jobs to bid on
instead of a yes/no round test.
Adds MinimumEnclosingCircle (Welzl, repeatable order) to Core geometry.

Staggered stripes were spaced only so adjacent stripes touched
diagonally. When the in-stripe pitch stretched past sqrt(3)*D, stripes
two apart, which sit directly over each other, came closer than a
diameter. Clamp the stripe spacing to at least a radius in both fills.
FillEndOdd also divided by zero when a single circle fit per stripe;
it now stacks those stripes a diameter apart. FillEndEven now clones
the template item, so placed circles keep its radius instead of zero.

Select entities in the CAD converter (click, or drag a window/crossing
box) and right-click to exclude/include them or set them to cut, etch or
display only, regardless of their DXF layer. Delete excludes the
selection.
Roles are stored per source entity on the drawing and persisted in the
entity set as an optional `roles` map. Display-only geometry is kept out
of the program, so posts, nesting and verification never see it; placed
parts draw it as a dashed overlay. Load-time scribe repair skips
etch-layer entities set to cut. Per-entity exclusions now survive filter
changes.

Reads each stock as a bar and cuts parts in one row along its length, packing
part lengths with a port of the CutList saw cut-list packer (first-fit
decreasing with swap optimization, exhaustive search for small jobs) plus a
best-fill subset-sum candidate. Each part is packed at its length less its
measured self-nesting gain, and a slide-left compaction pass nests shaped ends
(turning alternate mitred parts) and refills the freed length. Every slid pose
is confirmed with NestLayoutCheck.Clears.
On five synthetic flat-bar jobs every layout is valid and complete; total cost
33696 vs Rectangles 36816 and Default 34080.

A tabbed cutout's slug stays attached while the sheet is cut, but nesting
saw a closed hole and could place parts inside it. Nesting and layout paths
now read material through NestingMaterial.ForNesting, which drops closed
contours with tab spans so the slug counts as part. That covers part
outlines and collision lines, the cutout router, fill expansion, best-fit,
NestLayoutCheck and the GPU bitmaps. Area, overlap diagnostics and cutting
keep the hole, and programs without tabs read exactly as before.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A hole can now be declared a tabbed cutout in the CAD Converter: pick a
circle or any edge of a closed hole, set the tab count and width, and drag
the tabs around the hole. The definition persists on the drawing and in the
nest file, and stays editable from the source entities.
The builder replaces the hole with open cut pieces and uncut spans on a new
Tab layer. Tabs are material, so area, nesting and overlap checks still see
a closed hole, but they are never cut. Plan Cutting and Assign Lead-ins cut
each piece from the slug with the internal lead-in and no lead-out. A lead
that would reach back over a tab is mirrored, and an arc lead onto an arc
pierces straight in. Planning accounts for each span between tabs and runs
the open-cut proof, so its own tabbed cutouts certify; tabs followed by a
lead-out are still refused. Pre-post review flags programs that still
contain tab motions.

A cutout cut in several pieces around tabs, as PEP programs often are, made
pre-post review report every piece's lead-out and the part's open fragments
as incomplete. Review now proves such open cuts release nothing: within the
part they touch other cuts only at their own ends and form no loop (each
closed contour with its leads counting as one point), and leads at open ends
stay out of the gap beyond them. Anything else stays incomplete. Plan Cutting
keeps refusing to certify its own tabs followed by a lead-out.

A cutout cut in pieces around tabs is a set of open cut figures. Filling the
cut outline closed each piece with a chord, drawing a slanted bridge across
the hole. The fill path now rejoins open figures across their tab gaps, and
parts with open cuts use it for drawing, hit-testing and the lead-in overlay.

Mouse-follow mode set the auto-sized location label on every MouseMove,

Rebuild the dialog as a two-column layout: a larger preview with a
color swatch, a Change Color button and read-only size, area and
source-file details on the left; Drawing (name, customer) and Nesting
(quantity, priority, cut first) groups on the right.
Quantity shows how many parts are already nested and how many remain,
priority explains that lower numbers nest first, and cut first gets a
short description. The form now uses Segoe UI with font auto-scaling,
re-renders the preview when its size changes, selects the name on
open, and is titled "Drawing Properties - <name>".

The v4 upgrade now keeps existing library data: each distinct package
blob is stored once by hash, every revision and current row is copied
with default nesting settings, and the v4 drawing tables are dropped,
all in the migration transaction. Pre-v4 databases get the v5 tables
directly.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Schema v5 stores each distinct drawing package once in drawing_packages,
keyed by SHA-256; revisions point at it, so details, settings, archive and
restore revisions add no blob. The v4 drawing tables are replaced outright
(no production library existed); nest tables are untouched.
Nesting settings (cut first, priority, rotation constraints, color) become
structured record fields (DrawingLibraryRecord.Settings), returned on every
read, filterable by cutFirst, editable through the metadata endpoint and
applied by LibraryDrawingInsert. Canonical packages now leave every
record-owned field at its default, so renaming or changing settings never
changes the package hash. Saving a nest drawing to the library carries its
settings into the record.
The desktop library browser gains a Cut first column and an Edit Settings
dialog that saves notes and settings as a new revision with the same package.

Drawings flagged CutFirst (e.g. test squares) are sequenced ahead of
every other part: they get their own route with the chosen method, then
the remaining parts follow. Cutoffs crossing a cut-first part still
precede it. The flag is editable in Edit Drawing, persists in .nest as
`cutFirst` (omitted when false) and is kept by split pieces.

Center Parts centred the parts on the whole plate, ignoring edge
spacing, so a wider clamp-side margin left the parts closer to the
clamps than the opposite edge. It now centres them in Plate.WorkArea()

the same extra room beyond its edge spacing.

Adds WithActive for handlers that only forward to the active nest
document and collapses 32 of them to one line. The eight align and
evenly-space items share Align_Click, reading their AlignType from Tag.
Center Parts becomes CenterParts_Click and ignores a missing plate or
an empty plate instead of throwing. The hidden, disabled Paste item
loses its empty handler. SetValueForm, OptionsForm and ShapeLibraryForm

MainStatusBar owns the status, location, selection and plate labels and

Moves startup and settings code out of MainForm:
- PostProcessorLoader discovers posts and registers their materials.
Each DLL now loads in isolation; a failing one is named in a startup
warning instead of throwing out of the MainForm constructor.
- MachineSettings owns the clamp-settings and nest-defaults entry points
and their once-per-session warnings; BomImportForm calls it directly.
- NewNestFactory creates File > New nests and their daily names;
GetNestName is now a pure static the characterization test calls.
- MainWindowSettings restores/saves window placement and migrates the
legacy nest template.
- UpdaterStatus owns the updater and its status-bar item.

Moves the long workflow handlers into OpenNest/Forms/Commands:
AutoNestCommand (dialog, owned modal progress, solve, validation review,
commit and result notices), PostCommand (prepare, configure, verify,
save dialog, multi-file overwrite confirmation) and NestStorageController
(database open/save/save-as with reconciliation and storage errors).
MainForm keeps the busy guards, the nesting lockout and nestingCts, and
reacts to the controller's StateChanged to lock storage settings and
saving. The characterization test now flips the controller's IsSaving
instead of the removed databaseSaveInProgress field.

Moves every MainForm busy predicate into MainForm.Guards.cs, built on
IsJobRunning, ViewsOf, IsPlateWorkBusy and IsNestFillBusy. Auto Nest,
Validate and Post share TryBeginPlateCommand; Clamps, Automatic Cutoffs

(Expand Spacing ignores busy actions; the report guard adds database
saves) keep their names and remain pinned by characterization tests.
NavigationEnableCheck now takes the lockout flag instead of
SetNestingLockout repeating its logic.

Breakoffs are now picked by their joining line, default to the smaller side as scrap
(flippable), and cut that line between tabs on a new Break layer instead of slots.
Plan Cutting and Assign Lead-ins enter each cut from the scrap with the nest's internal

cuts that are not material.

Forming backgauge tabs drawn as open cuts came off the sheet loose and could not be

NestPipelineResult.Unplaced lists each requirement's unplaced copies with a

at the sampled rotations, reserved in a cutout of an unplaced frame, stock
exhausted, plate limit, no position found, or proposal not keepable. Desktop
Auto Nest, Console --autonest and MCP autonest_plate/autonest_job report them;

NestPipeline.Run now bundles parts that fit other parts' enclosed cutouts
into their frames before the selected engine, for desktop, Console, MCP and
API alike. A valid complete bundled trial is kept; a refused trial falls back
to the ordinary solve (reason on RefusedCutoutTrial), and an incomplete trial
is compared with it, keeping whichever valid proposal places more. An
incomplete but valid trial is now keepable like any incomplete result.
Expanded sheets list each frame's inserts before the frame, so the committed
order cuts every insert before the cutout that releases its slug.

Posting review now proves containment exactly as the cutting planner does
(shared NestedPartContainment) and warns when a nested part is cut after its
host (NestedCutOrder) or when a host's hole lead or the nested part's lead

Ambiguous containment is incomplete, never clear; fixed-lead motions are not
reported twice. A committed cutout preview warns until Plan Cutting cuts the
insert first.
