The part cut first no longer makes a separate uncompensated centerline
cut with its own lead-in and lead-out, then re-pierces for its
remainder. It cuts its outside compensated, which puts its shared edge
on the kerf centerline, starting on the common line: a straight lead-in
from the scrap along the shared edge, then the line and on round its
perimeter with no lead-out. A member with spans already cut stops in
that kerf and cuts its last stretch from it, ending beside the part it
is cut before. Partners still cut only their remainders.
Replay's tabbed-ring accounting now accepts pieces that tile each span
exactly once, and the pre-post review counts a span as cut by a
member's compensated edge (or an older centerline cut).

Straight spans of one pair that meet at a corner chain into one shared
path (CommonLineGeometry.Paths). Plan Cutting cuts it as one open
centerline cut through its corners, pierced and left in scrap along its
end legs; each member's spans run on to its own vertex at a corner, so
the path is one tab run. Join Common Line slides along the main edge so
the step of a Z or L also lands one kerf apart, and the plate draws the
path through its corners.

Extension lines now walk in from the dimension line until they come 6px from
the drawing's outline, as on the CAD Converter, passing measured points that
are off the outline (a rounded rectangle's sharp corners). The flange bolt
circle is a leader landing on the dotted circle from outside, between holes,
instead of a linear dimension whose extension lines crossed the flange.

The Shape Library's hole diameter leader now crosses its hole through the
center to the far edge, arrows pointing out onto both edges, wherever the
label is dragged. The hole pattern dimension measures a dotted bolt circle
through the hole centers.

The first fill of a new drawing was blamed on the best-fit pair search, but on the
reported nest that search takes ~3.4 s. The time goes to FillLinear.FillGrid, run
thousands of times by the Pairs, Row/Column and Linear strategies: pattern copy-distance
slides and the grid overlap check. Every change keeps the output bit for bit (part
poses compared on the benchmark nest; best-fit results unchanged).
- ConvexDecomposition.Triangulate: unlink clipped vertices from a circular list instead
of List.RemoveAt, and remember why a vertex failed the ear test (same neighbors, same
blocking vertex still present) instead of retesting it after every ear. Compared
bitwise against a frozen pre-change copy, including the blocker-clipped case.
- Collision: skip triangles whose box misses the other triangulation's union box (exact:
min/max and monotone subtraction), reuse each triangle's open vertices, and let the
overlap-only path stop at its first region when there are no holes. Check still
returns every region.
- SpatialQuery.ExtractEntityVertices presizes its set; FillLinear extracts each entity
list's vertices once per copy-distance search rather than once per pair.
- StripeFiller converges its stripe angles and tiles its grids in parallel. Dedup claims,
cached remnant fills, ranking and progress stay in candidate order, and grids are tiled
only for configurations a claim can still win (GridDedup.Contains), so results and
reports do not depend on the thread count.
- LinearFillStrategy fills its angles in parallel through
FillHelpers.BestOverAnglesInParallel; angle results, ranking and progress stay in order.
Benchmark (one drawing, 60x120, 0.25 spacing, cleared plate, interleaved runs):
FillItem Lattice 291/317 s -> 164/153 s, 132 parts both; PairFiller alone 48 s -> 38-42 s.

The Shape Library no longer has a side panel of inputs. Each length is a
dimension line or leader on the preview; click its label to type a new
value (Enter applies, Esc cancels, Tab moves to the next dimension), as
Edit Clamps does on the plate. Invalid values keep the editor open in
red and the last good shape on screen. Settings with no place on the
drawing (sides, pipe size, clearance, blind) are clickable notes along
the bottom. The flange hole leader carries the count beside the size,
such as "Ø7/8" x 8 holes".
Shapes declare their dimensions through ShapeDefinition.GetDimensions;
lengths show as fractions when exact to 1/64 (Fraction.Format). Edit
Clamps' inline text box moves to a shared DimensionBox.

The pair filler topped its grid off with single parts at 0 or 90 degrees,
so a narrow strip beside the grid held half of what it could: on a 60x120
sheet of N26-29X parts the plate fill gave 132, while deleting the last
column and filling the strip gave 136. The strip is now also laid out the
way the Row strategy lays one, rows of best-fit pairs turned so whole pairs
span it, and that layout replaces the singles when it places more.
Each strip size is laid out once per fill and skipped when the singles
already fill it by area. On the benchmark nest the plate fill now reaches
136 with the hand-made layout's rotations, about 17% slower (156 s vs
133 s with best fits cached). The pinned L-shape fills gain a part (52 to
53). The auto-nest problem-nest corpus keeps its baseline.

Copying a layout meant recreating the plate and copying its parts by hand.
Ctrl+drag a row in the Plates list drops a copy at that slot; the row's
right-click menu has Duplicate Plate, which inserts the copy after it.
Plate.CopyLayout copies the sheet (size, outline, spacing, quadrant, grain,
clamps, support bed), the parts with their programs and lead-in state,
common-line groups and cut-off definitions, regenerated in their places in
the sequence, as a save and reload would. The copy is one sheet with no
stock item codes, since those name particular physical sheets. The desktop
gives it its own cutting parameters and records it as one undo step.

The empty new-plate header read only "New plate (empty)", so the sheet
size of the plate about to be nested was hidden until parts were added.

The corpus is meant to hold every nest that ever caused a problem, tagged with
what it guards, but it could only plan cutting paths. Nests tagged
`checks: auto-nest` now run the Default engine on their demand and fail when the
layout is invalid, leaves parts unplaced, or uses more sheets than their
`auto-nest: N sheets` line; planner runs skip them.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The Layout label counted parts off the plate or inside the edge spacing, but
nothing showed which part or where, so the user had to hunt for it. Each edge
finding now gets a canvas marker like the overlap and spacing ones: a red
crosshair where a part leaves the sheet and an orange ring at the gap to the
edge, in every visible display mode, with hover text that carries the finding's
message. Markers are retained across edits like the other overlay findings
(only a changed part's marker drops), and a sheet size, edge spacing or outline
change clears them. Validate Nest already located these findings through
PostVerificationFinding.Location.
"Near edge" / "inside the edge spacing" read as a spacing rule rather than a
placement problem, so the label, overlay messages, PlateEdgeReview findings
and the Validate Nest category now say the part is outside the work area. Off
the plate keeps its wording. The PostVerificationKind.EdgeSpacing name stays.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The status bar's "Layout: OK" ran its own snapshot check of overlaps and
part spacing, separate from Validate Nest and posting, so a part dragged
off the sheet still read OK.
The plate capture now owns the sheet frame (sheet box, work area,
outline), and the worker runs PlateEdgeReview's material check on it:
"N off plate" and "N near edge" join the label. Snapshots hold no leads,
so leads past the sheet stay a Validate Nest/posting finding. The
geometry stamp now includes edge spacing and outline so changing them
marks the result out of date. Bare-part captures (Plan Cutting) have no
frame and are unchanged.

Six-decimal incremental PEP programs round arc centers, so an arc's end
tangent misses its neighbor's by about gap / radius (1.6e-5 rad on the
offset 5/32" fillet in the reported nest). Two parts resting one spacing
apart then gave the slide contact a Minkowski cone a hair wider than a
half-plane, which the classifier read as the whole plane: every direction
blocked, so the top part could not be pushed sideways along the part below.
SlideContact now reads a cone up to TangentSlack (1e-4 rad) past a
half-plane as a noisy half-plane and widens its boundary and concave-ray
comparisons by the excess, so near-tangential slides read as tangential.
A direction admitted that way can enter material by at most travel x
excess at that contact, and every other contact is still classified on its
own; wider cones remain real overlap and block. Raising JointTolerance was
not needed for this case and is left at 1e-6.
Whole-job benchmarks (synthetic nests plus the PEP job at 3 and 60 parts,
--parallel 1) are identical before and after for every engine.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A part placed exactly one part spacing from its neighbor touches the
neighbor's offset contour. PEP drawings round arc centers to six decimals,
so their offset contours carry hairline kinks and joint gaps where the parts
touch; the slide kernel then classifies that contact as blocking in every
direction, and Push moved the part 0 even straight away from the neighbor.
An obstacle whose bounds end at or behind the moving part's trailing side
can only fall further behind, so Push and PushBoundingBox now skip it
(within Tolerance.Epsilon) instead of only when strictly behind.

Slice 3 of common-line cutting. On costly plate (N26-295: 3/16 RA310S at about
$2,500 a sheet) pairing parts one kerf apart fits the part the spacing cannot:
the last plate's 38 parts fit on one 48x120 with Auto Nest only with pairs.
- Drawing Properties gains "Allow common line" (Drawing.AllowCommonLine, off by
default because customer edge-quality needs vary). The nest's CommonLineUsage
(Off / When it adds parts / Whenever available) is set in Auto Nest and seeded
from Tools > Nest Defaults; both persist (nest.json, defaults.json).
- NestPipeline runs the ordinary solve, then, with a level on, trials where
eligible parts are offered as kerf-gap pair compounds. Placed pairs expand into
parts plus explicit NestJobCommonLine groups, are validated again, and
CommonLineRanking keeps a trial only by the level: count first, then sheets;
"when it adds parts" keeps the plain layout on a tie, "whenever" also takes a
shorter cut or less material, never at the cost of a part. Engines, FillScore
and their comparers are unchanged; Off asks the engine exactly what it did.
- NestLayoutCheck exempts members only through a sheet's explicit group list and
only when the job allows common lines; materializing and committing create
Plate.CommonLines.
- Server nesting writes common-line jobs as version 3 and replays the recorded
trial answers, so the desktop binds the same groups.
- Fill Area honors the level through a PlateFillService overload.
- The benchmark gains --common-lines <level> --kerf <k>.
Benchmark (synthetic nests + N26-295, --parallel 1): with no flag and with
--common-lines off every engine matches the base commit; with a level on no
layout becomes invalid and three runs save a sheet at equal nested area.

N26-295's PT42 pairs saved spacing in slice 1 but every shared edge was
still cut twice, costing a pass per edge and risking a freed part
tipping under the head on the second pass.
Plan Cutting now cuts a plate's common lines once unless the plate is set
to cut them twice. Each group is cut member by member, owner before
partner (a captured dependency that search and replay enforce, so a kept
order cutting the partner first is a constraint conflict): the member's
holes, then the shared cuts it owns as open CommonLine centerline cuts
entered through the notch on the span's axis, then its remainder pieces,
each ramped in from the kerf the shared cut opened. Capture marks the
shared spans as tabs on the owned clean copy, so replay's contour
accounting proves each perimeter is cut exactly once; a lead that fits
at neither end refuses as UnsupportedGeometry naming the span, never
shortened. Material still comes from the drawing, so utilization,
quantity and overlap results do not change. Members are never
support-tabbed; locked or excluded members and broken groups refuse.
The CI Fiber post writes shared cuts in the cut-off form with a lead-in
and no G41/G42, and remainders in the contour form on their perimeter's
compensation side, named by a remainder comment. Cincinnati CL (whose
PreApplied mode offsets nothing) and Gravograph refuse such nests, as do
the desktop and console for any post without ICommonLinePostProcessor;
nothing falls back to a silent double cut. Plate > Arrange > Cut Common
Lines Twice keeps slice 1's behavior, persists with the plate and makes
an open plan stale.
Pre-post review now checks each span is cut once, on its centerline, by
the member cut first, and the rapid check treats a finished member's
remainders as an obstacle. Compensation start in void and cancel in
kerf are unconfirmed on the CI FIBER 4020; release waits on a 3/16
stainless coupon trial.

Expensive alloy jobs (N26-295, 310 stainless) could not fit their last
PT42 at full part spacing; the plate was squeezed to 0.2 spacing with a
part 0.14 from the edge. Parts whose straight edges face each other one
kerf apart are cut on the same centerline, saving the spacing along each
shared edge.
Plate.CommonLines holds groups of parts and the kerf they were joined
at. Shared spans are derived from the placed clean perimeters, never
stored, so a moved member breaks its group instead of leaving a stale
span. Plate > Arrange > Join Common Line slides the selected parts
together at the plate's kerf; Remove Common Line ungroups them. The
plate draws shared spans as a dashed centerline.
Both spacing checks hold group members to the kerf instead of the part
spacing, and a new pre-post Common lines check reports broken groups, a
changed kerf, and leads that run into a partner. Groups persist as part
positions in an optional commonLines array that older readers ignore.
This first slice still cuts every shared edge twice; single-pass cutting
through Plan Cutting and the posts comes next.

Ring-shaped parts (a plate with a large center hole) were left unlabeled:
the material at their pole is too narrow for the ID, and the label was
never tried anywhere else. Group IDs were likewise only ever placed beside
the dotted outline, so a cramped cluster lost its ID or straddled the
sheet edge.
A part whose pole spot is too tight now takes the roomiest clear spot
within its own extents, such as its empty hole. A group ID takes the
roomiest spot inside its outline or beside it; with none clear it may
cover the group's own parts near the center, since operators read part
detail from the parts list. No ID sits across the sheet outline.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Each dotted group outline was padded 1 pt beyond its parts. At overview scale
a 0.25 in part spacing is only ~1.3 pt, so the outlines of two adjacent
clusters (e.g. the six small bars and the two holed plates on N26-27Y plate 1)
overlapped, and the later group - with its ID - was silently dropped.
Pad outlines by under half the part spacing instead, so neighboring clusters
both get their outline and ID.

The Database-mode Open dialog now allows multi-row selection and a Get
Materials command (button and context menu) that downloads the chosen
nests, or every nest the current search matches across all pages, and
lists the sheets they use by material, grade, thickness and size with
the quantity and the nests using each. Needed to order stock for a whole
job's worth of nests at once instead of opening them one by one.
Material, grade and thickness come from each nest's server record;
sizes and duplicates from its plates, skipping plates with no parts.

Validate Nest and the pre-post review checked overlaps and part-to-part
spacing but never the sheet itself, so a part dragged past the plate edge,
a lead-in piercing off the sheet, or a part inside the edge spacing could
post without a warning. Only Auto Nest's own layout check held parts to
the work area.
PlateEdgeReview adds two finding kinds:
- OffPlate: any cut, lead or scribe motion past the sheet, or clean
material outside an outlined sheet or over one of its obstacles.
- EdgeSpacing: clean material (leads excluded) outside the work area, or
closer than the largest edge spacing to an outline or obstacle - the
bound Auto Nest's layout check applies, with SpacingSlack, so layouts it
accepted stay clear.
Cut-off parts are exempt. Routing-replay test fixtures sit at the sheet
origin with leads hanging off it; their route assertions now ignore the
sheet-bound kinds, and the post-contract fixture moves onto the sheet.

Tabs suit thin plate, but on anything thicker than 0.25 in the parts
are too hard to break out of the sheet, and the Cutting Parameters
dialog was one global set for every job. Its settings now live on the
nest's machine thickness: leads on the existing Outside/Inside Cuts
tabs, and lead-in angle rounding, tabs and pierce on a new Tabs &
Pierce tab (ThicknessConfig.Cutting). In Database mode every
workstation gets the same settings through the shared machine.
The dialog and the Place Lead-in panel say what they edit, and save
back to that thickness (MachineCuttingDefaults.WriteTo, converted to
the machine's units). A thickness with no Tabs & Pierce of its own, or
a nest the machine has no thickness for, keeps this PC's settings as
before. If the machine can't be saved (server offline, a conflict),
the edit is kept on this PC for that job and the user is told.
Machine Configuration can copy one thickness's Tabs & Pierce to
thinner or thicker ones, so the 0.25 in rule takes a few clicks.
An older desktop saving a shared machine would silently erase these
settings, since it doesn't know them. Machine configuration classes
now keep unknown fields, and the server refuses a machine save that
leaves out a field the stored machine has a value for, telling the
user to update OpenNest.
The Plan Cutting status line now reports tabs from SupportTabs; since
"Tab every part" was retired it always said off.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Nobody tabs every part, but tabbing by size is useful even on a plate
that has a support grid. Cutting Settings > Tabs now offers "Only tab
parts the support grid can't hold level" or "Tab parts by size"
(CuttingParameters.TabBySize), which ignores the bed and tabs each part
whose minimum-area bounding rectangle's narrow side is in the range.
The support grid choice still falls back to that range on plates with
no bed, as before.
The range fields become TabSizeMinWidth/TabSizeMaxWidth; their JSON
keys stay noBedTabMinWidth/noBedTabMaxWidth so saved settings and nests
read unchanged. TabsEnabled stays as the per-contour flag Plan Cutting,
Place Lead-in and drawing pins set on the parts they tab.
Saved user settings with "Tab every part" read as tabs by size from 0
to 9999, which tabs the same parts. Only the user's settings migrate;
a plate's recorded parameters and pins replay as planned.
Plan Cutting, Place Lead-in and the pre-post review all go through
SupportTabSettings, so they agree on which parts need a tab. A
size-tabbed part is held by any clear tab, so it is never a rapid
obstacle.

A tail separator that landed on a front-edge clamp was skipped outright, so
a plate lost its whole remnant (19.5 in on a 48 x 120 sheet with the part
ending at a rail clamp) over a 1.5-in clamp. The separator now steps to the
clamp's far edge plus its clearance, repeating for any clamp it then meets,
and reports ClampMovedTailSeparator. The kept tail is shorter by that
distance and must still meet the minimum tail length; a separator pushed off
the sheet still reports NoSafeTailSeparator.

The Circle fill strategy's stripe layouts (FillEndOdd, FillEndEven) now try
switching from staggered to straight stripes, a diameter apart over the last
staggered stripe, at every stripe, all staggered and all straight included,
and keep the switch that places the most; a tie stays staggered. A 9" circle
on a 60x120 sheet at 0.2 spacing now fills 89 (five staggered rows, two
straight) instead of 88.

Resize to Fit snapped layouts larger than 48x48 to a hardcoded list of
inch mill sheets, so a plate already on a full sheet could not shrink to
its parts, and the cutoff ignored nest units and the machine's stock
sizes. It now rounds the parts' extent up to the auto-size plate factor
at every size through Plate.AutoSize.
Removes Plate.SnapToStandardSize and PlateSizes.Recommend with its
options; the sheet list and label lookup stay for Machine Config.

Nest reports showed "-" for every part weight on N26-295 because the nest and
its drawings store Stainless Steel 310 with density 0: materials are picked by
name and grade, and nothing copies a density onto them. The densities live in
the machine material defaults, and for this nest not even on its own machine
(CL-980 lists only 304; 310 is on CI FIBER 4020).
The desktop now resolves a catalog density before capturing the report: the
nest machine's exact name and grade, any machine's exact name and grade, then
the same material name. A density stored on the nest still wins, and the
drawing's own material stays the last fallback.

Operators want plates of the same size grouped together so material
doesn't need sorting when it arrives; there was no way to change plate
order. Rows can now be dragged to a new position (with a drop line and
edge auto-scroll), or moved with Alt+Up/Alt+Down. Each move is one
undoable "Move Plate" step and only reorders: quantities are untouched.
The trailing empty new-plate sentinel stays last. An empty plate moved
to the end becomes the sentinel, as the sentinel rule already does on
reload, so the order shown is the order saved.

The summary's parts table squeezed each thumbnail into a 62 pt column and
had no room for the size and weight the shop asks for. Each drawing is now
a card, four to a row: ID, a larger thumbnail, name, bounding-box size,
weight each and for all nested copies, required/nested counts and plates.
A shortage or extra is a badge beside the ID (SHORT in red) so it stays
easy to spot without a column to scan.
Weight is net area x nest thickness x material density, read as lb/in^3
like the machine material defaults; millimeter jobs report kilograms. A
nest without thickness or density shows "-" and a note saying what is
missing, never a zero weight.

Group outlines and their shared ID were rejected whenever they touched
another part's bounding box. A large irregular part's box can cover most

(e.g. test squares) were left with no ID at all. Test clearance against
real contours instead, as individual labels already do.

The nest report joined contour segments only within 1e-12, but converted
arcs rebuild their end from the start radius and end angle. Rounded or
incremental programs (end radius a few 1e-7 off the start radius, which
the report's own validator accepts up to Tolerance.Epsilon) left every
arc a hair short of the next move, so outlines split into open pieces
and N26-27K's parts printed unshaded as if they had tab gaps.
Join within Tolerance.Epsilon instead, still far below ShapeBuilder's
welding tolerance and real tab gaps.

Delta review fixes:
- ReleaseRenest throws when a commit does not call finish, or calls it
twice: either would leave ledger plates uncoded or count a sheet twice
for later nests of the run. The ledger sheet count is the codes given.
- A stage whose layout is not kept now lists the copies its layout
missed with their own reasons (a part no sheet fits stays "does not
fit"); only the copies it placed are "the proposal cannot be kept".
- A valid ledger layout that places nothing says "Auto Nest placed
nothing on it" rather than claiming no part fits.
- ReleaseLedgerOffer rejects null rows; docs list every ledger note.
Review fixes for ledger-first Make Nests:
- The release renest (offer, staged run, codes, note) moves into
OpenNest.Desktop.ReleaseRenest, shared by the headless panel, the
live main window and the tests. Codes are given inside each commit, so
the live tab's Auto Nest undo step records them; before, undo and redo
dropped every ledger code.
- A bundle repeats one code per sheet: a later nest of the run lost the
whole bundle once an earlier nest took one sheet. Taken sheets are now
counted per code (LedgerCodeFilter.ExcludeCopies).
- A stage whose layout is not kept lists every copy it asked for as not
placed (the proposal cannot be kept), and a rejected ledger layout
says "MaterialLedger not used: Auto Nest could not keep a layout on
its stock" instead of a bare "No MaterialLedger stock used".
- "no free stock" is said only when the ledger had none; otherwise the
note counts what was left out (on other nests, taken by earlier nests
of this release, too small, unknown shape).
- The ledger is not read for a nest with nothing to nest, the live read
runs under the tab's stop token, a reason's own full stop is not
doubled, and the sheet count is the codes given.
NestRenest gains a staged run: a nest is nested on finite first stock
alone, then whatever is left on its plate defaults and plate-size
options. Each stage keeps only a valid layout, and the result lists the
stock id each committed plate was solved on.
ReleaseLedgerStock is the ledger stock of one Make Nests run: each nest
is offered the free sheets and drops Auto Nest's ledger load would tick
for its material, grade and thickness (substitutes included), minus
codes on other open server nests (read once per run) and codes earlier
nests of the same run took, which are not on the server until the
release uploads them. Committed ledger plates get their codes as Auto
Nest gives them. An unusable ledger nests on the plate defaults and the
note says why the ledger was not used.
A cutout's lead-out ends in its slug, so the rapid after it always crossed
the cutout just cut and the strict search refused every plan with cutout
lead-outs. The slug is free and may drop or tip, so emission now marks that
rapid to raise the head, and the rapid check accepts a raised rapid that
starts at the lead-out's end and leaves its cutout exactly once. Cutouts
without a lead-out, or with an overcut, still leave from the cut head down.

The last strip line stops at the remnant's full-length horizontal
separator, so it never counted as separating the sheet and the planner
cut it wherever the route passed it, often first (N26-264). That frees
the X-tail remnant early and loses the mass that absorbs heat while the
parts are cut.
A continuous line from a sheet edge or separator to another now counts
as a separator too (CutOff.Separators, found in rounds), so Plan Cutting
and Part Sequencing cut it after every part, just before the separator
it stops on. The problem-nest harness now adds scrap cut-offs with
KeepHorizontalRemnant, as both desktop entry points do.

Priority worked like a rank (lower first) with a default of 0, and the
Edit Drawing form stopped at 0, so moving one part ahead of the rest
meant renumbering every other drawing. Higher-first lets a user raise a
single part to 1 and leave everything else at the default.
Every engine, filler and candidate comparer now serves the highest tier
first. Stored values keep their order:
- .nest files add `nestPriority` and keep writing the negated value under
`priority`, so older readers nest in the same order; files without
`nestPriority` are negated on read. Drawing packages strip both, so
package hashes are unchanged.
- Library settings send both keys the same way for older clients.
- Server schema v18 negates stored drawing priorities (an older server
refuses the upgraded database).
- Job documents move to version 2; version 1 jobs are converted, and an
older worker refuses version 2 instead of reversing the order.
The Edit Drawing form now accepts negative priorities and says higher
numbers nest first.

A part with lead-ins applied could not be pushed away once another part
touched it. PartGeometry kept LEADIN/LEADOUT entities as material, so the
leads chained onto the perimeter as open spurs and the spacing offset no
longer closed. The slide-contact classifier cannot tell the material side
of an unclosed boundary and blocks every contact, so parts resting against
it could not move up or right off it. Leads are cut into scrap, and the
spacing review, overlap analyzer and support checks already drop them.

A tab entered at a fillet joint trims back around the corner, so the cut
stops on one edge and starts on the other. Each straight lead took its own
edge's normal and the pair sat 150 degrees apart, reading as one bent line
through the corner. Both now take the bisector of the two ends' normals and
form the same V they form on a straight edge, falling back to their own
normals when either lead would not clear the part.

A support-tabbed part that no single tab can hold level may tip once cut,
yet its tabbed outside was crossable like any retained part, so Plan
Cutting could rapid back across a row of long strips. Its outside is now a
rapid obstacle, closed across its tab gap, in the search, replay, cut-off
insertion and the safest route.
Its fallback entries are ranked toward the next cut rather than steadiest
first, so a long strip can be left toward the next part, and the "cut those
two the other way round" rule applies only when the approach crosses no
other part.

After its six variants and tail re-plan, Irregular decodes the job again
with each type of three or more copies packed as one group, in a searched
order, holding back up to four copies per group that would start a ragged
row and filling them into the gaps afterward. When everything fits, the
best candidates are re-packed in a strip ending just short of the front.
The pass runs after the ungrouped search, which is unchanged, and replaces
its result only by beating it. The help tutorial's parts now end at 34.9"
instead of 38.1" on 60 x 120.

With the CL post declaring placed order for nests it writes as planned,
the help tutorial's nest must reach posting with no findings at all.

The Cincinnati CL post always drew an "incomplete final rapid sequence"
warning because it never declared IPostVerificationSupport. It writes etch
features before cuts, inserts or drops rapids, and with part sub-programs
rapids to each part's corner, so it cannot declare it unconditionally.
IPostVerificationSupport gains a nest-aware PlacedProgramOrderChange(nest)
(null = preserved; otherwise the reason, shown in the warning). The CL post
answers it from its own writer: part sub-programs and smart rapids off, and
every part's and hole's posted motions exactly equal to its placed ones.
Plan Cutting cuts scribes first, so planned nests qualify. CNC output is
unchanged.

A tabbed outside cut is trimmed short of its entry, but the trim only
handled lines and arcs: a round part's outline is one circle, so it was
cut whole. Plan Cutting counted it as tabbed and called the plan ready,
then the pre-post review found no tab and warned that the part may tip.
Cut a tabbed circle as an arc that stops the tab's chord short of its
entry, travelling the circle's own way.

The "Your first nest" layout (the help's sample parts, Auto Nested on a
60 x 120 sheet over a 2 inch support grid) must plan without warnings,
with support tabs on and off.

Round holes are cut as sub-programs, which are never marked because they
may be shared, so the safest-route fallback could not raise the head for
the rapid into a hole: on interlocked layouts every such crossing stayed
a finding and the plan stayed unverified. A HEAD RAISE marker may now sit
directly before a sub-program call, raising the call's arrival rapid.
- Motion reader: a marked call raises its first rapid; each sub-program
motion records the part's own call that runs it.
- RaisedRapids marks the call when the crossing rapid is its arrival.
- Cincinnati CL keeps the marker with its hole call and writes M47 before
it; part sub-program dedupe now tells marked programs apart.
- CI Fiber raises before the hole's first G0.

Small parts on a coarse support grid (the help tutorial's 5 x 5 gussets
on a 2 inch grid) rest on one or two points, so no single tab could
steady them and every plan came back unverified. New cutting settings
now start "Tab alone holds parts up to" at 6; settings saved without the
field still read as 0, so existing settings keep their meaning.
