On an enclosed machine a cutout slug that tips once cut free can stand up
above the sheet and catch the enclosure door when the pallet changes. The
head already keeps off cut cutouts, so this is about clearing the door, not
the head.
Cutting Settings > Cutouts > "Slice slugs the support grid can't hold
level" (CuttingParameters.SliceTippingSlugs, off by default, saved per
machine thickness and written only when on) makes Plan Cutting cut each
such slug along the bed's contact lines (grid rows and columns, slat center
lines) before the cutout, so no piece keeps a contact and the pieces drop
between the supports. Each slice stops a kerf short of the cutout, so the
pieces stay attached until the cutout's own kerf frees them together. A
slug the bed holds level, or one on no contact, is left whole; a cutout
holding another part or another of its part's cuts is never sliced.
Slices are break cuts emitted right after the drawing's own break cuts,
pierced on themselves and led straight back to their start. The
released-contour proof now leaves out straight break cuts lying wholly
inside one of the part's closed holes, since the grid cells they free are
scrap; break cuts in material still take part. The plan fingerprint only
changes when the setting is on.

Finding a part on the nest server meant scrolling 40k drawings: the library
could only match an exact thickness or customer and knew nothing about a
drawing's size or holes. The library browser gets a Filter dialog with
inclusive ranges, and the query API takes them.
The server never parses packages and stays off IO, so the server worker now
measures each package beside its nest jobs (bounding sides, net area, closed
cutouts inside the outline) and stores the summary keyed by package hash
(schema v19). Identical geometry is measured once, an unreadable package is
recorded once instead of retried forever, and size or hole limits match only
measured drawings. Thickness ranges compare in inches across units and keep
the library's rule that a drawing saved without a thickness suits any.

The File menu ran six output commands together with no separators, and
"Export" / "Export All" didn't say what they exported. Group them by what
they produce:
- Save Copy as .nest File... (was Export .nest...) moves next to Save As,
since it writes the nest file rather than exporting a plate.
- Export Plate... / Export All Plates... (were Export / Export All) get their
own group and the "..." their save dialogs call for.
- Nest Report... / Part Printouts... (were View ...) form a reports group.
- Storage Mode... gets its own separator above Exit.
Export Nest Report... is removed: the report viewer already has Save As
(available even without WebView2), so it was a second path to the same PDF.
Its guard and failure tests now drive the viewer path, and the atomic-write
test calls WriteNestReport directly. The Avalonia prototype's matching
command is renamed too.

A part printout showed the part but not its size on the drawing, so the
operator had to read the table to know which way was which. Each page now
draws the overall X extent below the part and the Y extent to its right,
as the Shape Library does: arrows, a boxed label and extension lines that
stop 6 pt short of the outline itself rather than its bounding box.
Each dimension line moves out far enough to keep its label 14 pt clear of
the part (a wide label centered on an 18 pt line nearly touched it), and
the part and its dimensions sit 28 pt inside the drawing border, double
the old padding.

The nest report already leads its thickness with the machine config's
Name / Gauge; the part printout's THICKNESS cell now does the same
(16 ga - 0.0598"), from the same lookup in the desktop.
Thickness names are typed into the machine config, so both writers now check
them against the bundled font's Latin-1 limit like other free text, instead
of failing partway through rendering.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Thicknesses saved before the auto-fill kept a blank Name / Gauge until someone
edited their value, so their nest reports showed only the decimal. Opening
Machine Configuration now names every blank thickness that matches a standard
gauge or plate fraction and marks the form changed, so closing offers to save
them. Thicknesses matching none stay blank, and once saved a reopen finds
nothing to fill and does not ask again.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Reports now take a thickness's name from the machine config, so a blank
Name / Gauge leaves the report with just the decimal. Machine Configuration
now fills a blank name from the standard steel gauge or plate fraction table
when the thickness value changes, and keeps following the value while the
name is still the old value's standard one; a typed name is never replaced.
A new thickness starts named for its default 0.25 (1/4").
Existing blank names are not filled on open, so viewing a machine never marks
it dirty; editing the value fills them.

Each machine thickness already has a Name / Gauge field the shop fills in, so
the report now shows that name instead of guessing one from the standard
gauge table. It is matched the way the machine cutting defaults match the
nest's material, grade and thickness; a thickness without a name shows just
the decimal.

The generated date sat among the summary's report details and printed a UTC
offset nobody on the shop floor reads. It now goes in every page's footer,
left of "Page X of Y", in the computer's own time zone without the offset.
The thickness now leads with its gauge or plate fraction ("16 ga - 0.0598 in")
when it matches one, as the thickness box lists it. Reporting references Core
only, so the desktop looks the name up in StandardThicknesses and passes it on
the snapshot.

Shops used CutSend to get a part printout (the part drawn to fit a Letter
page over a details table) because OpenNest had no way to make one. File >
View Part Printouts prints every part drawing of the nest, and the drawing
list's View Part Printout prints one; both open the report viewer to save
or print.
Cut length and pierce count walk the program as it is cut, so etch marks,
tab spans and display-only moves add neither, a tabbed cutout counts one
pierce per piece, and breakoff and common-line cuts count. The drawing list
item reaches the main window directly so nests made by BOM import get it
too. Rendering shares the nest report's lock, fonts and Latin-1 limit.

The rules behind the WinForms MachineSettings and SharedSettings move into
OpenNest.Desktop as MachineSettingsSource and SharedSettingsSource, so the
Avalonia app reads machines, clamps and nest defaults the same way: in
Database mode the nest server's copy once it holds one (machines as a
whole, nest defaults and clamps as single documents), otherwise this PC's
files; the copy is re-read after two minutes (one while offline), and while
the server is unreachable the last copy read is used, read-only. Legacy
clamps still move onto the defaults' or the only machine once, asking at
most once per session, and cutting settings edited for a nest still save
onto the machine's thickness, or this PC (stamped for that job when the
machine cannot be saved).
Nothing in the shared code shows UI: it returns the warning texts, takes
the clamp-machine question as a delegate and reads the DefaultUnit and
CuttingParametersJson settings through IMachineUserSettings (with a
user-settings.json implementation under the WinForms names). Cut-off
defaults take CutOffSettings instead of a PlateView. MachineSettings and
SharedSettings stay in the WinForms project as thin wrappers with the same
members, showing the same dialogs and reading Properties.Settings and
NestStorage as before, so their callers are unchanged.
Tests cover File vs Database mode precedence, the offline read-only copy
and its once-per-session warning, staleness and retry timing, uploads,
post settings, legacy clamp migration, the cutting-settings save and the
user-settings file.

The Avalonia app applies the colour scheme saved as ActiveColorScheme in
the shared user-settings file when the main window opens, and recolours a
nest's drawings from it when opening the nest, as WinForms does.
The plate canvas draws the background, sheet, edge spacing, etch, part
outlines and selection from the active scheme through SkiaSchemePalette,
a cache of Skia colours rebuilt when the scheme's colours change, instead
of hard-coded colours. Part outlines follow the scheme's outline colour
or the fill darkened as WinForms darkens it. There is no Options screen
to change the scheme yet.

Master added head-raise markers, common-line shared cuts and remainders to
the CI Fiber's own contour extractor, which this branch replaced with Core's
shared PostContours. Those now live in the shared model: PostContour carries
Raised, IsCommonLine and RemainderWinding, and Classify gives remainders the
perimeter macro on their perimeter's side and shared cuts no kerf side.
ContourWinding uses PortableMath for trig, as master's Core guard requires.

The CL post wrote the configured default side (G41) on every contour,
so a contour wound against OpenNest's convention was compensated into
the part. It now takes each feature's side from Core's shared
PostContours winding rule, as the CI Fiber post does: the perimeter is
picked across the part's cut features and hole sub-program contours
are always holes. Correctly wound drawings post unchanged.
Remove the "Default kerf side" post setting; saved configs that still
carry it load as before. Expose PostContours.Flatten and Classify so a
post can classify one part's features itself.
Add CL tests for a square with a hole: the exact inline program, cuts
that match the shared contours on the sheet, G41/G42 keeping the part
out of the kerf inline and through part sub-programs, and identical
output from absolute and incremental part and hole programs. The
replay now records the compensation in force on each cut.

Move the CI Fiber post's contour extraction and winding into Core as
OpenNest.CNC.Posting.PostContours and ContourWinding, so every post can
take sheet- or part-frame contours with the perimeter and kerf side
already chosen instead of re-deriving them. CI Fiber now writes from
the shared model; its golden output is unchanged.
Scribe marks are never picked as the perimeter and get no kerf. A cut
that resumes after suppressed moves starts a new contour where they
end, so it is no longer cut as a chord across the gap.
Add tests for a square with a hole in sheet coordinates, identical
contours from absolute and incremental part/hole programs, rotation,
and the kerf side for both windings.

Shift+click in Clone Parts always kept whichever axis order landed the
copy nearest the origin, which can park it in a pocket the user didn't
want. Options > Clone push placement now picks Closest to origin (the old
behavior, still the default), Push left then down, or Push down then left.
Ctrl+click settles the copy on bounding boxes alone, so it stops square
to its neighbors' boxes instead of nesting into their shapes. Shift+click
keeps its box pass then geometry settle; both follow the chosen order.

On a plate packed edge to edge, an overlap left by hand-placing extra
parts could not be fixed: straight push chains ran into the edge and
the relaxation gave up on pairs that share material, which have no
contact normal. The relaxation now pushes such a pair along its
shortest straight way out and lets the rest settle, which cleared a
0.92 sq in overlap on a 38-part plate with every part kept square.
When moves alone still cannot settle, the relaxation runs again as a
rigid one: an off-center push also turns a part, up to 3 degrees, if
its drawing is free to rotate. Moves stay first because a tilt turns
every part the push reaches.

Expand Spacing opens up a whole selection; nests that are a hair short
of fitting need the opposite: move only the parts the overlap check
flags, by the shortfall, and leave everything else where it is.
Fix Spacing pushes one part of each flagged pair straight away from the
other and ripples the push into neighbors it crowds, so rows already
locked in at the spacing can make room. When a plate is packed edge to
edge and no straight push fits, a constraint relaxation shares each
shortfall between both parts along the closest-point normal. Every
result is confirmed by the overlap check before any part moves, and is
applied only when it has fewer findings and nothing new.
NativeContours gains a coarse-flattening overload, Translated, Nested
and a closest-points GapTo for the search.

Auto Nest left N26-2A5 (14 door stops, 14 lock plates on a clamped 26x26
sheet) 8.0 high, while the shop's hand layout holds all 28 under 7.5 and
leaves a half-inch-deeper drop. Every MaxRects fit rule packs into the
whole sheet, so with room to spare it spreads the parts out and never
looks for the shortest strip.
When a rule places all the remaining demand, Rectangles now repacks it
into shorter and narrower bins, every rule and mode per probe, and offers
the tightest complete layout per axis to the stock loop, which still
picks by cost and offcut. Fit is not monotonic in bin size (7.5 packs,
7.62 and 7.74 do not), so probes walk down through stack heights (sums of
spaced part sides from the bin edge or a reached clamp) instead of
bisecting. A placement budget skips sheets finishing ~2000+ parts.
Benchmark, Rectangles on 80 recent production nests with salvage credit:
11 cheaper, 0 worse, all valid, total time 14.7 s -> 13.2 s.
The zero-clamp hash is re-captured (the squeezed layout is narrower);
the far-clamp test now compares poses, since the clamp can reorder an
identical layout.

Operators reading a printed nest report could not see where the machine
clamps sit or which ones must be pulled before cutting, and had no way to
measure positions off the layout. Plate diagrams now draw active clamps as
hatched rectangles (labels keep clear of them) and removed rail clamps as
dashed, crossed-out rectangles over the parts, with a legend line only on
plates that have clamps. A horizontal ruler below and a vertical ruler left
of the drawing read the sheet's plate coordinates in job units; the
diagram is fitted in two passes so the ruler bands match their numbers,
and part labels never enter them. Rulers draw as their own content stream
so the diagram stream holds only the sheet and what is on it.

The shop needs each sheet's weight for handling, so the summary's plates
table gains a Sheet weight column: one full sheet from its area, the nest
thickness and the nest (or catalog) density. A drawing's own material is
not used, since it doesn't say what the stock is; with no density the
column is left out.
Plates with copies now put the total cut time (and total weight) on a
second line instead of after a comma, which wrapped mid-phrase.

Fill paired a 9" angle bracket at 90/270 degrees (75 on a 48 x 96 plate)
while a hand-laid herringbone at 315/135 holds 84. Its pair touches only at
the legs' ends, so it ranked ~888th by pair box area, and pairs are tiled
at the pair's own hull angles, never the part's 45-degree edge.
The pairs phase now also builds herringbone pairs: the part turned so a
hull edge lies along a sheet axis, its 180-degree copy slid onto the row
the part makes along that axis, tiled and remnant-filled like best-fit
pairs. Fill now finds the 84.
The chevron in the learned-angle fixture became a herringbone whatever
angles were learned, so a cross replaces it; the learned-angle and Strip
mixed nests are re-pinned.

Fill tiled 8" gussets on a 16.85 x 60 strip as seven pairs in a 10.35"
column (14) and left a strip too narrow for a gusset square on. Sliding
each pair along its hypotenuse so six span the height narrows the column
to 8.75" and leaves a strip that holds eight more turned 45 degrees (20),
as laid out by hand.
- The pair remnant filler tries strips down to the part's narrowest hull
width and tiles single best-fit pairs as a grid there, taking the grid
only when it places more than the rows of pairs.
- After the pair filler's early exit it also tries skipped candidates
whose grid plus an optimistic leftover-strip estimate could still win,
keeping one only when it places more parts.
- The optimistic remnant bound counts parts by true area, not bounding
box, so interlocking parts no longer prune winning candidates.
The mixed Fill nest pin now places 34 instead of 33; the mixed Strip nest
keeps 35 with its L-shapes laid out differently. Both pass the layout check.

After the fill strategies, the winning layout's outermost row on each side
is pushed into the edge slack, slid toward one end, and copies of its end
part are slid in from the freed end. Lifting a staggered hexagon row straight
over the one below opens a notch where one more nests: a 7" hex cover on a
60 x 120 sheet now fills 181 instead of 180. The policy's comparer must
prefer the result and the requested quantity caps it.

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.

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 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.

The Irregular engine grows each sheet from one side, so parts that fit only
when the outer ones hug opposite edges never met: ten one-off brackets
(four tapered 112-inch bars, four gussets, two small plates) stacked three bars
on one sheet and took three 60 x 120 sheets where two hold them.
After the search, a sheet-reduction pass splits a complete single-stock plan
over one sheet fewer and packs each sheet edge first: large parts to the
corners (flush, most outline on the edges, thinnest across the sheet), small
parts into the gaps last, and one key part into the pocket between. Clamped
sides move in past the keep-outs so edge parts line up on one straight edge.
When no sampled orientation fits the key, ContactFit turns it by its contacts
(each overlap a linear constraint on dx, dy and rotation) instead of sampling
more angles; the exact no-fit free region then confirms the angle, so spacing
and validation are unchanged. That job now nests on two sheets, the middle bar
at 4.4 degrees; the repository benchmark jobs are unchanged.

Make Nests bound each tab it nested to its saved record but left the
tab's history off its save point, so the tab showed " *" and closing it
asked to save. Yes uploaded a second revision, and a release that had
already looked up that draft (the panel asks the operator to save and
close an open draft) then merged with If-Match on the old revision: the
server refused it, that group failed, no nest after it was saved and the
release was not recorded. End() then closed the leftover tabs through
the unsaved prompt, whose Yes the release lockout refused.
- Binding a released tab marks its save point (EditNestForm.MarkSaved).
- Make Nests re-reads each merge target and merges at the revision now on
the server; one saved while the release runs is still refused.
- End() closes the tabs it did not save without the prompt
(CloseDiscardingChanges), after taking them off the release list.

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.

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.

Copy and Cut paste through ActionClone, which added each clone to the plate
but never recorded the groups the sources were in, so a pasted common-line
pair came out as separate parts held to the part spacing. ActionClone now
reads the copied parts' groups when it starts (before Cut removes the
sources and their groups) and joins each paste's clones the same way, at the
source group's kerf.

Moving one member of a common-line group used to break the group, so a drag
or nudge silently undid a join. Selecting a member, by click or window, now
selects its whole group, so drag, nudge, push, rotate and align carry the
joined parts together and keep their shared spans.
Right-clicking a part now offers Join Common Line and Remove Common Line,
running the Plate > Arrange commands on the selection. A right-click on a part
keeps its selection (or selects it with its group) instead of clearing it, so
the menu has something to act on; a right-click on empty plate still clears.

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.

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.

The job it acts on is shown as Stopping and then Stopped, and the rest of the
app talks about stopping server jobs, so the button now says Stop Job too.
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.

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.

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.

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.
