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.

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.

Ahead of the new laser schedule, three ways a post could silently cut
with the wrong process, and one way its settings silently reset:
- Cincinnati CL wrote no G89 when no cut library matched the nest's
material, thickness and gas (or no etch library for etch features),
so the controller cut with whatever library it loaded last. It now
refuses, unless the new "Require libraries" setting is turned off.
- Cincinnati CL declared G20/G21 from its own setting without comparing
the nest's units, so a metric nest posted 25.4x too large. It now
refuses a mismatch.
- CI Fiber posted any material missing from its table as the default
code (MSN), so stainless or aluminum ran with mild-steel technology.
A named, unmapped material is now refused; the default code covers
only nests with no material.
- Posts saved their settings beside their DLL, inside the install
folder a Velopack update replaces, so every update reset them to the
shipped defaults. Saves now go to %APPDATA%\OpenNest\Posts and the
shipped JSON only seeds them; constructing a post no longer writes.

Plate > Set as Default and Nest > Edit's Defaults tab only changed the
open nest, so new nests never picked up the values. Set as Default now
also saves the new-nest defaults, and the Defaults tab gains an opt-in
"Use these defaults for new nests" check.
Machine thicknesses can now set part and edge spacing. A nest takes them
when its material, grade, thickness or machine changes and when a release
creates it; BOM import seeds its groups from them. Spacing edited in the
same dialog stays, and only an untouched trailing sheet follows.

Clamps are physical fixtures that differ between machines, but one global
clamps.json served every machine, so a plasma table and a fiber laser could
not have different rails.
- MachineConfig.Clamps holds each machine's rail in the machine's units,
edited on a new Clamps tab in Tools > Machine Configuration.
- New and BOM import give a nest the rail of the machine they assign;
Nest > Clamps loads and saves the nest's machine's clamps. Each nest keeps
its own copy, so machine edits never move existing nests' clamps.
- At startup, while no machine has clamps, the legacy clamps.json (or the
server's shared copy) is copied once into the default or only machine;
with several machines and no default the user picks one.

The flat ten-row list squeezed the quadrant picker to 120x28 and gave no
hint of units or where the defaults are saved. Group the fields (General,
Plate Size, Quadrant, Spacing), lay the edge spacings out around a plate,
show in/mm suffixes, and convert the values when the units switch so a
48 in plate does not silently become 48 mm.
The footer says whether Save writes to this PC or the shared nest server,
and Save is disabled while the shared copy is read-only instead of
failing after the click.
