With support tabs on and no support bed, nothing was tabbed and nothing
said so. A new no-bed width range (NoBedTabMinWidth..NoBedTabMaxWidth,
the short side of the part's minimum-area bounding rectangle) now picks
the parts to tab instead. SupportTabSettings.Analyze makes the choice
for Plan Cutting, hand-placed lead-ins and the pre-post review; without
a bed any tab clear of inside corners counts. With no bed and no range,
the plan notes that nothing was tabbed. Cutting Settings > Tabs gains
the range fields, and the values persist with the cutting parameters.

Some jobs cut only cutouts into a supplied blank, such as instrument holes
in a purchased door that is the whole sheet. Its outline has to be known
to the planner (the blank is material that leads, rapids and cut-offs must
respect) but must never be pierced, led or cut.
A new DisplayPerimeter layer marks that outline. It is material, so
nesting, containment, lead clearance and automatic cut-offs all see the
blank; a door that fills its sheet leaves cut-offs nothing to cut. Cutting
preparation keeps it out of the contours entirely: with no cut perimeter
every contour is a hole with internal leads, and the search, best-effort
and safest-route paths stop offering a perimeter. Replay refuses any run
along the display perimeter and completes once every other ring is cut.
A display perimeter must be one whole closed contour enclosing every other
contour; a mixed ring, one inside another contour, or a second one is
refused with that reason. Saving, drawing and posting it are still to do.
Plan Cutting is now the only automatic lead-in assignment, and parts the
support grid cannot hold level are reported wherever they lack a
steadying tab.
- Remove Assign Lead-ins (plate and nest), LeadInAssigner, the lead-in
tool's Auto-Assign button and the Auto Tab size range; old settings
with autoTab sizes still load
- Manual Place Lead-in tabs the clicked entry when support tabs are on
and the grid cannot hold the part (SupportTabSettings)
- New PartSupport finding: Plan Cutting replay and best-effort plans
warn when a drawing pin, a lead-in that does not fit or no single tab
leaves a part unsteady; the pre-post review checks each placed
program's outside tab gap. These warnings replace the advisory
weak-tab notes; only the inside-corner tab note stays advisory, and
never for a pin
- Pinned perimeters keep their pin but carry the support analysis
- Draw grid points as pixel-snapped squares without anti-aliasing
- Post fixtures build lead-ins through a test-only TestLeadIns helper

The best tab point used to land in inside corners: equally good points
run along a straight edge, vertices were tried first and the first tie
won. Operators cannot grind a nub flush there.
- SupportAnalyzer finds inside corners (inward-turning vertex runs of at
least 30 degrees, so chorded fillets count) and keeps tab points a
clearance from them; of equally good points it picks the one farthest
from an inside corner. Plan Cutting and the overlay use twice the tab
size; AcceptsTabAt rejects closer points
- When no steadying entry has a lead-in that fits, the search falls back
to entries clear of inside corners, then to every entry, each ordered
by how well the tab steadies the part, keeping only the steadiest that
fit
- Replay notes parts whose planned tab cannot hold them level or sits in
an inside corner; the notes are advisory and leave a Ready plan Ready
- Console/MCP plate summaries print a ready plan's notes
- docs/support-tabs.md and cutting-planner notes

Model the machine's support bed as a grid of contact points measured
from the plate origin, and check each part's center of gravity against
the convex hull of the grid points under its material. The bed is
extensible so straight and CAD-imported curved slats can follow.
- Core: SupportBed/SupportGrid, SupportMaterial and SupportAnalyzer
(margin with registration tolerance, best single tab point)
- Nest-wide support bed that every plate follows, saved in
plateDefaults.supportBed; machine defaults in support-grid.json
- CuttingParameters.SupportTabs: Plan Cutting tabs only unsupported
parts and limits their perimeter entries to points where the tab
steadies the part, falling back to any fitting entry
- Desktop: Nest > Support Grid..., View > Draw Support overlay and a
"Tab parts the support grid cannot hold level" tab option
- docs/support-tabs.md, nest file format and planner notes
