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 Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
