A clip box hides everything outside a user-controllable oriented bounding box, with cross-section caps drawn where IFC product geometry intersects the planes. The box is hosted on a Blender empty (CUBE display); its matrix_world is the single source of truth — G/R/S edits the empty and the viewport clip planes track. State persists through IFC save/load via a project-level pset (IfcProject.BBIM_ClipBoxes) so the boxes survive without binding to any IfcRoot entity (avoids the IFC scale-lock / strip). UI: BIM_PT_clip_box under the Sandbox tab. Prominent Enable Clipping + Show Caps toggles at top, then Add, then a UIList with per-row duplicate / remove icons. Scene-level enabled / show_caps so the "hide everything outside" intent applies file-wide; enabled is intentionally not persisted to the pset so reopening an IFC never silently hides geometry. Adding a clip box arms clipping so the user immediately sees the cut. Default spawn at the 3D cursor with scale 10 (a 20 m cube) so the volume covers a typical building storey or two rather than the meaningless 2 m unit cube. Modal-aware: depsgraph + draw-handler paths gate per-frame side effects on tool.Blender.is_transform_modal_active so dragging G/R/S on the box only writes the pset once on commit, not per frame. Shift+D / Alt+D / Ctrl+Shift+D on a clip box gets adopted as a first-class entry via the collection-to-list sync. Cap eligibility is gated on IfcElement (walls, slabs, doors, …) so spatial structure (IfcSpace, IfcBuildingStorey, IfcSite) and annotations / grids never sprout solid fills at clip boundaries. Cap rebuild is debounced behind a 1 s quiet window so external gizmo drags (and any other burst of non-Bonsai depsgraph updates) collapse to one rebuild on release. Bonsai's own G/R/S keeps the snappy on-release feel via a modal-end fast-path. The relevance filter compares a per-Object matrix hash against a baseline so a plain selection click — which Blender quirkily flags as a transform update — doesn't churn the cache or flash the caps off. Edit mode short-circuits both the rebuild scheduler and the draw handler entirely. Caps use the evaluated mesh (modifier stack applied) and a session/matrix/clip-box-hash cache so a typical scene only re-bisects meshes whose geometry actually changed. Performance: every per-frame poller (refresh, depsgraph handlers, draw handlers) short-circuits on the cheapest available check first — cap_cache emptiness for the post-view draw handler, scene_props.enabled for the rest — so a session with clipping disabled pays only one boolean read per tick. Known v1 limitations documented in tests / docstrings: hollow profiles cap as solid discs (single-ring tessellation only), non-watertight inputs may produce degenerate caps, quad-view untested, Cycles / EEVEE render not supported (GPU-overlay only).
