Kernel: split a body by a plane or another face's surface

2026-10-08 17:31:57 +00:00

blend_corner.rs

Fillet corners: a radius per edge (kernel::fillet_radii), rounds next to earlier rounds of another radius, and smooth corner patches where three rounds meet

2026-10-08 22:37:29 +00:00

blend_variable.rs

Variable-radius and chord-length fillets

2026-10-08 21:30:58 +00:00

blend.rs

Fillet corners: a radius per edge (kernel::fillet_radii), rounds next to earlier rounds of another radius, and smooth corner patches where three rounds meet

2026-10-08 22:37:29 +00:00

body.rs

Face colours and opacity in STEP and 3MF export (and STEP import)

2026-10-08 14:02:10 +00:00

build.rs

Lofts through three or more sections are smooth: each side is one B-spline surface through every section (the middle sections leave no edges); two sections stay ruled

2026-10-08 13:48:12 +00:00

coplanar.rs

Booleans: prisms along one direction combined exactly in 2D (overlapping holes in plates; equal sections stacked end to end), bodies touching along one whole face stitched (a part joined with its mirror image), pushing coincident faces works with any plane-and-cylinder neighbours

2026-10-08 04:53:49 +00:00

curveblend.rs

Fillets and chamfers along open chains of curved edges that end at planar faces square to them (the round edge of a D-shaped block): the end faces take the blend's end arcs and their edges stop at the contacts; the curved blend is tried only for curved edges or edges between curved faces, and refuses a blend larger than its neighbouring faces

2026-10-08 08:32:45 +00:00

delete_face.rs

Fillet corners: a radius per edge (kernel::fillet_radii), rounds next to earlier rounds of another radius, and smooth corner patches where three rounds meet

2026-10-08 22:37:29 +00:00

freeform.rs

Exact profiles for splines of any degree (a degree-4…7 Bézier segment kind, Seg2::Bezier, extruded as B-spline edges) and for free-form curves cut by crossings (exact sub-curves whose ends are moved to the true crossing, found by Newton; polylines only where that fails)

2026-10-08 09:42:34 +00:00

heal.rs

Blends: whole smooth loops picked by one edge (tangent chain), full circles, walls at any angle, several loops per feature; flat non-plane faces healed into planes; fillets and chamfers repeat in feature patterns

2026-10-08 00:30:38 +00:00

helix.rs

Modelled threads (Thread with modeled: true): the ISO 68-1 profile cut along a helix, M3 to M20, on shafts and in bores; running out past a free end of the face, stopping square at a set length. The groove is a watertight screw-sweep mesh (kernel::sweep_helix_mesh) cut by kernel::faceted_boolean (BSP on the faceted body, tolerance ladder checked by A−B + A∩B = A); the polygon rebuild welds vertices across grid cells, splits pinched loops, finds T-junctions through a grid, and takes the group's plane for a loop a hair off flat

iges_in.rs

IGES 5.3 import and export; OBJ import; STL reading hardened

2026-10-08 15:17:25 +00:00

lib.rs

Construction axes, points and planes from model geometry (SOLID ▸ CONSTRUCT): axes through a cylinder/cone/torus, perpendicular to a face at a point, through two planes, two points or an edge; points at a vertex, through two edges, three planes, at the centre of a circle/sphere/torus, at an edge and a plane, along a path; midplane, planes through two edges or three points, tangent to a face, along a path. References (doc::construct::GeoRef) keep picked faces and edges by persistent name and resolve on each evaluation (they follow the model); results live in ModelState.construct, in the component's frame; view::construction_axes/points/planes for the viewport; kernel::face_surface for a face's analytic surface

2026-10-09 12:47:56 +00:00

loopblend.rs

Fillets and chamfers on runs of neighbouring edges along a planar face's loop (two or three top edges of a box): the blends meet in mitres at the sharp corners between them and end square where unblended edges go on (those edges and the walls' seams stop at the blend)

2026-10-08 11:31:27 +00:00

measure.rs

Measure: split triangles that cut through curved faces onto the surface (trimmed faces after booleans were measured up to 15% off; 61's keyway volume now matches); oracle step check shows the original volume

2026-10-08 02:48:17 +00:00

meshbody.rs

2026-10-08 15:17:25 +00:00

offset.rs

Construction axes, points and planes from model geometry (SOLID ▸ CONSTRUCT): axes through a cylinder/cone/torus, perpendicular to a face at a point, through two planes, two points or an edge; points at a vertex, through two edges, three planes, at the centre of a circle/sphere/torus, at an edge and a plane, along a path; midplane, planes through two edges or three points, tangent to a face, along a path. References (doc::construct::GeoRef) keep picked faces and edges by persistent name and resolve on each evaluation (they follow the model); results live in ModelState.construct, in the component's frame; view::construction_axes/points/planes for the viewport; kernel::face_surface for a face's analytic surface

2026-10-09 12:47:56 +00:00

ops.rs

Booleans about twice as fast: point-in-mesh tests through a per-direction grid (sampling checks), one mesh of the result for both its volume and membership checks, operand volumes from their meshes, and the intersection tried at the coarser tolerance first (oracle run 10 → 5 minutes); free-form faces merge in the topology counts when their normals agree within 2.5°

2026-10-08 10:46:13 +00:00

polybool.rs

Modelled threads (Thread with modeled: true): the ISO 68-1 profile cut along a helix, M3 to M20, on shafts and in bores; running out past a free end of the face, stopping square at a set length. The groove is a watertight screw-sweep mesh (kernel::sweep_helix_mesh) cut by kernel::faceted_boolean (BSP on the faceted body, tolerance ladder checked by A−B + A∩B = A); the polygon rebuild welds vertices across grid cells, splits pinched loops, finds T-junctions through a grid, and takes the group's plane for a loop a hair off flat

2026-10-09 12:47:56 +00:00

polyhedron.rs

Press Pull on a fillet's or chamfer's face edits that feature's size by the distance (found through the face's persistent name); on another curved face it offsets the face, with the rest of its surface (both halves of a hole's wall)

2026-10-08 13:39:34 +00:00

prism.rs

Kernel: clippy

2026-10-08 04:53:49 +00:00

provenance.rs

Provenance of sweeps and lofts: swept_origins (start cap in the profile's plane, walls by the profile segment under their start edge, end caps) and sweep_origins for sweep_path tools (walls in profile order, once per station), cross-checked in tests

2026-10-08 22:16:41 +00:00

sew.rs

Sheet metal: rules as expressions (Thickness, K-factor, bend radius, reliefs, gaps; may use parameters), sheet bodies kept as flat patterns and sewn folded from exact faces (new kernel::sew), Flange (base, edge with height to the outer face, angle, inside/outside/middle, several edges at once with corners closed to the rule gap, contour from an open chain), Hem, Unfold/Refold with cut-outs that follow the bends, Convert to Sheet Metal, flat pattern with bend lines and bend table, DXF export; recipes: sm_flange, sm_hem, unfold/refold, rule edits (oracle 67-76 all pass)

2026-10-08 04:11:35 +00:00

splitface.rs

Fillet corners: a radius per edge (kernel::fillet_radii), rounds next to earlier rounds of another radius, and smooth corner patches where three rounds meet

2026-10-08 00:16:52 +00:00

surface_kind.rs

Construction axes, points and planes from model geometry (SOLID ▸ CONSTRUCT): axes through a cylinder/cone/torus, perpendicular to a face at a point, through two planes, two points or an edge; points at a vertex, through two edges, three planes, at the centre of a circle/sphere/torus, at an edge and a plane, along a path; midplane, planes through two edges or three points, tangent to a face, along a path. References (doc::construct::GeoRef) keep picked faces and edges by persistent name and resolve on each evaluation (they follow the model); results live in ModelState.construct, in the component's frame; view::construction_axes/points/planes for the viewport; kernel::face_surface for a face's analytic surface

sweep_path.rs

Clippy: assign operators in the path sweep, isocurve grid and centre of mass

2026-10-08 09:42:34 +00:00

tests.rs

Topology counts: a horn torus pinched to a point is one face (smoothness ignores an edge's ends and points without a normal), with a degenerate loop at the pinch counted as Fusion does (two edges and a vertex); oracle 50 passes, 76/76

2026-10-08 15:41:02 +00:00

thread_tests.rs

Modelled threads (Thread with modeled: true): the ISO 68-1 profile cut along a helix, M3 to M20, on shafts and in bores; running out past a free end of the face, stopping square at a set length. The groove is a watertight screw-sweep mesh (kernel::sweep_helix_mesh) cut by kernel::faceted_boolean (BSP on the faceted body, tolerance ladder checked by A−B + A∩B = A); the polygon rebuild welds vertices across grid cells, splits pinched loops, finds T-junctions through a grid, and takes the group's plane for a loop a hair off flat
