step_in

IGES reader checked against Fusion's IGES exports: 75 of 76 reference parts read back exactly; cone tips read whole

2026-10-10 05:56:53 +00:00

blend_corner.rs

Join chamfers across unequal sloped rim walls

2026-10-11 01:37:06 +02:00

blend_variable.rs

Variable-radius fillets through middle points: radii at positions along the edge, straight or smooth between

2026-10-10 06:06:33 +00:00

blend.rs

Join chamfers across unequal sloped rim walls

2026-10-11 01:37:06 +02:00

body.rs

fix: load designs off-thread and cache recent thumbnails as PNGs

2026-10-10 20:55:14 -04:00

build.rs

A sweep along a path with sharp corners follows the corners: sweeping a rim profile along three lines (an open rectangle) gave a body of volume -0.0006 mm3 with its centre of mass at x = -3.5e9, and no error

2026-10-10 17:57:34 -04:00

coplanar.rs

No panics in the boolean's final assembly (the web build aborts on any panic: the Plastic Enclosure sample panicked 8 times and crashed the browser's start page); face pushes check their result and fall back to the general offset (a boss standing on a plate joins again with off-axis cylinder seams); offset errors name the face they can't move; docs/robustness.md with the before and after rates; caught panics counted per design in the robustness runs

2026-10-10 00:04:37 +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

fuzz.rs

Robustness runs and the kernel fixes they found

2026-10-10 00:04:37 +00:00

heal.rs

A panic while healing a boolean result no longer ends the boolean: a shallow, wide loft cut from a top face (556.68 x 99 down 4 mm to 80 x 80 in a 900 x 480 x 160 slab) failed with "called Option::unwrap() on a None value"

2026-10-10 17:57:34 -04:00

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

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

iges_in.rs

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

iges_out.rs

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

lib.rs

Fix modelling regressions and reconcile WIP UI work

2026-10-10 15:37:00 -04:00

lip.rs

Lips on rounded, shelled rims: the band along the rim's edge is raised from the body's own faces (kernel::raise_band: the rim face split along the band's exact offset edge, the band's walls swept up from the walls below, a top), since a join can't merge walls that continue each other; grooves cut with a band reaching into the free side so no wall coincides; tests against the band's area times its height

2026-10-10 00:04:37 +00:00

loopblend.rs

Join chamfers across unequal sloped rim walls

2026-10-11 01:37:06 +02:00

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

fix: load designs off-thread and cache recent thumbnails as PNGs

2026-10-10 20:55:14 -04:00

offset.rs

Shell refuses a wall thicker than a rim instead of returning a corrupt body: the topology-preserving face offset now checks every planar face's moved loops, and a loop that turns inside out or two loops that cross (a rim or ledge narrower than the move, e.g. a bowl opening sliding past the slab's outer edge) is an error naming the spot. Before, the self-crossing cavity went into the boolean and the shelled body came back with roughly twice its volume and its centre of mass outside the body, so every later cut failed its volume check

2026-10-10 12:32:03 -04:00

ops.rs

fix: reject planar joins that displace original faces

2026-10-10 22:53:44 -04:00

polybool.rs

A failed boolean no longer blames "coincident faces on curved bodies" whatever the cause: the exact polygon fallback runs after any failed B-rep boolean (faces that touch, or cross at a shallow angle) and takes planar faces only, but its refusal named coincident faces and curved bodies regardless. It now says which operand is in the way and why: "the tool has 2 curved faces (cylinder)" (kinds: cylinder, cone, sphere, torus, freeform), a face that could not be meshed, a planar face whose mesh is not flat, or a mesh too detailed. Test: planar_fallback_names_the_curved_faces

2026-10-11 10:25:10 +02:00

polyhedron.rs

Shell of rounded parts (the first tutorial): a round thinner than the shell collapses to a sharp inner edge (as in Fusion) instead of failing; when an open face's tangent round can't follow it out, every face moves in and the opening is the open face's copy swept out through the body; spindle tori (a bottom round running round a rounded corner) are taken by the offset; shells after a drilled hole; engine tests against the analytic volumes (box with rounded vertical edges and bottom loop, the tutorial plate at 2 mm and 1.5 mm)

2026-10-10 00:04:37 +00:00

prism.rs

fix: join connected solids at exact edge contacts

2026-10-10 23:11:02 -04:00

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

fix: join connected solids at exact edge contacts

2026-10-10 23:11:02 -04:00

splitface.rs

fix: load designs off-thread and cache recent thumbnails as PNGs

2026-10-10 20:55:14 -04:00

step_out.rs

Faces split on purpose stay split: the body remembers its Split Face lines, export and healing keep the pieces apart

2026-10-09 21:31:16 +00:00

step.rs

STEP export: AP242 file of our own, names, colours, components as assemblies

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

surfaces.rs

2026-10-10 20:55:14 -04:00

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

A failed boolean no longer blames "coincident faces on curved bodies" whatever the cause: the exact polygon fallback runs after any failed B-rep boolean (faces that touch, or cross at a shallow angle) and takes planar faces only, but its refusal named coincident faces and curved bodies regardless. It now says which operand is in the way and why: "the tool has 2 curved faces (cylinder)" (kinds: cylinder, cone, sphere, torus, freeform), a face that could not be meshed, a planar face whose mesh is not flat, or a mesh too detailed. Test: planar_fallback_names_the_curved_faces

2026-10-11 10:25:10 +02:00

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

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

topo.rs

Measuring bodies of thousands of faces: 13 s to 0.8 s for 5000 faces (the body's size was recomputed for every face); merged topology counts right on finely faceted bodies (vertices welded only when they coincide, planes merged only when parallel within 1e-9), with a test
