# SolveCraft — instructions for agents
|
||||
|
||||
SolveCraft is a clean-room, open-source, pure-Rust parametric 3D CAD application in the style of
|
||||
Autodesk Fusion: sketches with a constraint solver, a parametric timeline of features, a B-rep
|
||||
kernel, and a desktop UI that agents can drive. Siblings with the same conventions live next to
|
||||
it in `storytold/`: `cadcraft` (AutoCAD-style, the closest relative), `photocraft`, `vectorcraft`,
|
||||
`gridcraft`, `designcraft`, `wordcraft`, `deckcraft`, `soundcraft`. Repos don't share code; when
|
||||
code is adapted from a sibling (MIT OR Apache-2.0) it is noted in ATTRIBUTION.md.
|
||||
|
||||
## Start every session here
|
||||
1. Read `plan/STATUS.md` (current milestone, next task), then the task in `plan/execution-plan.md`
|
||||
and the relevant `plan/architecture.md` section. Behaviour reference: `plan/fusion/`
|
||||
(`menu-tree.json` is Fusion's toolbar dump; `oracle/*/` are parts built in Fusion with their
|
||||
recipes and measurements).
|
||||
2. Kernel and library decisions: `plan/adr/0001-geometry-kernel.md` (what we may depend on, what
|
||||
is rejected for licence reasons).
|
||||
3. Follow the autonomous operation protocol (`plan/execution-plan.md` §6). Don't stop to ask
|
||||
unless it lists the decision as the owner's.
|
||||
|
||||
`plan/` is gitignored (local only).
|
||||
|
||||
## Never crash
|
||||
People trust SolveCraft with their designs; a crash loses their work. **This outranks feature work.**
|
||||
- **No panics in non-test code:** no `unwrap()`, `expect()`, `panic!`, `unreachable!`, `todo!`,
|
||||
`unimplemented!`; no `unsafe` (`unsafe_code = "forbid"`).
|
||||
- **Errors are `Result<T, E>`** through the crate's error type and `?`. An unfinished feature
|
||||
returns an error ("not supported yet: …"); it never panics.
|
||||
- **Input-derived numbers are hostile** (command parameters, design files, control-channel
|
||||
input): `get()` not `[i]`, finite checks, caps on sizes and loop counts.
|
||||
- **Third-party kernel calls are guarded:** everything that calls `truck` goes through
|
||||
`solvecraft_kernel::guard`, which turns a panic into `KernelError::Internal`.
|
||||
- **Last-resort guard:** `Session::execute` runs every command under `catch_unwind`; an escaped
|
||||
panic restores the design and reports `EngineError::Internal`.
|
||||
- **Prove it:** every crash fix lands with a regression test (see `hostile_params_never_panic`).
|
||||
- Every production crate root carries
|
||||
`#![deny(clippy::unwrap_used, clippy::expect_used, clippy::panic, clippy::unimplemented, clippy::todo, clippy::unreachable)]`.
|
||||
|
||||
## Non-negotiables
|
||||
- **Clean-room.** Fusion may be *observed* black-box (its UI, its toolbar dump, parts built in it
|
||||
and their measurements, kept under `plan/fusion/`, never committed). Never copy Autodesk icons,
|
||||
artwork, help text, tooltips, templates or materials, and never commit files produced by
|
||||
Fusion. Command ids and command names are used as identifiers only (`xtask/data/fusion-catalog.tsv`
|
||||
holds ids and names, nothing else). File formats come from public specifications. **Never read,
|
||||
copy or link GPL/LGPL/AGPL code**: OpenCASCADE, FreeCAD (incl. planegcs), SolveSpace,
|
||||
CadQuery/OCP, LibreCAD, QCAD — don't even read their sources. The sketch solver and the blend
|
||||
operations are our own.
|
||||
- **Assets — absolutely essential.** SolveCraft contains **no Autodesk iconography, images,
|
||||
fonts or artwork — ever.** Every icon is drawn in code (`crates/ui-egui/src/icons.rs`). Any
|
||||
file asset must be original or openly licensed and **must have a row in ATTRIBUTION.md**
|
||||
(`cargo xtask assets` enforces it). Screenshots of Autodesk software are never committed.
|
||||
Breaking this rule is the most serious mistake you can make in this repo.
|
||||
- **Everything is a command.** User-visible behaviour = a command in `crates/engine/src/cmd/*`
|
||||
(`CommandSpec`: id = Fusion's command id where Fusion has the command, else a dotted id; label;
|
||||
toolbar tab and panel; icon; shortcut; params doc; `enabled`; JSON `run`) + tests. The toolbar,
|
||||
dialogs, sketch tools, palette, scripts, CLI and control channel all reach the same commands.
|
||||
- **Programmatic calls never open dialogs.** `engine.execute` runs the JSON form; only toolbar
|
||||
clicks (`ui.start`) start interactive tools and dialogs, which then run commands.
|
||||
- **Layering** is enforced by `cargo xtask layers`: L0 `geom` → L1 `sketch`, `kernel`, `render`
|
||||
→ L2 `doc` → L3 `io` → L4 `engine` → L5 `ui-egui` → apps. Nothing below L5 depends on
|
||||
egui/eframe/winit/wgpu/rfd. **The UI crate is swappable.** Only `crates/kernel` may use `truck`.
|
||||
- **The UI is thin**: panels read engine state and act through `app.run(id, params)` /
|
||||
`app.start(id)`. Colours come from `theme::Tokens`.
|
||||
- **Rust only.** Units are millimetres and radians internally; Z is up.
|
||||
- **Quality gates** before every commit: `cargo xtask ci` (fmt, clippy -D warnings, tests,
|
||||
assets, layers). Commit after every feature arc that builds.
|
||||
- **Publishing**: `origin` is github.com/bherbruck/solvecraft (private). After each commit that
|
||||
passes `cargo xtask ci`: `git pull --rebase origin main` (re-run ci if it brought changes),
|
||||
then `git push`. Never force-push. Never commit `plan/`, build dirs (`target*/`) or anything
|
||||
produced by Fusion (oracle STEP/STL/PNG); check `git ls-files` before pushing.
|
||||
- **Never break wasm**: everything below the apps must build for `wasm32-unknown-unknown`
|
||||
(`cargo xtask wasm`, part of `cargo xtask ci`).
|
||||
|
||||
## Running and looking at the app
|
||||
- `cargo run --release -p solvecraft -- --sample --control PORT` (sample design + control channel).
|
||||
Pick a free port. Without a display, run it under `Xvfb :99` with `DISPLAY=:99`.
|
||||
- Drive it with JSON lines on `127.0.0.1:PORT` (see `docs/control-protocol.md`):
|
||||
- `{"id":1,"method":"engine.execute","params":{"command":"Extrude","params":{"distance":20}}}`
|
||||
- `{"id":2,"method":"ui.start","params":{"command":"SketchCreate"}}` then `ui.click {x, y}`
|
||||
- `{"id":3,"method":"ui.screenshot","params":{"path":"/tmp/shot.png"}}` then read the PNG.
|
||||
- **For UI work, look at the result** (screenshot, read the PNG). Without a window use
|
||||
`ui.render` or `solvecraft-cli snapshot`.
|
||||
- Headless: `solvecraft-cli run script.json --out part.step`, `solvecraft-cli eval design.solvecraft`,
|
||||
`solvecraft-cli snapshot script.json --out shot.png`, `solvecraft-cli commands`.
|
||||
- Fusion oracle: `cargo xtask oracle` replays `plan/fusion/oracle/*/recipe.json` and compares
|
||||
with Fusion's `measure.json` (writes `docs/oracle.md`).
|
||||
- Build with `CARGO_TARGET_DIR=<repo>/target`. Windows: `cargo xwin build --release --target x86_64-pc-windows-msvc -p solvecraft`.
|
||||
|
||||
## Roadmap

|
||||
milestone task lands. `cargo xtask parity` recomputes command parity in `docs/parity.md`;

# Attribution
|

|

Every non-code asset in this repository (images, icons, fonts, example parts) is listed here with

**Policy (mandatory):** SolveCraft contains **no Autodesk iconography, images, artwork, fonts,

third-party material under an open licence. Screenshots of Autodesk software are never committed.

Generated-in-code assets are original and have no file to list:

the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of

origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|

Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor

# SolveCraft
|
||||
|
||||
SolveCraft is an open-source parametric 3D CAD application written in Rust, in the style of
|
||||
Autodesk Fusion: sketch on a plane, constrain and dimension the sketch, turn profiles into solids
|
||||
with extrude and revolve, round edges, combine bodies, and change a parameter to watch the whole
|
||||
timeline rebuild. It is a clean-room implementation (see [CLAUDE.md](CLAUDE.md)) and part of the
|
||||
storytold "craft" family.
|
||||
|
||||
|
||||
|
||||
**Status: early (milestone M0 done, M1 in progress).** See [ROADMAP.md](ROADMAP.md),
|
||||
[docs/parity.md](docs/parity.md) (command parity with Fusion's Design workspace) and
|
||||
[docs/oracle.md](docs/oracle.md) (parts built in Fusion, rebuilt and measured in SolveCraft).
|
||||
|
||||
## What works
|
||||
|
||||
- **Sketches** on the origin planes, offset planes or planar faces: lines, rectangles (2-point,
|
||||
3-point, centre), circles (centre, 2-point, 3-point), arcs (3-point, centre), polygons, slots
|
||||
and points; construction geometry.
|
||||
- **Constraints and dimensions** solved by our own solver (damped Gauss–Newton with
|
||||
degree-of-freedom analysis): coincident, horizontal/vertical, parallel, perpendicular, tangent,
|
||||
equal, concentric, collinear, midpoint, symmetry, fix; linear, aligned, horizontal, vertical,
|
||||
radius, diameter and angle dimensions driven by parameters. Over-constraining edits are
|
||||
rejected; fully constrained geometry turns black.
|
||||
- **Profiles** found automatically, including regions split by lines and holes inside outlines.
|
||||
- **Features** on a parametric timeline: extrude (one side, flipped, symmetric, two-sided, start
|
||||
offset; new body, join, cut, intersect), revolve, fillet and chamfer (straight convex edges),
|
||||
box, cylinder, sphere, torus, combine, move. The timeline rebuilds incrementally from the first
|
||||
changed feature; it can be rolled back, and features can be suppressed, renamed, edited and
|
||||
deleted.
|
||||
- **Parameters** with unit-aware expressions (`2 * width + 5 mm`, `angle / 2`).
|
||||
- **Files**: designs as JSON (`.solvecraft`), export to STEP (AP242 with body names, colours and
|
||||
components as assemblies; revolved faces as native planes, cylinders, cones, spheres and tori), 3MF, STL (binary/ASCII) and OBJ;
|
||||
3MF and STL import as mesh bodies (they render, measure, move and export; solid features need
|
||||
B-rep bodies);
|
||||
STEP import (AP203/AP214/AP242 solids, assemblies, units, names, colours) as a base feature
|
||||
that later features build on — open a `.step`/`.stp` file, insert one into a design, or drop it
|
||||
on the window ([docs/step-import.md](docs/step-import.md)).
|
||||
- **Desktop app** (egui + wgpu): toolbar with workspace tabs, browser, timeline, 3D viewport with
|
||||
view cube and navigation bar, sketch tools, feature dialogs, command palette, and a JSON-lines
|
||||
control channel so agents and tests can drive it.
|
||||
- **Headless CLI** `solvecraft-cli`: run command scripts, measure (volume, area, centre of mass,
|
||||
face/edge/vertex counts), export, render PNG snapshots, replay Fusion oracle recipes.
|
||||
- **MCP server** `solvecraft-cli mcp`: AI agents model, measure and look at parts headless or
|
||||
in the running app (see below).
|
||||
|
||||
## Build and run
|
||||
|
||||
```sh
|
||||
cargo run --release -p solvecraft -- --sample # desktop app with a sample part
|
||||
cargo run --release -p solvecraft-cli -- commands # the command registry
|
||||
cargo run --release -p solvecraft-cli -- run examples/bracket.json --out bracket.step
|
||||
cargo run --release -p solvecraft-cli -- snapshot examples/bracket.json --out bracket.png
|
||||
cargo run --release -p solvecraft -- part.step # open a STEP file as a new design
|
||||
cargo run --release -p solvecraft-cli -- eval part.step # measure an imported STEP file
|
||||
cargo xtask ci # fmt, clippy, tests, assets, layers, wasm
|
||||
```
|
||||
|
||||
Windows builds: `cargo xwin build --release --target x86_64-pc-windows-msvc -p solvecraft`.
|
||||
|
||||
In the browser: `cd apps/solvecraft-web && trunk build --release --public-url ./` (WebGPU, or
|
||||
WebGL2 with `?webgl`; `?sample` opens the sample part).
|
||||
|
||||
## Scripts
|
||||
|
||||
A script is a JSON list of commands, the same ones the UI runs:
|
||||
|
||||
```json
|
||||
{"commands": [
|
||||
{"command": "SketchCreate", "params": {"plane": "XY"}},
|
||||
{"command": "ShapeRectangleTwoPoint", "params": {"p0": [0, 0], "p1": [40, 30]}},
|
||||
{"command": "Extrude", "params": {"distance": 20}},
|
||||
{"command": "FusionFilletEdgesCommand", "params": {"edges": [[0, 0, 10]], "radius": 3}}
|
||||
]}
|
||||
```
|
||||
|
||||
## AI agents (MCP)
|
||||
|
||||
`solvecraft-cli mcp` is a [Model Context Protocol](https://modelcontextprotocol.io) server on
|
||||
stdio. Headless it runs its own design session; with `--connect 127.0.0.1:PORT` it drives the app
|
||||
started with `solvecraft --control PORT`, so you can watch the agent model. Tools:
|
||||
`list_commands`, `execute`, `batch`, `inspect_design`, `measure`, `body_topology`,
|
||||
`set_parameter`, `screenshot` (returns the image), `export`, `undo`, `redo`, `new_design`, `open`,
|
||||
`save`. Claude Code: `claude mcp add solvecraft -- solvecraft-cli mcp`. Details, client
|
||||
configuration and an example session: [docs/mcp.md](docs/mcp.md).

# SolveCraft roadmap
|
||||
|
||||
Status as of **2026-10-07**. SolveCraft targets Fusion-style parametric modelling (sketch →
|
||||
features → parametric timeline) as an open, pure-Rust, agent-drivable application.
|
||||
|
||||
## At a glance
|
||||
|
||||
| Question | Answer |
|
||||
|---|---|
|
||||
| Where are we? | **M0 done; M1/M2 in progress.** Sketch with solver, extrude (taper, two-sided, through all), revolve, fillet/chamfer, holes, patterns, mirror, shell, draft, loft, sweep, split, construction planes, parameters that rebuild the timeline, STEP/STL export, desktop and browser (wasm) app with Fusion-style selection (hover/selected highlights, origin planes, click-to-pick sketch planes, multi-select, window/crossing box selection, animated view cube), CLI, MCP server, oracle harness. |
|
||||
| Command parity (in scope) | **139 / 541 (26%)** in-scope commands; SOLID + SKETCH **102 / 291 (35%)** — [docs/parity.md](docs/parity.md) |
|
||||
| Fusion oracle | **72 / 76 parts match** (batch 1: 29/29; batch 2 in progress) — [docs/oracle.md](docs/oracle.md) |
|
||||
| Tests | 85 (solver, profiles, kernel booleans/blends/measures, expressions, timeline, file formats, camera, engine end-to-end, hostile-input fuzz over every command) |
|
||||
| Gates | `cargo xtask ci`: fmt, clippy -D warnings, tests, asset attribution, layering, wasm32 build — green |
|
||||
| Weighted parity estimate | **≈ 5%** of Fusion's Design workspace by importance (sketch + basic solids are the core, but surfaces, assemblies, sheet metal, CAM, drawings are untouched) |
|
||||
| Time to a useful alpha (M0–M6) | ≈ **150 agent hours** remain |
|
||||
|
||||
## Scope (owner decision, 2026-10-07)
|
||||
|
||||
In scope, in priority order:
|
||||
1. SOLID and SKETCH (now).
|
||||
2. Parameters / functional constraints (done: see `parameters.*`, `expr.evaluate`; unit-aware,
|
||||
cycles reported with their path, rename follows references, deletes list their users):
|
||||
user parameters with units and expressions (+-*/, ^,
|
||||
parentheses, sin/cos/sqrt/min/max/floor/ceil/round, unit conversion), model parameters
|
||||
d1, d2… for every dimension and feature input, references between parameters with a
|
||||
dependency graph and cycle detection, re-evaluation on change, comments, favourites,
|
||||
CSV/JSON import and export.
|
||||
3. Components and assemblies with joints (M9).
|
||||
4. SHEET METAL: flange, contour flange, bend, unfold/refold, flat pattern with DXF export, sheet
|
||||
metal rules (thickness, K-factor, bend radius) (M10).
|
||||
5. A small PLASTIC subset for enclosures, after sheet metal: Boss, Rib, Web, Lip/Groove, Snap Fit.
|
||||
|
||||
Deferred until further notice: MESH, FORM (T-splines), SURFACE beyond what solids need, PCB / 3D
|
||||
PCB / Package, Render, Animation, Simulation, Manufacture/CAM, Drawings. The parity report's
|
||||
headline counts in-scope tabs only and lists the deferred ones separately.

|
||||
| M2 | Robust modelling: coplanar booleans in the kernel, holes (placed on faces and on sketch points), threads (cosmetic, then modelled), patterns, mirror, shell, draft, split, construction geometry | in progress | 16 |
|
||||
| M3 | General fillets and chamfers (curved edges, chains, vertex blends) | planned | 30 |

|
||||
| M5 | Persistent naming of faces and edges (plan/adr/0002): faces named from their history (sketch curve sides, caps, revolve sections, primitive sides, blends, pattern/mirror copies; split pieces numbered), edges by their faces; fillets/chamfers, sketches on faces, shell/draft/offset/replace faces, hole placements, joint origins and face appearances resolve by name first and warn when the entity split or vanished: done. Left: sheet metal edges, kernel-reported face history (exact through coincident surfaces), more roles (sweep, loft, shell inner faces) | in progress | 20 |
|
||||
| M6 | UI depth: selection feedback and origin (done), timeline editing (done: edit feature, history marker drag, reorder with dependency checks, suppress, rename, delete with dependents, re-resolved references), right-docked dialogs (done), live previews for every feature dialog (done), keyboard-first commands with on-canvas value boxes and sketch inline dimensions (done), drag manipulators with automatic join/cut (done: extrude incl. two sides, fillet, shell, hole depth, move, pattern spacing, revolve rotator; taper handle open), dark theme (done), right-click menu with Repeat (done), measure tool (done), section analysis (done), selection filter (done), drag-solve of sketch points (done); appearances, preferences | in progress | 6 |
|
||||
| M7 | Sweep, loft (incl. to a point), rib and web (to next / depth), emboss (planar faces), thread (cosmetic), coil (smooth B-spline helical walls), pipe, pattern on path, patterns of bodies and components, replace face (parallel), align, remove, feature copy/paste: done. Left: emboss on curved faces, thicken (needs surfaces), split face, modelled threads | in progress | 12 |
|
||||
| M8 | Surface workspace | deferred | — |
|
||||
| M9 | Components and assemblies (Fusion-style): New Component / Create Components from Bodies, active component, per-component origin/bodies/sketches/timeline entries, occurrences with transforms, Copy/Paste vs Paste New, nested Browser tree with visibility and isolate; Ground, Move/Copy of occurrences, joints (rigid, revolute, slider, cylindrical, pin-slot, planar, ball) by joint origins with limits and Drive Joints, As-built Joint, Rigid Group, Contact Sets (driving and motion studies stop where bodies in a set would pass through each other), Motion Study (joint values keyed along a timeline, playback, export of occurrence positions as JSON/CSV), Exploded views (automatic or by hand, shown without changing placements); interference, per-component physical properties; STEP with assembly structure. Groundwork done: component tree, occurrences with transforms (instances, Paste New), world placement, active component as authoring frame, ground, Capture/Revert Position, moving bodies and sketches. UI: ASSEMBLE panel dialogs for New Component, Joint (snaps on faces, edges, circles and vertices; animated motion preview; offsets, flip, limits), As-built Joint, Joint Origin, Rigid Group, Drive Joints (live slider), Motion Link and Interference (overlaps shown red); joints in the timeline and the Browser | in progress | 32 |
|
||||
| M10 | Sheet metal: flange (base, edge, contour), hem, unfold/refold, convert, flat pattern + DXF, rules: done (oracle 67-76). PLASTIC enclosure subset: Boss, Rib, Web, Lip/Groove, Snap Fit, Rest, Plastic Rules (library, edit, assign; rule draft and clearance as feature defaults): done, no Fusion oracle (licence), tested against hand-computed geometry. UI: SHEET METAL and PLASTIC tabs in Fusion's layout with dialogs (live preview, Edit Feature, pre-selection) for Flange, Hem, Unfold/Refold, Convert, Sheet Metal Rules, Create Flat Pattern (flat view with bend lines, bend table, DXF export), Boss, Lip/Groove, Snap Fit, Rest, Manage and Assign Plastic Rules; Bend (Fold) has no engine command yet | in progress | 36 |
|
||||
| M11 | 2D drawings | deferred | — |
|
||||
| M12 | Release: installers, signing, docs, performance | planned | 16 |
|
||||
| M14 | Configurations: a table of rows (parameter expressions and feature suppressions per row) switched with config.activate (undoable, all or nothing), kept through parameter renames and feature deletes (FusionStartDesignConfigModeCmd, FusionShowDesignConfigPanelCmd, config.column/row/activate). Left: configuration rules, per-row materials and appearances | in progress | 4 |
|
||||
| M13 | Never lose work: atomic saves (temporary file, flush, rename; a crash at any moment leaves the old file or the new one) with the replaced version kept as `<file>.bak`; autosave of unsaved changes to the recovery folder every 5 minutes (preference) and after big operations, only when something changed; "Recover unsaved design?" on the next launch (`doc.recovery_list`, `doc.recover`, `doc.recovery_discard`); a kill-mid-save test (process killed while saving a 0.5 MB design 25 times). File format: `"format": "solvecraft/2"`, older formats upgraded step by step (`doc::format`), newer ones refused with a message, out-of-range numbers and broken placements refused; a corpus of designs saved by M0, components-era, joints-era and current builds (apps/solvecraft-cli/tests/corpus) that must open and evaluate as saved; damaged and hostile variants (truncation, bit flips, hostile values, removed keys, repeated features, deep nesting) never panic | done | 6 |
|
||||
|
||||
## Known limitations
|
||||
|
||||
- Fillets and chamfers: straight edges (convex or concave) between planar faces with perpendicular
|
||||
planar end faces; whole smooth loops of a planar face, picked whole or by one edge (tangent
|
||||
chain), including circles and walls at any angle (boss bases and tops, bores, pocket floors,
|
||||
plate outlines), loops with sharp corners between straight edges (the blends meet in mitres), runs of
|
||||
neighbouring edges along a planar face's loop (two top edges of a box: mitred, ending square;
|
||||
with the edge between them too, the corner becomes a sphere octant),
|
||||
rounded corners rounded again (sphere octants, tori at concave corners); every edge of a
|
||||
convex planar body or of an extruded part; fillets inside patterns; closed chains of curved
|
||||
edges between any two smooth sides (a branch pipe on a main pipe), by a rolling ball (the
|
||||
blend a rational B-spline through exact arcs), closed or ending at planar faces square to the
|
||||
edges.
|
||||
- Booleans: prisms along one direction (plates with holes, slots, patterns of them, equal
|
||||
sections stacked end to end) are combined exactly in 2D; bodies touching along one whole face
|
||||
(a part and its mirror image) are stitched; coincident planar faces are pushed apart when
|
||||
their neighbours are planes or cylinders. Other coincident curved configurations can still
|
||||
fail. Fully internal voids are not supported. Spheres are built from six pole-free patches.
|
||||
- Mass properties come from fine tessellation (curved faces within ~1e-4 relative); triangles
|
||||
that cut through curved faces (trimmed faces after booleans) are split onto the surface first.
|
||||
- STEP import (our own reader, crates/kernel/src/step_in; all 29 Fusion STEP files pass
|
||||
`cargo xtask step-corpus`) reads solids (B-rep with analytic and B-spline geometry), units,
|
||||
product names, colours and assemblies; offset surfaces and pcurve-only edges are not read yet,
|
||||
and assembly components are flattened into bodies. Closed periodic faces (torus, B-spline
|
||||
bands) are split in two for meshing; measure() uses a finer tolerance for small radii.
|
||||
- No persistent naming (fillet edges are re-found by position; projected sketch geometry too).
|
||||
- Free-form curves cut at a tangent touch (no clean crossing) enter that profile as polylines.
|
||||
Sweeps along 3D sketch curves follow their polyline (smooth walls when the path is smooth).
|
||||
- Shell and offset faces work on bodies of planes, cylinders, cones and spheres (convex or not:
|
||||
filleted boxes, bosses, domes, countersinks); draft on convex planar bodies and on walls (planes, cylinders → cones) between caps; lofts through three or more sections are smooth (B-spline sides through every section), two
|
||||
sections ruled.
|
||||

# Design file corpus

Designs saved by older SolveCraft builds. `tests/design_corpus.rs` opens each one with the

current build and checks that it evaluates as it did when saved (the `.expected.json` next to
|
||||
it is `solvecraft-cli eval` of that file by the build that saved it: bodies, volumes, areas,
|
||||
world bounding boxes), that it is upgraded to the current file format, and that damaged and
|
||||
hostile variants of it never panic.

//! - 1: every design up to 2026-10-08 (format string since M0). Fields added over time all
|

//! have defaults; designs from before feature input names and before occurrences are filled
|
||||
//! in on upgrade.
|

//! - 2: the same shape; files say 2 once they have been upgraded, so later readers can tell.
|
||||
//! - 3: appearances per body, face and component with names and opacity
|
||||
//! (`"appearances": {"bodies": {name: {name, color, opacity}}, "faces": […], "components": {…}}`);
|
||||
//! before, `"appearances"` mapped body names to bare `[r, g, b]` colours.
