Export: ExportCommand/CLI --out/MCP export with .3mf write a 3MF Core package ([Content_Types].xml, _rels/.rels, 3D/3dmodel.model; millimetres), one mesh object and build item per body, named after it, vertices shared and welded watertight (T-junctions between faces split), base-material colours when bodies carry one (STEP colours now ride on bodies). Tessellation as for STL. File > Export 3MF. Import: doc.open/drag-drop/CLI/MCP open accept .3mf and .stl; Insert Mesh (ParaMeshInsertAlignCommand) adds them to a design as a MeshImport feature. Kernel mesh bodies render, measure exactly, move and export; solid features refuse them with a clear error. 3MF reading flattens components and build transforms, converts units, reads colours; sizes, entries, nesting and element counts are capped.

# 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 (SOLID + SKETCH toolbar) | **57 / 291 (20%)** — [docs/parity.md](docs/parity.md) |
|
||
| Fusion oracle | **25 / 29 parts match** Fusion's measurements — [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 |
|
||
|
||
## Milestones
|
||
|
||
| # | Milestone | Status | Hours left |
|
||
|---|---|---|---|
|
||
| M0 | Vertical slice | done | — |
|
||
| M1 | Sketch depth, oracle sketch cases (arcs, taper, two-sided, sketch modify tools) | in progress | 16 |
|
||
| 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 |
|
||
| M4 | Files: STEP import (done: all 29 Fusion STEP files — [docs/step-import.md](docs/step-import.md)), 3MF export and 3MF/STL import as mesh bodies (done), DXF sketches, OBJ import | in progress | 6 |
|
||
| M5 | Persistent naming of faces and edges | planned | 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), live previews, measure tool, section view, drag-solve | in progress | 16 |
|
||
| M7 | Sweep, loft, rib, web, emboss, thread, coil, pipe | planned | 24 |
|
||
| M8 | Surface workspace | planned | 30 |
|
||
| M9 | Assemblies and joints | planned | 40 |
|
||
| M10 | Sheet metal | planned | 30 |
|
||
| M11 | 2D drawings | planned | 30 |
|
||
| M12 | Release: installers, signing, docs, performance | planned | 16 |
|
||
|
||
## Known limitations
|
||
|
||
- Fillets and chamfers: straight convex edges between planar faces with perpendicular planar end
|
||
faces; two blended edges may not share a corner yet.
|
||
- Booleans of curved bodies with coincident faces can fail (planar ones have an exact fallback);
|
||
fully internal voids are not supported. Spheres are built from six pole-free patches so they
|
||
combine reliably.
|
||
- Mass properties come from fine tessellation (curved faces within ~1e-4 relative).
|
||
- STEP import 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 (the tree is kept for M9).
|
||
- No persistent naming (fillet edges are re-found by position).
|
||
- Shell and draft work on convex bodies with planar faces; loft is ruled (no tangency end conditions).
|
||
- Dialogs have no live preview of the result yet.
|
||
|
||
## Kernel
|
||
|
||
truck (Apache-2.0) behind our own `kernel` crate, with our own blend operation and boolean
|
||
retry/validation; see `plan/adr/0001-geometry-kernel.md` (local) — summary in README.
