I et blikk

Temaet	SolidCraft	Frigjøring
Tillatelse	MIT eller Apache 2.0 (dual)	LGPL-2.0 eller senere (applikasjon)
Geometriske kjerner	Pure-Rust B-rep stack (SolidCore / prosjektkjernen arbeid)	OpenCASCADE teknologi (OCCT)
Ui modell	Enkel parametrisk redaktør + funksjon timeline	Workbench-basert (PartDesign, Sketcher, TechDraw, Path, FEM, ...)
Sketch begrensninger	Begrensede skisser på timeline	Sketcher Workbench (Mature Constraint Solver) er en
Maturitet	Tidlig; «brukbar for enkle deler» per prosjekt	Mature 1.x linje (1.1.4 vedlikehold fra 2026-09)
Tegninger / CAM / FEM	Ingen CAM/FEM i appen; tegninger i gang (ikke levert)	TechDraw, Path (CAM), fem arbeidsbenker
Native format	`.sc`(Eldre`.solidcraft`Fortsatt åpent	`.FCStd`
Utveksling	STEP, IGES, 3MF, STL og OBJ`.FCStd`/Rhino via cadmpeg	STEP, IGES, STL, SVG, DXF, OBJ, IFC, DAE og mer
Fusjon`.f3d`	Ingen dokumentert innfødt importør – bruk STEP	Ingen førsteparts Fusion native importør (bruk STEP/interchange)
Plattformer	Windows / macOS / Linux desktop + offisiell wasm web app	Windows / macOS / Linux skrivebord (primær)
Skriveren	JSON kommandoskripter, headless CLI, unit-aware parametere	Deep Python API, makroer, workbench addons
AI / MCP	Bygget inn`SolidCraft-cli mcp`	Fellesskap MCP broer (f.eks. FreeCAD-mcp); ikke kjerne

Kerneler og modelleringsstil

Who should pick which

Prefer SolidCraft when…

You want an agent-native CAD loop (MCP/CLI) without standing up a separate FreeCAD bridge.
Parts are relatively simple parametric solids / enclosures matching the project’s early scope.
You care about a browser app plus desktop, or dual MIT/Apache licensing for embedding experiments.

Prefer FreeCAD when…

You need TechDraw drawings, Path/CAM, FEM, or BIM-oriented workbenches today.
You already live in FreeCAD’s Python/macro/addon ecosystem.
You want a larger, longer-running open-source CAD community and training materials.

File formats and migration

Best shared solid format: STEP (both directions).
FreeCAD → SolidCraft: STEP, or .FCStd via cadmpeg on desktop, in the browser app and in the CLI (geometry import; history not preserved).
SolidCraft → FreeCAD: export STEP/IGES/mesh as needed, then continue in FreeCAD workbenches.
Fusjon.f3d: neither project documents a faithful native Fusion history importer; export STEP from Fusion first.

FAQ

Is SolidCraft a FreeCAD replacement?

Not today for most production workflows. FreeCAD (latest stable 1.1.x) is a mature, workbench-based suite with TechDraw, Path/CAM, FEM and a huge addon ecosystem. SolidCraft is early, focused on parametric solids, a single editor workflow, and first-class MCP/CLI automation.

Can SolidCraft open FreeCAD .FCStd files?

Yes for solids via the documented cadmpeg path (same family as STEP import) in the desktop app, browser app and CLI: you get geometry as an Import base feature, not FreeCAD’s full parametric history. Prefer STEP when you only need B-rep interchange.

Does FreeCAD have MCP like SolidCraft?

SolidCraft ships SolidCraft-cli mcp in-tree. FreeCAD MCP exists as community projects (for example neka-nat/FreeCAD-mcp) that typically require FreeCAD running with an addon or bridge—not a built-in stdio server in the core app.

Which is better for AI agents?

If you want a local, headless CAD command surface with one binary, SolidCraft’s MCP is designed for that. FreeCAD agents usually drive FreeCAD through community MCP bridges and Python. Pick based on whether you need FreeCAD’s workbenches or SolidCraft’s agent-native CLI.

What about drawings, CAM, and FEM?

FreeCAD includes TechDraw, Path (CAM), and FEM workbenches. SolidCraft’s public roadmap defers drawings, CAM/manufacture, and simulation.
