Precision geometry for the agentic era.
Locus builds tools for turning ideas into physical designs. Start with Locus Studio: sketch custom parts, shape smooth surfaces, and explore assemblies in your browser. Discover the geometry, lattice, and AI tools behind it.
Studio is in development. Tell us what you want to make.
From a profile to a part you can revise
A modeling workflow for custom knobs, housings, and other product concepts. These steps describe Studio; the interactive scenes above are geometry previews.
- 01
Sketch the profile
Draw a profile or import supported SVG and DXF outlines, then extrude or revolve it.
- 02
Shape and revise
Edit dimensions and sculpt surface controls as you explore the part's form.
- 03
Export and check
Export supported geometry to STEP or mesh formats and check the result in your downstream workflow.
Explore the Locus tools
Start with browser CAD, or explore the geometry engine, agent interface, and lattice tools being developed alongside it.
Locus Studio
Browser-based parametric 3D CAD modeler. Draw 2D sketches, sculpt true cubic NURBS control nets, assemble multi-part mechanisms, and export supported models to STEP.
- Interactive millimeter sketch workplane
- 3D control net sculpt with Gaussian falloff
- Multi-body assembly clearance detection
Locus Core
The high-performance geometric computation engine. AST-sandboxed math evaluation, bounded multiprocessing worker pools, and topological boundary stitching.
- Bounded multiprocessing worker pool
- AST-sandboxed expression evaluation
- SHA-256 LRU geometry caching
Locus Agent & MCP
Model Context Protocol interface enabling autonomous AI models to design, fillet, assemble, and validate real physical parts with zero manual clicks.
- Standard MCP protocol tool definitions
- Automated physical mass & volume audit
- JSON-schema bounded validation
Locus Metamaterials
Implicit Triply Periodic Minimal Surface (TPMS) engine. Explore Gyroid, Schwarz-D, and Neovius lattice geometries and their parameters.
- Parameterized lattice fields
- Implicit lattice design exploration
- Watertight boundary cap integration
Foundations of Computational CAD
How Locus solves fundamental geometric and systems challenges in next-generation mechanical engineering.
Dual-Kernel Client/Server Decoupling
The browser displays interactive geometry while the backend evaluates modeling operations. Response times depend on the operation, model size, hardware, and workload.
Topological Watertightness & Signed Volume
Watertightness, consistent winding, positive signed volume, and nondegenerate faces guide solid validation. Acceptance depends on the geometry path and parameter range; these checks are not a universal self-intersection certificate.
Exact Knot-Inserted Rational NURBS
True cubic degree [3, 3] NURBS surfaces with outer B-spline hull control nets. Preserves rational weights, closed-seam polar welding, and native STEP B_SPLINE_SURFACE_WITH_KNOTS export without polygon facet degradation.
Agentic Hardware Synthesis via MCP
Autonomous AI agents execute precise parametric CAD design workflows through Model Context Protocol (MCP). Agents generate 2D sketches, apply fillets, verify multi-body clearances, and export validated ISO-10303 STEP solids.
One platform, different ways to design
Explore the tools that fit your work. Studio and the wider platform are in development; early access is offered individually.
