Mechanical design studio
Design it in parts.Prove it in motion.
For DIY builders, makers, woodworkers and metalworkers, students, and small fabrication shops. Real lumber sizes, real hardware and real hard stops, so the thing on screen is the thing you can cut, bolt and swing.

Sample assemblies
Start from a working assembly
Each one opens as a live document: parts on real stock sizes, joints with hard stops, fastener stacks, and a bill of materials that updates as you edit. Nothing is a screenshot.
Pivoting Lumber Joint
2x8 rail on a 4x6 post, hung on a 1 in through-bolt pivot
The connection every DIY build turns on. One bolt, two washers, a nut, and the choice between a clamped joint and a pivot. Press play and the rail sweeps 45 degrees either side of level, inside 60 degree hard stops.
Wheel and Axle
10 in wheel on a fixed 5/8 in shaft, spacers and nyloc retention
A driven rotational joint with no limits. Set the RPM, press play, and read angular velocity live while the shaft stays put.
Folding Workbench Concept
48 x 24 top on two folding leg frames, 1/2 in carriage bolt pivots
Rigid joints and pivots working together. Five parts per leg frame move as one member through an 85 degree fold.
Small Utility Cart Concept
36 x 20 deck, four 8 in wheels on fixed axles, tilting tow handle
Four independent wheel joints and a limited handle pivot on one frame. The scene tree earns its keep here.
Gate Hinge Concept
42 in braced gate on a 4x6 post, two strap hinges, 110 degree swing
A braced leaf on a single vertical hinge axis. Seven parts swing as one rigid sub-assembly.
Capability board
What ships today, and what is coming
One board, no asterisks. Anything marked live is running in the build you are looking at right now.
Included
ShippingRunning in this build, on every document you open.
- Kinematic solverLive
Positional constraint solve across joint chains, running now on every scene.
- Bill of materialsLive
Live part grouping, mass roll-up and CSV export from the current document.
- Cut listLive
Linear stock grouped by length, with a first-fit estimate of sticks required.
- Design CopilotBeta
Reads the live document and answers questions about the mechanism you built.
- Rigid-body dynamicsLive
Gravity, contacts, joint limits, motors on driven joints, and joint friction and damping, backed by Rapier.
- Structural analysisLive
Member sizing for rectangular and round stock, NDS dowel yield for bolts in timber, shank shear, deflection under service load.
- PDF plan exportLive
Dimensioned plan and elevations, an exploded view, cut list and BOM, printed or saved as PDF.
- Realistic materialsLive
Wood grain, knots and grade stamps, mill scale and plating on metal, lit in five looks from shop floor to daylight.
All of it runs on your machine. No account, no upload, no watermark.
Pro
Not in this buildInterference sweeps and the fabrication modules. Not enabled in this build.
- Swept interferencePro
Sweeps every joint through its full range and reports the first collision.
- Cut optimisationPro
True one dimensional nesting across stock lengths, kerf aware.
- CNC and DXF exportPro
Flat patterns and hole schedules out to DXF, STEP and G-code posts.
- Supplier pricingPro
Live regional pricing against the BOM, with substitutions that cost less.
Priced when it ships. Nothing here is billed today.
Studio
Not in this buildThe team and cloud layer, with everything in Pro included.
- Cloud projectsStudio
Documents that follow you between machines, with offline first sync.
- Version historyStudio
Named checkpoints, visual diffs between revisions, restore any point.
- Live collaborationStudio
Multiple cursors in one assembly, with comments pinned to parts and joints.
- Team workspaceStudio
Shared part libraries, house materials and per-shop fastener standards.
- Component marketplaceStudio
Manufacturer models with real part numbers, dropped straight into the BOM.
- AR previewStudio
Stand the assembly on the shop floor at full size before cutting anything.
For shops with more than one pair of hands on the same build.
Straight answer on the solver: this build runs two of them. Kinematic positions the assembly exactly through its joint chains, nothing has mass and nothing falls. Dynamics runs a real rigid-body simulation with gravity, contacts, motors on driven joints and Coulomb pin friction, and refuses ball joints rather than approximating them. Structural checks size a member against a load you state, and they are mechanics of materials, not a code check.
