Robots, lasers and a template library
- Robot export: URDF, MJCF, SDF and a ROS 2 package straight from an assembly, checked before it is written.
- Laser and CNC: a thickness parameter, finger joints, box and living hinge generators, and kerf added at export.
- Twenty parametric templates, from a finger-joint box to an SO-101 gripper finger.
- The AI chat looks at photos, screenshots and the marks you draw on the model.
- Sketch patterns driven by parameters, thousands of copies at a time.
- Accounts and AI plans, in an invite-only beta.
Curves, text and things to trace
- Control point splines, blend curves and a curvature comb.
- Sketch text in any outline font, ready to extrude.
- Insert DXF, SVG, meshes and pictures to trace over.
- Ribs, webs, sweeps along a guide rail and lofts along a centreline.
- Save any body as a mesh.
- A cycloidal gearbox that builds itself, one step at a time.
Rounds of every kind
- Variable-radius fillets, with radius points along the edge.
- Chord-length and curvature-continuous fillets, full rounds and rule fillets.
- Setback corners for fillets; mitre and blend corners for chamfers.
- Patterns along a path, and zebra stripes to check a surface.
- A new name and a mark of its own: ProtoJoint.
- Icons on every tool, and every message in English and Chinese.
Assemblies that move
- Sub-assemblies, joint origins, and pin-slot and ball joints.
- Rigid groups, motion axes, and positions you can capture and go back to.
- Interference checks, section views and physical materials.
- Coil, thread, pipe, draft and scale, and boxes, cylinders, spheres and tori.
- Split a body with a sketch curve.
Familiar from the first click
- The keys, the marking menu and the S toolbox you already know.
- Parameters and expressions in every number field.
- Press Pull, Offset Face and Delete Face.
- Joints that snap, drive and animate, and motion links between them.
- Window and crossing selection, and a sketch saved as DXF.
Bring your parts
- Open .sldprt and .sldasm files and Parasolid, with their materials.
- Mass, volume and centre of mass from the exact solids.
- Designs in millimetres, centimetres, metres or inches.
- Slots, tangent arcs, and patterns in sketches and on solids.
- A view cube with 26 views.
First sheet
- Sketches with constraints and dimensions.
- Extrude, revolve, sweep, loft, hole, fillet, chamfer and shell.
- A timeline you can roll back and edit.
- Components and assemblies.
- Aluminium extrusion frames, with a beam check.
- Measure.
