The 3D editor
A scene of simple bodies and exact parts: draw, build, join, measure, cut with a plane and assemble mechanisms.
Scene and view
Key 3 or the Create button adds a scene. The view is set on the right toolbar: projection, grid, ground colour (a light grid by default, like Fusion 360) and the “Do not go below ground” option. The grid step follows the zoom: near a tiny part the cell gets smaller.
Creating bodies
- Primitives
- cube, sphere, cylinder, cone, capsule, torus, plate, propeller.
- Revolved and extruded shapes
- from a contour drawn in a sketch on a plane; a sketch can be built from a drawing too.
- People for scale
- man, woman, child in the Create menu, sized in metres.
- AI model
- a text description becomes editable parts (see AI helpers).
Modifying
- Push/Pull
- pick a face and give a distance: the body extends or is cut in.
- Follow Me (sweep)
- a profile — circle, rectangle or contour — is swept along a chosen line.
- Fillet, chamfer, shell, arrays
- the Modify menu for exact parts.
- Point to point
- pick a point on one body and a point on another — the first snaps to the second.
- Align, size, scale
- quick buttons on the panel beside the body.
Measuring
The ruler shows the distance and tells how it lies: “along the red/green/blue axis”, “at the midpoint”, “parallel to the edge”. Dimensions can be pinned to the scene.
Keeping a scene tidy
- Components
- a component copy repeats a shape: editing one copy changes all; “Make unique” detaches a copy.
- Groups and tags
- tag, for example, all furniture: hide it with one click or colour it by tag.
- Scenes (views)
- save a camera angle and return to it from the view menu.
- Section plane
- an axis cut with a filled section; saved as a view.
Physics and mechanisms
Bodies can be dynamic or static, joined with joints and mechanisms and simulated. Material (metalness, roughness, opacity, texture) and aerodynamics are on the Physics tab. By default a body looks like grey satin with soft reflections; set any colour you like.
