Properties

Select an object

Objects: 0 Selected: None

⬆ Extrude

Push a sketch profile upward along its normal to create a 3D solid.

Distance (mm)

Negative values extrude in opposite direction

⬇ Cut

Subtracts the sketch profile shape from an existing solid body below.

Cut Depth (mm)

◠ Fillet

Rounds the edges of the selected body with a smooth radius.

Radius (mm)

Larger radius = more rounded

◿ Chamfer

Bevels the edges of the selected body with a flat cut.

Distance (mm)

Distance from the edge to apply the bevel

Sketch Dimension

🔄 Revolve

Spins a sketch profile around an axis to create a solid of revolution (like a vase or wheel).

Axis Source

⊕ Centerline detected — will revolve around the drawn axis line.

World Axis

Angle (degrees)

Use 360° for full revolution, or less for partial arcs

Smoothness (segments)

Higher = smoother but slower (8-64 typical)

↗ Sweep

Sweeps a sketch profile along its normal direction with optional twist, like pulling taffy.

Sweep Distance (mm)

Negative values sweep in opposite direction

Twist Angle (degrees)

0° = straight extrude, 90° = quarter turn, 360° = full helix

Steps / Segments

More steps = smoother twist (needed for twist > 0)

◇ Loft

Creates a tapered solid by scaling the sketch profile from start to end (like a pyramid or funnel).

Depth (mm)

End Scale Factor

0.01 = near-point (pyramid), 0.5 = half-size, 1.0 = same size (cylinder), 2.0 = flared

▢ Shell

Hollows out a solid body, leaving only thin walls — like making a box into a container.

Wall Thickness (mm)

Must be less than half the smallest dimension of the object

⬌ Mirror

Creates a mirrored copy of the selected body across the chosen reference plane.

Mirror Plane

Merge with original (boolean union into one body)

⫼ Linear Pattern

Repeats the selected body in a straight line along the chosen direction.

Number of Copies

Includes the original (2 = one copy, max 50)

Spacing (mm)

Distance between each copy center-to-center

Direction

⟳ Circular Pattern

Repeats the selected body in a circle around the chosen axis through the world origin.

Number of Copies

Evenly spaced around the circle (includes original)

Total Angle (degrees)

360° = full circle, 180° = half circle

Rotation Axis

⊕ Boolean Operation

Combines two bodies using CSG (Constructive Solid Geometry). Select exactly 2 bodies using Shift+Click before opening.

Operation Type

Union: Merges both bodies into a single combined solid.
