Modifiers

Modifiers compose primitives into complete shapes. Boolean, mirror, array, twist — every one of them runs on the SDF directly, so the result is always a single, watertight surface. No mesh repair, no double-sided faces, no booleans that fall apart at zoom.

Where modifiers live

Open the Chisel section of the Object Properties panel and use the toolbar at the top of the modifier list to add, reorder, and remove modifiers. The pie menu (Q) also exposes the most common operations: boolean Difference / Union / Intersect, mirror, and quick adjustments.

Each modifier collapses into a header showing its name and active state. Click the chevron to expand its options. New modifiers expand by default — toggle that in the addon preferences if you’d rather they stay collapsed.

Categories

• Boolean — Difference, Union, Intersect, Slice. With smooth blending.
• Mirror — Reflect across one or more axes with optional smooth seam.
• Array — Linear and circular repetition.
• Solidify — Hollow into a shell of given thickness.
• Emboss & Engrave — Push a target shape outward (Emboss) or inward (Engrave).
• Twist & Bend — Deform along an axis.

Modifier UI tips

• Toolbar buttons add, remove, and reorder without leaving the panel.
• Header chevron expands or collapses each modifier’s options. New modifiers expand by default — change in Preferences.
• Quick boolean hotkeys (Alt + NumPad −/+/⁄) bypass the panel entirely: select operands, make destination active, tap the key.
• Adjust modal — B opens Adjust Rounding on a primitive; Ctrl+B opens it on the active boolean modifier. While active, keys 1–5 switch profiles instantly: 1 Round, 2 Sharp, 3 Soft, 4 Tight, 5 Chamfer; S toggles between the radius and the Chamfer Smooth value.
