Bisect

Cut selected objects by drawing a line in the viewport.

Bisect

Overview

Bisect mode allows you to split geometry by drawing a cutting line directly in the viewport. This is useful for dividing objects along arbitrary planes.

Basic Usage

  1. Select objects to bisect
  2. Activate Block tool in Edit mode
  3. Click and drag to draw the cutting line
  4. Release to execute the cut

Operation Notes

  • Draw line from outside the selection
  • Cutting plane is perpendicular to viewport
  • Works on all selected objects simultaneously

Operation Behavior

The bisect operation creates a cutting plane based on the drawn line:

  • Plane is perpendicular to the viewport
  • Direction determined by line draw direction
  • Affects all selected objects simultaneously
  • Creates clean cuts through geometry

Parameters

Location

  • Type: Vector (X, Y, Z)
  • Description: The center point of the cutting plane
  • Default: Calculated from drawn line midpoint

Normal

  • Type: Vector (X, Y, Z)
  • Description: Direction the cutting plane faces
  • Default: Perpendicular to drawn line and viewport

Mode

  • Type: Enum
  • Options:
    • CUT: Remove geometry on one side (default)
    • SPLIT: Separate geometry without removing
  • Default: CUT

Flip

  • Type: Boolean
  • Description: Reverse which side is removed in CUT mode
  • Default: False
  • Effect: Inverts the cutting direction

Tips

  • To start use it outside of selection with custom plane disabled
  • Bisect works on all selected objects simultaneously
  • The cutting plane is perpendicular to the viewport
