Booleans

Boolean operations involve the combination of 3D geometry. These operations include the following commands:

• Boolean union
• Boolean difference
• Boolean intersection

Boolean union

The BooleanUnion command trims the shared areas of selected surfaces or polysurfaces and creates a single polysurface from the unshared areas.

Steps:

1. Select the objects and press Enter. The objects combine into one polysurface.

Planar boolean operations combine 3D geometry.

• Boolean union
• Boolean difference
• Boolean intersection

Boolean difference

The BooleanDifference command trims the shared areas of selected polysurfaces or surfaces with another set of polysurfaces or surfaces.

Steps:

1. Select surfaces or polysurfaces to subtract from, and press Enter.
2. Select surfaces or polysurfaces to subtract with, and press Enter.

Note

• RhinoLands is a surface modeler. It's not possible to subtract a sphere inside another sphere to create a tennis ball-like object that has a solid wall enclosing a void.

Boolean intersection

The BooleanIntersection command trims the unshared areas of selected polysurfaces or surfaces.

Steps:

1. Select the first set of objects or a set of intersecting objects and press Enter.
2. If a first set of objects was selected, select the second set of objects and press Enter.

Command-line options

DeleteInput
Deletes (Yes) or keeps (No) the input object.

DeleteCutters
When DeleteInput=Yes, deletes the object used to subtract the other object.
