Subtract

Use Subtract to remove one or more tool bodies from target bodies, creating cavities, cutaways, pockets, and negative-space features. Subtract is the primary boolean operation for body-against-body material removal in complex assemblies.

Material removal.

Options

Target Solids

The bodies you want to keep. Material will be removed from these, but they'll stay in your model.

Tool Bodies

The bodies that define what gets cut away. These tools get deleted after the subtraction (they're consumed by the operation).

Important: Tool bodies must overlap with at least one target body. If they don't overlap, nothing happens.

Design Applications

Material Removal

Create complex internal cavities by subtracting shaped volumes from solid parts:

• Fluid passages in manifolds
• Weight-reduction pockets
• Assembly clearance volumes
• Mold core cavities

Multi-Body Workflows

Manage complex assemblies by maintaining separate bodies and using subtract to create proper interference-free fits:

• Bearing pocket clearances
• Shaft passages through housings
• Tool access volumes
