Subtract and Replace
Subtract and Replace performs a boolean subtraction but keeps both resulting parts – the base with the cutout, and the piece that was cut away. This is useful for creating multi-part designs or color-separated objects.
How to Use
- Select two or more overlapping objects
- Click the Subtract and Replace button in the toolbar
- In the Properties panel, use Part(s) to Subtract and Replace to select the cutting objects
- The result contains both the subtracted base and the intersection piece as separate child objects
Parameters
- Part(s) to Subtract and Replace - Select which child objects act as the cutting shapes
When to Use This
- Multi-color designs - Split an object at color boundaries so each part can have a different color or material
- Assembly design - Create interlocking parts that fit together precisely
- Inlay work - Cut a shape from a base and keep the cutout as a separate insertable piece
Tips
- Unlike regular Subtract, this operation creates both the subtraction result and the intersection result as children
- Both resulting parts fit together perfectly since they were cut from the same boolean operation
- You can assign different colors to each resulting part for multi-material designs
