Boolean Operations

Boolean operations combine two or more 3D objects into a single solid. Union merges them together. Cut subtracts one from another. Intersect keeps only the volume where they overlap. Split divides one shape by another into two pieces. Start with simple shapes — primitives, extrusions, revolves — and combine them to build geometry that would be difficult to model any other way.

The Parts Tree shows the result’s internal structure so you can see how your shapes relate. Deep Edit lets you reach inside a boolean result and modify its sub-components directly in the 3D viewport.

The Result Part

Union, Cut, and Intersect create a new part rather than modifying the first selected object. The result sits where the first object was. It shows in the parts tree under its own name: Union, Cut, or Intersect. Both source objects are hidden, not deleted. Linked clones of the source objects are not affected. Use the Parts Tree to inspect the structure of the result, and Deep Edit to reach inside and adjust the sub-components.

• Union — merge shapes into one solid, with Blend and Meld for the seam
• Cut — subtract one shape from another
• Intersect — keep only the volume two shapes share
• Split — divide one shape by another into its outside and inside pieces
• The Parts Tree — read the structure of a combined object
• Deep Edit — edit sub-components inside a boolean result

• Union Merge two or more shapes into a single solid, with a sharp, blended or melded seam.
• Cut Subtract one shape from another, removing the volume where they overlap.
• Intersect Keep only the volume shared by two shapes.
• Split Divide one shape by another into two complementary pieces — the part outside the second shape and the part inside it.
• The Parts Tree A hierarchical view of all objects in the model, showing boolean relationships and structure.
• Deep Edit Drill into a boolean or packed entity to select and edit individual sub-components directly in the viewport.
