BlockoutBoolean

Remarks

Non-destructive first, which is the whole point of the phase. A subtract makes a new entity whose geometry is derived from its operands; the operands become its hidden children and stay editable. "The doorway should be twenty centimetres wider" is then dragging a box that is still there rather than rebuilding a wall.

⚠ The cuts are destructive and the booleans are not, and that asymmetry is the honest one. A plane cut's operand is a plane, which is not an entity and has nowhere to survive as one — so keeping it live would mean inventing a second kind of operand with its own gizmo, its own row in the outliner and its own file format. A trim's operand is an entity, and it is still destructive because the thing a trim is for is throwing the cutter away afterwards.

Methods (7)

• public static Entity Combine(SceneDocument document, BooleanOperation operation, string? name = null)

  Combines the selected entities into one derived result, undoably.

• public static Entity Union(SceneDocument document)

  Everything in either of the selected solids.

• public static Entity Subtract(SceneDocument document)

  The first selected solid, less the rest.

• public static Entity Intersect(SceneDocument document)

  Only what all the selected solids share.

• public static bool Collapse(SceneDocument document, Entity entity = default(Entity))

  Collapses a derived result into a plain mesh and deletes its operands, undoably.

• public static int PlaneCut(SceneDocument document, Plane plane, bool keepFront = false, bool cap = true)

  Cuts the selected solids with a plane, undoably.

• public static bool Trim(SceneDocument document, bool keep = false)

  Cuts the first selected solid by the second's surface and deletes the cutter, undoably.
