user: Describe Options from the Blender manual or Python API, including usage steps and snippets.

assistant: Shape
:   The method used for arranging the duplicates.

    Line:
    :   Arranges copies along a straight line.

    Circle:
    :   Arranges copies around a circle.

    Curve:
    :   Arranges copies along a curve input.

    Transform:
    :   Uses a transform offset or object transform to position each copy.

Offset Method Line
:   Determines how copies are spaced along a line.

    Relative:
    :   Offsets each copy relative to the bounding box size of the geometry.

    Offset:
    :   Offsets copies by a fixed world-space distance.

    Endpoint:
    :   Distributes copies evenly between start and end points.

Offset Line Relative
:   The amount to move each copy relative to its bounding box size when using *Relative* mode.

Count Method Circle Curve
:   Determines how the number of duplicates is defined.

    Count:
    :   Sets a fixed number of copies.

    Distance:
    :   Sets copies based on distance between them.

Count Circle Curve Count
:   The number of copies to generate.

Angular Distance Circle Distance
:   The angular distance between copies when using *Circle* shape.

Central Axis Circle
:   The axis used as the up direction for circular arrangements.

Circle Segment Circle
:   Determines whether the copies form a full circle or just a partial arc.

    Full:
    :   Copies are evenly spaced around a full 360° circle.

    Arc:
    :   Copies fan out along a circular arc.

Radius Circle
:   The radius of the circle along which the copies are distributed.

Sweep Angle Circle Arc
:   The total angle (in radians or degrees) spanned by the arc when *Circle Segment* is set to *Arc*.

Per Curve Curve
:   Specify the number of copies for each curve separately.

Curve Object Curve
:   Reference curve object for array.

Transform Reference Transform
:   Defines how the transform is applied for *Transform* shape.

    Input:
    :   Uses the transform specified directly in the node inputs.

    Object:
    :   Uses the transform of a specified object as the reference.

Translation Inputs Line Offset Endpoint
:   The positional offset applied to each copy.

Rotation Inputs Line
:   The rotation offset applied per copy.

Scale Inputs Line
:   The scale factor applied per copy.

Transform Object Transform Object
:   The object whose transform is used when *Transform Reference* is set to *Object*.

Relative Space Transform Object
:   Determines whether the transform is applied in object or world space.

Realize Instances
:   Converts the generated instances into real geometry.
    This must be enabled for certain operations such as merging or boolean operations.

### Align Rotation Circle Curve

Forward Axis
:   Axis that defines the facing direction of each instance along the circle.

Up Axis
:   Axis used as the vertical reference for instance orientation.

### Randomize

Offset
:   Maximum random translation offset for each axis, defining the variation in instance position.

Rotation
:   Maximum random rotation for each axis, defining how much each instance can be rotated.

Scale Axes
:   Determines how scaling randomization is applied.

    Uniform:
    :   Applies a single random scale factor uniformly to all axes.

    Axes:
    :   Applies independent random scale factors per axis.

Scale
:   Maximum random scaling factor applied to each instance.

Flipping
:   Randomly mirrors instances along one or more axes.

Exclude First / Last
:   Excludes the first (original) or last copy from randomization effects.

Seed
:   Initializes the random number generator.
    Changing the seed produces a different random arrangement while preserving other settings.

### Merge

Merges overlapping points or vertices by distance.
Requires *Realize Instances* to be enabled.

Distance
:   The distance threshold within which points are merged.
