Modificador Repetir#

The Array modifier creates an array of copies of the base object, with each copy being offset from the previous one in any of a number of possible ways. Vertices in adjacent copies can be merged if they are nearby, allowing smooth Subdivision Surface frameworks to be generated.

This modifier can be useful when combined with tileable meshes for quickly developing large scenes. It is also useful for creating complex repetitive shapes.

Multiple Array modifiers may be active for an object at the same time (e.g. to create complex three-dimensional constructs).



The Array modifier.#

Fit Type

Controls how the length of the array is determined. There are three choices, activating respectively the display of the Curve, Length or Count settings explained below:

Fit Curve

Generates enough copies to fit within the length of the curve object specified in Curve.

Fit Length

Generates enough copies to fit within the fixed length given by Length.

Fixed Count

Generates the number of copies specified in Count.


  • Both Fit Curve and Fit Length use the local coordinate system size of the base object, which means that scaling the base object in Object Mode will not change the number of copies generated by the modifier.

  • Ajustar curva utiliza la longitud del sistema de coordenadas local de la curva, lo que significa que escalar la curva en el Modo Objeto no cambiará el número de copias generadas por el modificador.

  • Applying the scale can be useful for both.

Relative Offset#

Factor X/Y/Z

Adds a translation equal to the object’s bounding box size along each axis, multiplied by a scaling factor, to the offset. X, Y and Z scaling factors can be specified.


Relative offset (0.5, 1.0 and 1.5) examples.#

Constant Offset#

Distance X/Y/Z

Adds a constant translation component to the duplicate object’s offset. X, Y and Z constant components can be specified.

Object Offset#

Adds a transformation taken from an object (relative to the current object) to the offset. It is good practice to use an empty object centered or near to the initial object. E.g. by rotating this empty a circle or helix of objects can be created.


Object offset example.#


If enabled, vertices in each copy will be merged with vertices in the next copy that are within the given Distance.

First and Last Copies

If enabled and Merge is enabled, vertices in the first copy will be merged with vertices in the last copy, again if they are within Distance range. This is useful for circular objects.

First and Last Copies merge example.#

Subdivision discontinuity caused by not merging vertices between first and last copies (First and Last Copies off).#


Subdivision discontinuity eliminated by merging vertices between first and last copies (First and Last Copies on).#


Controls the merge distance for Merge and First and Last Copies.


Offset U/V

Shifts UVs of each new duplicate by a settable amount.


Cap Start, End

This allows either endpoints of the array to have a different mesh subsisted.

For the start: as if it was in position -1, i.e. one «array step» before the first «regular» array copy. For the end: as if it was in position n + 1, i.e. one «array step» after the last «regular» array copy.

When Merge is activated, the cap vertices within the Distance threshold will be merged.


The start/end cap objects currently do not support the First and Last Copies option.


Offset Calculation#

The transformation applied from one copy to the next is calculated as the sum of the three different components (Relative, Constant and Object), each of which can be enabled/disabled independently of the others. This allows, for example, a relative offset of (1.0, 0.0, 0.0) and a constant offset of (0.1, 0.0, 0.0), giving an array of objects neatly spaced along the X axis with a constant 0.1 unit between them, whatever the original object’s size.
