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).
- Tipo de encaixe
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:
- Encaixar em uma curva
- Generates enough copies to fit within the length of the curve object specified in Curve.
- Encaixar no comprimento
- Generates enough copies to fit within the fixed length given by Length.
- Contagem fixa
- 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 Array Modifier.
- Fit Length uses the local coordinate system length of the curve, which means that scaling the curve in Object Mode will not change the number of copies generated by the Array Modifier.
- Applying the scale with Ctrl-A can be useful for each one.
- Constant Offset, X, Y, Z
- Adds a constant translation component to the duplicate object’s offset. X, Y and Z constant components can be specified.
- Relative Offset, 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.
- Deslocamento por objeto
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.
- If enabled, vertices in each copy will be merged with vertices in the next copy that are within the given Distance.
- Primeiro e último
If enabled and Merge is enabled, vertices in the first copy will be merged with vertices in the last copy (this is useful for circular objects).
- Controls the merge distance for Merge.
- U Offset, V Offset
- Shifts UVs of each new duplicate by a settable amount.
Ponteiras das terminações¶
- Start Cap / End Cap
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, and the cap vertices are within the distance threshold, they will be merged.
The start/end cap objects currently do not support the First Last option.
Calculação dos deslocamentos¶
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.
