3DArray command copies 3D object as space array.

There are types of array: Rectangular array and Polar array.

2. Rectangular Array

• 3darray

Initializing… 3DARRAY loaded.
Select objects: Select object to copy as array.
Select objects: Select next object to copy as array or press ENTER

Specify the angle to fill (+=ccw, -=cw) <360>: Specify the angle to create the array.
Rotate arrayed objects? [Yes/No] <Y>: Y Rotate arrayed objects to center?.
Specify center point of array: Specify center point of array as the first point of rotation axis (1).
Specify second point on axis of rotation: Specify the second point of rotation axis (2).
