What is 3D array command in AutoCAD?
3DARRAY maintains legacy behavior. For 3D rectangular arrays, in addition to columns and rows, you also specify the number of levels in the Z direction. For 3D polar arrays, you specify the axis of rotation with any two points in space. The entire selection set is treated as a single element in the array.29 mar. 2020

When using 3D array which axis are the rows on?
The rows are indicated as the “axis 0”, while the columns are the “axis 1”. The number of the axis goes up accordingly with the number of the dimensions: in 3-D arrays, of which you have also seen an example in the previous code chunk, you’ll have an additional “axis 2”.
