It creates copies of the model along one or more chosen axes, according to a specified factor:
- either the whole model if nothing is selected
- or the selected voxels
If no axis is specified, transformation applies to all of them. Factor must be a rational number; negative values behaves like a mirror.
The center of the model after transformation is located at the geometric center of the voxels concerned by the transformation.
If the factor enlarges the model bigger than the current object size, the limits are modified accordingly, within a
256 voxels cap for each axis.
