Scale (model) (interface)/0.99.5a

Scale is a retractable text area from Model editor's edit panel. Not to be confused with scale (render).

Changes the size of the model along one or more chosen axes, according to a specified factor: If no axis is specified, transformation applies to all of them. Factor must be a positive rational number. The center of the transformation is located at the geometric center of the voxels concerned by the transformation.
 * either the whole model if nothing is selected
 * or the selected voxels

If the scale factor enlarges the model bigger than the current object size, the limits are modified accordingly, within a  voxels cap for each axis.
