Scale by Bounding Box
This type of scaling is similar to the Scale command, however it allows manually scaling a piece or an internal contour. In order to scale several pieces, use the Scale command.
This command enlarges or reduces the actual piece size in the X and Y direction by a specified percentage. The Scale command is mainly used when working with materials that have a shrink or stretch factor. This command is also used when digitizing a miniature pattern from another source (i.e. a magazine or book), and wanting to scale it back to its actual size.

Note: If the piece is graded first and then scaled, the graded sizes are scaled along with the base size.
