Scale on the Change toolbar reduces or enlarges selected elements by a scale factor that you define. The scale factor is the same along the x and y axes. Scalable elements include framed elements, such as text boxes. You cannot use Scale to scale or scale and copy elements in a drawing view because a scale factor has already been applied to the drawing view.
Relationships within the selection set are maintained if the relationships are still applicable after the elements have been scaled. If not, the relationships are deleted.
To define the new scale, you can click points on the drawing sheet or you can type a value in the Scale Factor box on the ribbon. You can also use the Step box on the ribbon to make the Scale Factor increase or decrease incrementally as you move the mouse.
