Resize objects by the scale given in the source / argument box. A parameter value of 0.5 resizes objects to half their size. A parameter value of 2 resizes objects to twice their size. The Scale Horizontally and Scale Vertically operators resize objects by the scale given in the source / argument box only in their horizontal (East / West) or vertical (North / South) extent.
It is strongly recommended that drawings be projected before using these operators to provide maximum accuracy in scaling.
Scale Example
We will resize Germany within a drawing of Europe. The drawing has been projected into Orthographic projection.

We first select the area representing Germany. Next, load the Transform toolbar with
[selection] Scale 0.5
and press Apply. This is a command to resize Germany to half the former size.
Scale Horizontally Example
We will now resize Germany only in its horizontal extent.

We first select the area representing Germany. Next, load the Transform toolbar with
[selection] Scale Horizontally 0.5
and press Apply. This is a command to resize Germany to half the former size in the horizontal (East / West) direction. All vertical extents will remain the same.
Scale Vertically Example
We will now resize Germany only in its vertical extent.

We first select the area representing Germany. Next, load the Transform toolbar with
[selection] Scale Vertically 0.5
and press Apply. This is a command to resize Germany to half the former size in the vertical (East / West) direction. All horizontal extents will remain the same.
These commands are most frequently used in CAD-style editing of non-geographic data. They are shown here in a geographic setting to make clear their effect.
Tech Tip
Many transforms automatically run a Normalize Topology transform before running to eliminate common errors that may affect correct operation. The Scale transform operators do not normalize target objects before running.
