### 9.4.5. Transformation: Scale

The `Scale` method is used to scale an assembly by a scale factor.

#### 9.4.5.1. Method: Uniform

The `Uniform` option uses the same scale factor for all coordinate directions, therefore scaling the size of the assembly while maintaining the same aspect ratio. Specify the scale factor by entering a value for Uniform Scale (which must be greater than zero).

#### 9.4.5.2. Method: Non Uniform

The `Non Uniform` option scales the assembly independently in each coordinate direction.

Enter scale factors Sx, Sy, and Sz to scale the X, Y, and Z coordinates of the assembly, respectively.

#### 9.4.5.3. Scale Origin

Scaling is achieved by multiplying the location of each mesh node relative to the Scale Origin by the scaling factor.

Enter the Scale Origin as a Cartesian coordinate (for example, `[0 0 0]`), or use Picking mode by clicking any Cartesian coordinate box then picking a point from the viewer. The working units are assumed to apply to the point coordinates. When you are in Picking mode, the Cartesian coordinate boxes turn yellow. To manipulate the object in the viewer while in this state you have to click the viewer icons (rotate, pan, zoom) in the toolbar. You can turn off Picking mode by changing the keyboard focus (by clicking on another field, for example).

#### 9.4.5.4. Apply Scale To

This setting controls whether the transformation is applied to the original mesh or to a copy of the mesh. If you have set up physics locations on the original mesh, such locations are retained after the transformation.

The following options are available:

`Original (No Copy)`

  Transforms the original mesh without making a copy.

`Copy (Keep Original)`

  Copies the original mesh before applying the transformation. In this case, the original mesh remains in its current location.
