Open the Transform1.CATPart document.

  1. Click the Affinity icon .

The Affinity Definition dialog box appears.

  1. Select the element to be transformed by affinity.

  2. Specify the characteristics of the axis system to be used for the affinity operation:

the origin
the xy plane
the x-axis.

  1. Specify the affinity ratios by entering the desired X, Y, Z values.

The figure below illustrates the resulting affinity
with ratios X = 2, Y =1 and Z=1.

The figure below illustrates the resulting affinity
with ratios X = 2, Y =1 and Z=2.

The figure below illustrates the resulting affinity
with ratios X = 2, Y =2.5 and Z=2

  1. Click OK to create the affinity element.

The element (identified as Affinity.xxx) is added to the specification tree.

The original element  is unchanged.
You can perform an affinity on several elements at a time. In this case, refer to Editing a List of Elements to find out how to display and manage the list of selected elements.
