Prior to NX8, Edge Blend and Chamfer features could not be instanced in a Pattern.
How to add an Edge Blend feature to the new Pattern feature.
Solution
1. Select 'Insert-->Associative Copy-->Pattern Feature'.
2. Select the Edge Blend or Chamfer feature to pattern.
3. Select the parent feature of the chosen Edge Blend or Chamfer feature.
For example, if the Chamfer belongs to the edge of a Hole, select the
parent Hole feature to also pattern.
4. Under the Pattern Method group, set 'Method = Variational'.
5. Set any other desired Pattern options.
6. OK the Pattern Feature dialog.
The Pattern Feature created will include the Edge Blend or Chamfer feature.
