Rotate the Feature in the Pattern

Hi everyone,

I need to create a pattern base in a single feature.

I have this feature (just a shape to understand the rotation)

p

And I want to create this pattern

p d p

d p d

p d p

d p d

p d p

This mean that I need to rotate the part in each of the steps of the pattern in 2 directions.

Any one know how to do something like that!!!

I am making this in a sheet metal environment using SW 2009

Thanks
