How Can I Create This Hole Pattern in a Bent Part?

I have created a part using sheet metal that is formed around a radius (see images below).  I need to put a hole pattern in here (air vent), and have been using a flat face on one side of the part to reference my holes.  The workflow is as follows:

 

  • Create initial formed geometry
  • Unbend
  • Insert hole pattern (using fill pattern feature)
  • Unbend

 

Doing this doesn't work as the part fails when I try to unbend (apparently the split line I used to define the fill area, as well as the hole and pattern themselves (?) cause the unbend feature to fail.  How can I put this hole pattern in and still maintain the formed radius?
