Flat pattern

[Ariabod]

Hi,
The thing is that, I have mirrored some sheet metal components in an assembly and added a few extra holes to one of the mirrored (copy) parts. The problem is when I open the mirrored part file (.ipt) hit the "Flat pattern" icon and nothing happens. Can any one suggest what should be as other wise I have to model everything from scratch.
Thanks in advance.

See whether the thickness of the material setting is correct. Materials and Colors don't go along together when mirroring.
