Inserting some bolts and mates into a series of holes in a curve pattern.

I used a CrvPattern to generate a series of holes followingaspline on a plate and now I want to insert a copy of a boltwithit's mates into the series of holes but I get the error"CannotPattern: Could not find proper pattern location". I'm using2007 SP2 and the sketch spline is fully defined. Any ideas?


edit:  I've attached the file to look at. Basically Iwant to be able to control the number of holes andthe spacingalong the spline and be able to change them at will. Also isit possible on a 3D surface so for example if I wantto insert arow of rivets down the side of an aircraft fuselage?

I seem to keep getting errors so I'm posting the file here:
