Attached a piece of tape over the front spar bottom rivet line to the nose bend line and marked these lines on the tape. For the sake of creating my layout drawing this distance was measured on a flat surface at 130mm. Flipped skin and used the marked tape to transfer the 130mm dimension to the top. Marked a line for the front spar top rivet line that directly mirrors the bottom.
From the spar line I then mirrored the rib rivet locations with the end rivets being at 22mm and 262mm from the spar line. The specified pitch of 60mm for the remaining 3 rivets works out perfectly - 5 total over 240mm.
Note: This is how I actually made my measurements since my idea for a complete layout did not occur to me until after my skin was already bent. Were I do do this again the entire skin would be marked before bending as described in my 8/29/11 post.
