This is basic triangulation. Easy to do when you know how but some people struggle with it.
Start by drawing a side view and plan. Divide your plan into 12 segments and plot them onto your side view. Use each of these to mark out your pattern.
Your pattern will be 942.6 mm long and again marked into 12. I cant really go into much more detail here. It is difficult enough to show someone in person!
If you know what you doing it should take about an hour to mark out by hand and look like youv'e drawn a simple bump on large graph paper. (Or a dip depending on whether you want the join on the throat or back of the bend segment.)
Point 0 (and 12) will be the lowest, point 6 the highest and you will know you've done it right if points 2,3 and 4(also 10,9 and 8 respectively) join in a staight line.

I would invest in a geometry of sheet metal work book. I did my city and guilds in sheet metal work and i still refer to the copy that I have, follow this link www.studentbookworld.com/BookDetail/0582009618.html
mine was a very old Colin's edition that 30 years old but still very valuable reference.
