How do I create links in a file like a table of contents to different sections in a .pdf document?

Question

I'm trying to take multiple files and create one large (165 page) document but would like to create links to the different "chapters" within the document.

LH,
You may (you can see Groups in the Layers palette with the layer expanded):
1) Ctrl/Cmd+A to select everything and Ctrl/Cmd+Shift+G to Ungroup ;
2) ShiftClick the circle to deselect it; if it is still a Group (all of its own), Ungroup again;
3) With the Centre Reference Point ticked in the Transform palette multiply the W or H value by 1.1 (just add *1.1 in the box) and Ctrl/CmdEnter to keep proportions (this is to make sure that they are long enough);
4) Ctrl/Cmd+A to select everything again and Pathfinder>Divide (this will make pie pieces);
5) Drag over the centre with the Direct Selection Tool and press Delete (this will rid you of the inner parts of the pie pieces so you just have the outer rim in pieces).
This should give you the 30 independent curved lines forming the circle, two of them with an extra (original) Anchor Point.
