Hi
I have 2 circles: one inside another. I need to divide the area between circles, along radius lines, into 60 equal parts.
How can I achieve this? Please advice.
Thanks
Pankaj
Dividing circles into equal parts?

Some... ring, right?
>[...]along radius lines, into 60 equal parts.
In 6° steps, right?

Ye, I'm sorry. The server's HDD went up in smoke. The issues is addressed as we speak and it should work again in an hour or so.

Exactly, how do you do that?
Re: Dividing circles into equal parts?
1. Create a ring. Either by using difference (path->difference) with two circles or by converting the stroke of a circle to path (path->stroke to path).
2. Draw a straight horizontal or vertical line (use the bezier tool and hold ctrl) on top which is longer than the diameter of the circle. (And either center it through the align dialog or use the grid to place it accurately.)
3. Select the line and duplicate it (ctrl+d).
4. Rotate it by 6° (object->transform).
5. Select both lines and combine em (ctrl+k).
6. Switch to the node tool and select two nodes at one end, then hit the "join selected endnodes with a new segment" button.
7. Repeat the same with the other side.
Now you should have a ring and some kind of hourglass shape.
8. Ensure that the "hourglass" is below the ring.
9. Select both, then Path->Intersection.
10. Path->Break apart (ctrl+shift+k).
11. Group (ctrl+g).
12. Edit->Clones->Create Tiled Clones...
[Symmetry]
P1: Simple Translation
[x]Rows, Columns: 1 x 30
[Shift]
Shift X, Per Column: -100%
[Rotation]
Angle, Per Column: 6°
create.
13. Del (the original should be still selected at this point)... if the clones disappear go to File->Inkscape Preferences... Clones... When the original is deleted, its clones are: [x] unlinked.
14. Select all (ctrl+a).
15. Ungroup (ctrl+shift+g).
The statusbar should read: 60 objects of type Path in layer <whatever>.
16. In order to check that everything is alright use: Effects->Color->Randomize to colorize everything in some random colors.

Ye, it's indeed a bit long winded (easy to do tho). That's why I asked first if this is really what you're looking for.
