Hi. I am totally new to inkscape and I'm trying to make an indexing tool for my woodturning lathe. I need to start by creating round graph paper from which I can then make symmetrical designs by coloring in some of the spaces. Can someone help me? I have started with a round shape but can't seem to figure out how to add the graph. thanks for any help!

Maybe you have seen:

Menu: Extensions>Render>Grids>Polar Grid

Thank you very much. That's exactly what I'm looking for.
