Thanks Watkins, that gets me out of trouble.

Thanks Watkins, I´ll give it a try and get back to you.
Regards Dintel.

I am trying to make a curved staircase in sketchup 7.I make a circle of say 40 segments then use the offset tool to set the inner diamiter,select one of the circles by clicking on it with select, then click on divide by 14 which is the number of steps I want. When I hover over the line with the draw tool it only highlights the 40 segments of the circle and not the 14 division points I made. The divide works fine on straight lines but I just can´t get it to work on a circle.

Any advice would be great,
Thanks for reading my problem.
