Radar tool: change spacing between spokes?

[Roger Breton]

Simple question: is there some option like some extra keyboard shortcuts to change the spacing between spokes? Here's an example:

As you can see, to replicate the form behind in gray, I only need 4 spokes (circles).
BUT I need to reduce the space between the circles? Interactively?
Otherwise, I'm going to have to use the Blend tool

You need the inner one larger? That cannot be achieved with the radial grid tool.

[Kurt Gold · Accepted solution]

With the Polar Grid tool you can interactively change the skew of the concentric dividers by pressing a key while drawing with the tool. It depends on what keyboard layout you are using. On a German keyboard it is the X and C key.

However, it probably does not help in your case.
