Perfectly circlular walls/roads in CD3? Establishing scale in CD3?

[NeonKnight]

Oh, ok, for the first, there are a few simple tools.

To draw consecutive circles do this:

1. Select DRAW CIRCLE tool, and draw your first circle.
2. Then LEFT CLICK to start a new cirlce.
3. RIGHT CLICK again and your new circle will automatically be centered on the first circle.

Already drew a circle and want to centre a new circle later on that one. Select DRAW CIRCLE, before clicking anywhere on the map, use the CENTER command (looks like a blue circle with a red circle center), and then select the circle you want the new circle centered on.

As to determining scale, at the top, select the INFO drop down menu, and the bottom five selection are: Coordinate, Bearing, Distance, Length Along and Area.

Ok thanks, I think I get it mostly. The one last thing I would like to ask though is about changing the fill. What is the best way to change an objects fill?
