Curved lines (for garden beds-landscape design)

Good morning. I am a novice Sketchup user. I am trying to make sweeping garden beds (also called curvelinear) I am having trouble making curved lines EASILY. I am hoping someone can inform me the easier way to make multiple curves in a row.

Can someone tell me what tools to use to make curved lines as shown in the picture below?

I would probably use one or another of the tools in Fredo6’s FredoSpline. You can create nice curves and then tweak them as needed until you are happy with them. FredoSpline is available from Sketchucation.


The 2 point arc tool is designed to carry on making curves that flow from the previous one. So you can do some very nice stuff with it.
