How to create hatch/fill for curved wall in Layout

I am understanding basics of Layouts new Pattern fill tool.
I cannot figure out how to fill a curved shape. (A curved wall in this case.)

You can’t apply the Pattern tool to faces that exist in your SketchUp viewport. The pattern property only affects shapes created in LayOut. For more info, check out my tutorial

You don’t need this tool, just use Skalp for Sketchup ( and all your sections are filled automatically in Sketchup and Layout.
