Dotted or dashed lines?

Is there any way to draw dotted or dashed lines in SketchUp ?

Try my 2dLineStyle SketchUp Plugins | PluginStore | SketchUcation

draw a line (or an arc).
right click on it.
choose ‘divide’
type in an odd number, eg 5
your line is now split into 5 segments
erase the 2nd and 4th segment of the line.

Hurrah
