Smoothing a freeform object?

I have drawn a closed 2D freeform object using straight lines, arcs and partial circles. It doesn’t look as smooth as I want. Will the smooth command make it flow better? How would I access and use this command? any help would be greatly appreciated. I could not find any help at sketchup knowledge center.

Share your SketchUp model file so we can see what you’ve got and tell you how to fix it. Also complete your profile with SketchUp version/license. That information will help us know what sort of capabilities you have.
