The free plugin gives modelers the ability to easily create a multi-faceted face inside of a closed group of three or more lines. Josef Leibinger's Soap Skin & Bubble plugin for Sketchup is one of the most exciting things to happen to Sketchup in quite some time. One of its biggest drawbacks is that it has a hard time modeling organic shapes with NURB attributes but luckily it doesn't have to stay that way any longer thanks to the Soap Skin & Bubble plugin.
Sketchup is a great tool for modeling all sorts of shapes and objects.
