For those searching how to also flip a part that is rounded, especially in older versions of gibbs, you can use Modify> mirror and use z to mirror. I found this after forever being frustrated in Gibbs 2011. I'd love to hear of another way in Gibbs that is that old if anyone knows. Imagine you have a donut cut in half like a letter C ....That shape, if you import and you want the rad to be up like an upside down U. Always had a difficult time aligning with shapes like that. Thanks for the vid!!
