Hey Everyone!
I've created a few buildings from temple square in 3D. I built the Salt Lake Temple, The Joseph Smith Memorial building, The Church Office building, and The Tabernacle. These are the first 3D things ive created so you�ll have to forgive me if they are a bit out of scale. If anyone else wants to create buildings in 3D i would definitely recommend using SketchUp. You can download the trial version here.
Good Luck!
