Founded in 1999 and based in Boulder, Colorado, @Last Software the maker of SketchUp was created by a small group of AEC software industry veterans. This group envisioned developing 3D design software that would make design exploration accessible to everyone. The mission: 3D for everyone. It’s more than just a tagline though. It’s a vision that guides us to provide the best possible tool for bringing you designs to life in 3D.
