    What is included in the Sketchup 3D Model?

            Opting for the Sketchup model allows you the ultimate freedom when exploring, scaling or altering your Trillium Domes project. Sketchup is a free program that will allow you to import every detail of your Trillium Domes design into a workable, digital space. This gives you maximum creative potential and a totally different view of your project. Many files include alternate designs never released as plans! Check the short video above in Model Specs to see a detailed view of what’s included in each specific model.
