What is included in the SketchUp 3D Model?

Opting for the SketchUp model gives you complete freedom to explore, scale, and customize your Trillium Pyramid project before you build. SketchUp is a free program that allows you to open the full Pyramid structure in a detailed, interactive 3D environment.
This model lets you:
• View the pyramid from every angle
• Understand structural relationships and joinery
• Scale the design to your desired footprint
• Explore layout and spatial flow with clarity

Some models may also include alternate configurations or construction details not shown in the standard plans. Be sure to check the short video above in Model Specs for a closer look at what’s included in this specific Pyramid model.
