# 3D Design Tool Overview The Powerlily 3D Design Tool is a comprehensive application that allows you to create and manipulate 3D structures for solar design and analysis. With intuitive controls and powerful features, you can design accurate solar installations quickly and efficiently. ## Key Features - **Hybrid 2D/3D Design Interface** - Seamlessly switch between 2D and 3D views for optimal design workflow - **Intelligent Drawing Tools** - Create building structures with multiple shape assistance modes - **Solar Panel Placement** - Precisely place and configure solar panels with automatic spacing - **Obstruction Management** - Add roof obstructions like vents, chimneys, and HVAC units - **Tree Placement** - Model shading from nearby trees for accurate shadow analysis - **Shadow Analysis** - Visualize shadow patterns throughout the day and year - **Production Estimates** - Get real-time solar production calculations via PV Watts - **Annotation Tools** - Mark important features and add notes to your designs - **Export Capabilities** - Generate reports, BOM, and export CAD files (DXF) ## Getting Started To begin designing: 1. Select your imagery source (satellite view of the property) 2. Enter drawing mode to create building structures 3. Add any obstructions to the roof surfaces 4. Place solar panels on the structures 5. Add trees if needed for shadow analysis 6. Review production estimates and make adjustments 7. Generate reports and export your design ## Navigation - [[General Controls]] - Camera navigation, selection, and interaction - [[Drawing Mode]] - Creating and editing building structures - [[Panel Placement]] - Adding and configuring solar panels - [[Obstructions]] - Managing roof obstructions - [[Trees]] - Placing trees for shadow analysis - [[Annotations]] - Adding notes and markers - [[Extras]] - Special objects like lawn signs and vehicles - [[Shortcuts Reference]] - Complete keyboard shortcuts guide - [[Terminology]] - Key terms and concepts ## Next Steps If you're new to the design tool, start with [[General Controls]] to learn the basics of navigation and interaction. Then move on to [[Drawing Mode]] to create your first building structure.
