[SUN DIAGRAM]

Sun Diagram is a SketchUp extension for 3D sun paths and sunlight analysis in architecture.

Generate a 3D Sun path by simply entering coordinates

1. Create Sunpath from Coordinates (First function)

Generate a 3D Sun path by simply entering coordinates
 There are 2 ways to create a 3D Sunpath:
From Model (recommended): Preload coordinates via File > Add Location (SketchUp 2024+) or File > Geo-location (SketchUp 2023 and earlier) for accurate results.
Manual Input: Manually enter coordinates to generate the sun path.
---------------
DST Support: In temperate countries, time zones shift seasonally to make better use of daylight. Enable this option if your location observes Daylight Saving Time.

- Sun Diagram lets you see exactly how sunlight and shadows interact with your design in real-world conditions.
- You can check any location and important time frames.
- With the sun path visually represented, you can instantly export images to send to clients.
