Shadow Slice is a SketchUp extension (plugin) designed to create transparent 3D sections for interior shadow analysis. Smart material blocks sun, stays visible

Why does the Sun Diagram plugin only show a limited number of months/dates (e.g., June, September–March, and December) instead of all 12 months?

To accurately represent the full range of shadow conditions throughout the entire year, only three key dates are truly necessary:

☀️June 21 – Summer Solstice (Northern Hemisphere) / Winter Solstice (Southern Hemisphere)
→ Sun at its highest (or lowest) position → shortest (or longest) shadows of the year.

☀️December 21 – Winter Solstice (Northern Hemisphere) / Summer Solstice (Southern Hemisphere)
→ Sun at its lowest (or highest) position → longest (or shortest) shadows of the year.

☀️March 21 & September 21 – Spring and Autumn Equinoxes (same for both hemispheres)
→ Sun rises exactly east and sets exactly west → medium-length shadows that represent the “in-between” conditions.

The Workflow:
SketchUp ➝ Export Image ➝ Nano Banana ➝ Final Art
