Masking Tool

(available from version 2.3.3)

Located next to the preview window, the Masking Tool allows you to draw custom shapes to hide or reveal specific areas in your sun and shadow analysis. This helps create cleaner visuals and lets you focus on the areas that matter most.

The mask is especially useful when isolating areas for focused study, such as:

  • Highlighting specific facades in a sun-hours analysis
  • Studying shadow-sensitive areas like parks, plazas, or outdoor amenities
  • Evaluating zones affected by shading from nearby structures
  • Analyzing landscaping areas designated for planting
