- Analyse direct sun on selected surfaces or supported Windows and Doors.
- Display an exposure heatmap or compare results with a chosen sunlit-area threshold.
- Use a sensor grid to examine sky access over selected floor slabs.
Solar study settingsDefine the location, times and model elements to analyse.
Check the project location, north direction, time zone and daylight-saving settings before running a study. Set the date, start and end times, and sampling interval. The interval determines the times at which the sun is sampled.
Select the intended surfaces, or collect supported Windows and Doors from the 3D view. The visible model affects what can be analysed, so set the model visibility for the intended study before calculating.
Exposure and Pass / Fail resultsChoose the display that answers the study question.
Exposure Heatmap shows how direct-sun exposure is distributed over the analysed area. Pass / Fail compares the result with the selected sunlit-area threshold.
These are different ways of displaying the study results. Rerun the calculation after changing the model or analysis settings. The results assist design review; they do not provide certification.
Daylight studyPlace sensors over the selected floor slabs.
Select the floor slabs, set the grid spacing and preview the sensors before calculating. The sensors are positioned above the slabs, allowing the study to compare access to the sky across the floor area.
The calculation uses a simplified model with a uniform sky and ideal windows, without reflected light. It reports sky access rather than illuminance in lux. These assumptions matter when interpreting areas close to walls, openings or obstructions.
Sun-Eye is covered in its own guide. Cropped shadows and Shadow diagrams remain in development and are not part of the initial release.
