Tool does

Explain the result

See the sampled sunlight directions around the selected targets instead of relying on a number alone.

Spot blockers

Use the ray geometry to understand where surrounding model geometry interrupts solar access.

Work as a pair

Use Preview Rays alongside Solar Exposure when a result needs visual confirmation.

From result to confidence

01
Select the elements you want to inspect
02
Generate the solar-ray preview
03
Compare the visible paths with the exposure result
