Since skylights are a sub-component of ceilings (which we don't visualize, more on that here) and due to other technical challenges, we can't automatically measure their geometry.
Instead, we provide an easy option for adding skylights manually to any room after you have completed a scan and are viewing the 3D model.
How to add a skylight in 10 seconds or less
Scan a room and view the 3D model
Select "Skylights" list item in the sidebar
3. Select the "+" button to add a skylight
4. Modify the dimensions and direction and other assumptions as needed
That's it!
