3D scene view
=============

The 3D scene view gives you a three-dimensional representation of the scene. Use it to:

* :doc:`Add shading <../shade-calculator-howto/sc-add-shading-objects>` and :doc:`active surface <../shade-calculator-howto/sc-active-surface>` objects to the scene.

* :doc:`Remove <../shade-calculator-howto/sc-delete>` objects from the scene.

* Verify the size and position of objects in the scene.

* :doc:`Resize objects <../shade-calculator-howto/sc-resize>` by selecting them and changing their properties.

* See shadows on active surfaces and the total shade loss at different sun azimuth and altitude angles.

To see shadows on active surfaces

#. Click **Location**, and verify that the latitude, longitude, and time zone are correct for your scene.

#. Click **3D Scene view**.

#. Drag (click and hold the left mouse button) the scene to rotate the scene. Your view is the sun's view of the scene (assuming parallel light rays from the sun).

The **Azimuth**, **Altitude**, and **Shade fraction** values change as you rotate the scene, and shaded portions of active surfaces will appear as dark grey polygons.
