Altitude reference

Available in any Viewpoint Inspector, click on the xyz... coordinates button.

Altitude reference: Allows you to define a distance in reference to a clicked geometry. By default, the value is 0. Z position means the camera is set at a height starting from the absolute origin.

To set the camera height at a relative value from the absolute origin:

Click on Target tool .

In the preview, click on a geometry - e.g. the room floor. The Altitude reference Z dialog now refers to the 0 and the height of the room in global coordinates. A yellow line is drawn between the two Z values.

The Position of the camera Z refers only to the distance between the room floor and the height of the camera.

Type a new value in the Z Position field. This changes the camera height in the Preview relative to the altitude reference.

Type 0 to disconnect the yellow link and return the Z value in reference with the 0 height.
