You can open or close your shading element using the arrows in the left-hand side of the object panel. The right-hand side of the panel shows the current position and the angle of the blinds.

You can also operate each blind element via the operator panel by using the sliders on the right and on the left, or dragging the point in the middle of this window to the desired position. If you have defined a favourite position and wish to use it, simply click on the button “go to favourite position”.
