9. Annex 2: Inverting normals

We created a cube of side 2. We select the cube and click on normal button in the upper bar.

The normal vectors with their senses are visualized.

By clicking on the main window the sense of the normal vectors are changed.

By clicking on the "Normals" button the new normal senses are saved.

By clicking on the "shaded with lines" button the cube appears with a dark color because its normal is pointing ingoing.

We click again in"Normal button" and then in the main window the change the sense of normal. Finally we click on "Normals button" to save the new normal sense.

Now we have the cube with a brilliant color because its normal is pointing outgoing.

Some time is useful change the color to a more clear one. For that click on Layer, manage layer.

Change the color of the layer

Now we will change the sense of the normal of only the surface in the top of the cube. We select the cube and explode it

We select the surface in the top and click on the "Normals" button.

We click on the main window the change the sense of the normal of the top surface

We save the new normal sense of the top surface by clicking on the “Normal” button.

Now the top surfaces are darker than the other surfaces because the normal in the top surface is pointing ingoing.
