Rear window and rear Louvre's

Let's have a look a reference image that clearly shows the Louvre's covering the rear window.

Reference image

We start with modeling the Louvre's and then add the rear window.

As usual we use one of the car parts we already modeled and duplicate that. This time we duplicate the Roof object and rename that to 'Louvre-Frame'. Select the edges as shown in the next screenshot:

Select these edges

Extrude them downwards and then select the newly created faces:

Select these faces

Then select Edit -> Invert Selection from the menu bar (or press Ctrl + i), to deselect all selected faces and vice versa. Then delete all selected faces.

    
Invert selection..                     delete the selected faces and you get this..

Now switch to top view and create a new SDS rectangle. Rename this rectangle to 'Louvre'

Rectangle added

In Edit Points mode, the vertices in the corners are moved to match the blueprint. And because the Louvre is slightly bent, add two vertical edges (and thus also two vertices) with the Knife tool and then again align the shape to the blueprint.

Edges added with the Knife tool

Now apply the Extrude tool two times to add some depth to the Louvre's object. Use the following tool settings:

Remember you can use the Again function from the pop-up menu in the view window, to repeat the tool with identical settings.

After the second extrusion, select the middle edge (as shown in the next image) and slightly move it just a little bit outwards. This creates a nice smooth rounding which is important for the correct light reflections later on.

Select this edge and move it slightly outwards

Then select all outer edges (upper and lower horizontal and vertical edges) and set the Edge Sharpness to ' Sharp'

Select these edges and make them sharp

Next, switch to Edit Points mode and make sure that the inner points of the Louvre are exactly at the mirroring axis of the car. Also make sure that at the vertical edge between the two arrows there are no more vertical faces. If there are, you can remove them:

These points must be at the mirroring axis

To create the remaining Louvre's we only need to create instances of the original Louvre. Press the space bar and make sure you are no longer in edit mode. Take a top view, select the Louvre object, press and hold the Alt key and drag the green transformation handle in the View window to create a new instance. You need to add three instances in total. The biggest advantage of using instances is that they require less memory. When done, move all objects to the Lamborghini level in the hierarchy in the Select window.

All Louvre's created (mirrored objects also visible)

Then move each of the Louvre's into position so they are all aligned with the roof structure:

All Louvre's in position

Now it's time to model the rear window. We use another SDS rectangle for that. In top view, create a SDS rectangle:

SDS Rectangle added

Rename the rectangle to 'Rear Window' . Then switch to side view and adjust the position of the Rear Window. It must be rotated slightly and then moved just under the Louvre's:

Rear Window moved and rotated into position

And we're done! Save your work before continuing with the next chapter!
