I'm working on the rear fenders of a Ferrari 458 Italia. This is the first car that I am modeling without a tutorial. I have one problem:

I can't finish the left part of the rear fenders (look at the images below). On the blueprint, I can't find it clearly. I think it's too rounded on the left side. Does anyone know how to model panels like these the right way?

This is the blueprint that I'm using.

    $\begingroup$ Welcome to Blender.SE! In order to make your question a little clearer to us (and more helpful to others with a similar question) it would be helpful if you can phrase the title in terms of the operation you are trying to do (e.g. "how to model geometry in ... shape") instead of the goal of your project ("how to model a bumper on this car"). As it stands it is not immediately obvious to me exactly what you are after here. $\endgroup$ – PGmath Feb 10 at 20:50

Reference Images

Always use lots of photo references in conjunction with your blueprints when modeling an existing car. Photos can reveal much more about the car's surface than blue prints alone.


Shrinkwrap Technique

Basemesh

For trickier surfaces, it is good practice to create a "base-mesh" that is as smooth as possible before creating the final mesh. Then a final mesh can be modelled over it and shrink-wrapped to it to create a more perfect result.

A good way to create the base-mesh is to model a larger portion of the car ignoring all panel gaps and finer details. To ensure that the reflections are as smooth as possible, carefully plan the topology and keep the vertices relatively sparse. When it is finished, you will usually need to bump up the number of subdivisions to a high number, usually 3 or 4.

Pay special attention to how the reflections flow across the surface. It's important!

You would model more than just one panel for the base-mesh, typically the whole side, rear, or another large area. I only modelled a quarter panel to save time.

Final Mesh

Once the base-mesh is satisfactory, you can model final panel meshes over the top of it using the Shrinkwrap modifier to keep the pinching in check. You can now include all of the panel gaps and cutouts without constantly worrying about nasty surface quality!

To make the panel gaps nicer, you could use the Solidify modifier set to "Only Rim" to create a lip around the edge followed by a Bevel modifier set to bevel by angle.

Obviously, this isn't the quarter panel that you're modelling, but the same principles apply.


Keep Practicing!

There is no single answer. There are a million ways to model, so start modelling and watching tutorials! Develop your technique!

I can't magically place real experience and hours of modelling into someone's head!
