F1 car design in Catia V5 x

I left off having created some new guides for the airbox

These guides need to be combined and added to the geometric set 3D GUIDELINES.

I think we've got all the guides needed at this point. One question remains. What is the shape of the airbox profile? I've got nice top and side 2d images, but nothing from the front or the back. The nose practically builds itself, because it's not that complicated of a shape.

I got the idea of this method using after looking at this:

Freestyle workbench, top view. Insert a new geometric set "AIRBOX FRONT VIEW" under the 2D SKETCHES set.

Start tracing the 2d top sketch at the airbox one line at at time. When I say one line at a time, I mean that every time there is a curve, it should be a constant radius curve. If the curve changes, create a new line.

Have a look from the front. We know this is a roll hoop and it should be curved.

Impose tangency and curvature.



Once a line is drawn, change to the 2d side sketch and adjust that line that was just created, so that it works on the zx axis as well.

Ok, add another 3d curve, starting from the endpoint of the previous line. Impose tangency and curvature.

We're going to start switching views back and forth from the top and the side, refining and adding 3d curves one at a time.

Close is good enough at this point. When you have a 3d curve that looks like this, make sure to only move it along the z axis in the side view and only along the x axis in the top view.

Keep adding lines until you get to the bottom

Now take a look from the front

That'll do as a guide
