F1 car design in Catia V5 xxv

Last time I didn't quite finish the airbox. So let's continue.

Next up is this transition from the airbox to the head rest


I'm going to essentially offset the bottom of the Front Airbox Opening


Here I've got a curve that matches the tangency and curvature of the offset


Now, I want to start putting together the face of the airbox opening. I'm going to create a flat sweep at the forward most point of the airbox.


Project the underside and airbox opening


Split


Split again using the car body


We're left with this


Now for the cockpit back, it looks like it's a slightly concave in the middle, whereas it looks straight at the bottom.

I'll use three lines as guides, one slightly set back in the center, bulging slightly outword on the sides


Project the outside lines onto the surfaces of the whole car


Chop the top off these guides


Create profiles in anticipation of a multi-sections surface


Create a couple of multi-section surfaces


If you trim the two, the result will be ambiguous, but it will allow you to fillet the edge. So select the surfaces to keep.


Fillet the edge.


Now we need to connect the two


I'll just copy and translate the airbox underside to be lower


Project it onto the surfaces


Split using the projection


Blend


Alright, now I'm going to split a bit of the headrest, airbox face, and airbox from the whole car. The goal of this is to blend them together

Here we are, after organizing a little bit


Extract edges and project


Join, smooth, offset


Project


Split


Now create a 3d curve to split the sides with. First offset the COCKPIT OPENING OUTSIDE EDGE curve on the zx plane


Then I'll just make a straight verticle line


Put a point on the offset curve and split it


Connect with a 3d curve imposing tangency and curvature. Join and smooth all.


Project onto the surfaces


Split



Split the projections


Blend


Quick mock up
