The wheel opening could be done that way too, or you could try building the basic shape around it by arranging your “transverse” sections somewhat “radially” around it. Get the basic shape and then build the headlight opening as an extruded shape and use it to trim the basic shape. He did it just about the way I suggested. The tooling for this stamped fender was drawn by somebody with a pen on vellum using sweeps for the curves. Even the experts will need several tries to get it the way they want it. If you don’t like what you get, make some adjustments and try again. Let the surface command mathematics provide the smoothing and blending. My guess from your photos is that maybe 6 transverse sections and 3 or 4 longitudinal sections would do the job. Put the points on the section planes in the model and hand fit a section curve through them on each to your satisfaction. You will also need some points on a few selected contours on planes that you can easily place in your model as well as trace the corresponding intersection on the real part. You can get the edges and outlines pretty easily by setting up some picture frames in your model and putting your principle view photos on them. Pictures are good, but you’ll still need some reference points and dimensions. Since this kind of shape is perhaps the most difficult to achieve (at least from my perspective), I think I really need to start from advice from the best of the best for a good workflow for approaching this. (so also the surface edges inwards towards the hole for the headlights). All bent edges (inner profile) needs to be rounded/filleted ~R2 mm.Also the inner profile of the fender is curved in UVN directions (that is, no flat surfaces whatsoever).Most curvatures seems to be changing radius gradually.The headlight area is also flattened (around the hole the surface is flattened about 5-10 mm radially).The flattened inner top profile is leveled (along the length) as it’s aligned with the hood/bonnet which has a flat bottom edge.

This highest point extends as a softly rounded ridge along the entire length of the fender.

lowered & flattened towards the inner profile (the front part between the fenders also has a flat top surface seen from the front).

The shape on the highest point is rounded towards the top and outside (kind of “circling the head lights”), but it doesn’t go straight towards the inner profile, or upwards, instead it is ….

Q: What approach/workflow for shaping this kind of fender would you guys suggest? I tried searching for tutorials for this kind of shape, but since this is not exactly “free” form (as with any car body part) it needs to stay within some dimensions, and have the exact right looks at the end of the day). I don’t have any drawings for this fender, but the pictures below should at least illustrate the difficulty. Below an arbitrary example fender (but quite tricky shape, I think) for which I’d like to learn the appropriate tricks. I’ve tried creating some “modern” body shapes for cars, including fenders of course, but very curvy fenders for older cars seems to be trickier.
