Bugatti fender buck in Rhino 2.0 using Alex' version 12 iges file.

There may be an easier way but I haven't learned it yet.

I bring up the fender and an intersecting plane where Wray wants the main spine of the buck, and issue and Intersect command. That gives me a line where the fender and the plane intersect.

I put the plane just a hair onto the edge of the outer half of the fender out of habit, caution, I want to make sure the plane intersects the fender.

Adding a horizontal member where Wray had one indicated

Checking the position at the rear of the fender.

It needs to go through the furthest back portion of the section

(Also we can see that more information is needed to define that back edge on the wing section.

I make a rough line to show where the inside edge of the fender is. I want to turn off the fender data and get it out of the way so I can see what I am doing.

I go up to layers and turn off the fender data.

I tell the program to divide the intersection line I made back the the first picture up into 24 parts. and then chose a tool that draws lines perpendicular to a curve. I draw a line at each of the 24 points and pull each of them into the fender well until they reach past the line I drew of the inner edge.

Once these lines are drawn, I extrude them out to make intersection planes for the buck stations.

Once the intersection planes are established I turn the fender data back on , select everything and then tell it to show me the intersections again.

This generates all the edge information for the cuts on the buck.

Here are the lines that show where the edges of the sheet metal buck would be if I built one. I put the tire back in for position and scale.
