Anytime!

Thanks.

I create another file, copy and paste the outline, and section the removable parts, detailing each individually, while making sure they're all sturdy enough for use.

Phase five - Breakgroups and applying body panels

I apply each body panel by copy and pasting each upon the body, but making sure each panel is connected through a series of breakgroups and not directly to the cabin.

Phase six - tuning

The longest phase of them all, I make sure the car runs well and crashes well, reducing wobble and removing excess.

This is the way I do it. It's lengthy, but this method is actually a lot more efficient than doing it all on one file.

@StormPilot It was done in phases.
Phase one - Outline

First, I measure out dimensions and the wheelbase, as well as the wheels. This car's dimensions were based off of a AMC Javelin. I create an outline of the body, forming the shape using small golden ratio references to form decent looking proportions, while maintaining the theme of the car.

Phase two - Preview

I panel the outline and adjust little details towards my initial vision.
Phase three - Body

I copy the frames of the preview onto another file and develop a working frame and cabin. I make
sure it moves before anything else. The suspension must work, and the frame must be sturdy, also I add some little details on the interior and such.

Phase four - building the body panels

just wondering, how exactly was this done?
