None taken, but here's a few stupid questions: How do I modify the template if it doesn't fit what I want to do with it? -and- Why isn't it a sphere with a cone for a tail?

I'm planning on a micro car project, half as wide and tall as a "normal" car but nearly as long. Let's say 2.5 feet wide and 4 feet tall by 10-12 feet long. I scale the template. Do I add flat sections to stretch it, or stretch the front only, or stretch the whole thing? I don't want to increase frontal area just to get a better cd and worse cdA.

Sorry for the off topic.
There are no stupid questions,only the one that was never asked.
With respect to modifying the 'Template',if you must do something,go 'hyper-'Template' and make things longer with a little extra surface friction.
If you go hypo-'Template' you'll get flow separation and really high drag.
