Here is the challenge.
Start with this data and do a 3D cowl
for an RV10 that looks like this  one using what
ever 3D program you have.

It must be rendered.
Assume a 12 inch spinner.
It must be to scale.

This is all the info you have to go on.
Assume max width is 41 inches.

I will be the judge and I will abstain
from doing one now.

You must submit a iges or stp file.

All the guys touting their favorite 3D program on here
so far must participate or they will be vilified and ridiculed :)
In other words put up or shut up :)
