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 :)

 Paul, heres a quick kick at the cat..
 Jarrett

 I am going to change the rules here just a bit.
   You must submit one of the three file extensions.
   .iges .stp or .stl I prefer .stp.
 These will be kept private. I will use them
   to render top view, side view, front view and perspective for
   purposes of judging each entry.
 You must also submit at least one rendered jpg.
 At the end of the week I will render and  publish 4 views on
   each entry. I will not judge the winner. The readers will judge
   the winner by voting after they see the renderings.
   The judging criteria is how close the submissions look like
   the stock RV10 cowl.
 This will even the playing fields as the same rendering
   program will be used for each entry. This is not a contest
   of rendering programs.
 Jeff is allowed to submit another entry due to the fact
   I already rendered and published his entry and the rules
   have changed.

 Paul

  Paul, would you like me to re-submit in a different format? I
  think I'd sent
  a parasolid but I can send it as something else?

  Jarrett

  .stp and .iges both. I'll check and see which one Rhino 3 likes
  the most.

  Paul Lamar

 Paul heres the IGES version btw were you able to open the X_T
 [parasolid] file?

 Jarrett

 I did not try the parasolid. I don't think Rhino 3 handles it but
 I will check and let you know. Thanks for the iges and step

 -----------------------------------------------------

 The iges worked but the step crashed Rhino. Nothing
 new there :)

 Bill wanted me to let him know but I declined :)


 Paul Lamar

There is actually two versions of the Step file. I tried the
latter version
but I can re-send w/ the other version if you want?

It's a bit of a large file.. lots of info in these organic shape
files..
The IGES solid file [the one I sent was a simplifed surface only
file] was
39Mb.

Jarrett

I am surprised it got by earthlink :)
The iges you sent will be sufficient.
My earthlink mail box is only 200meg.

PaUL

Sorry, the IGES file I sent was only ~3Mb [it was the "surface only"
version] the Solid version [had a enclosed volume which was 0.06"
thick < the "body" of the cowl] was 39Mb but I didn't try to send it
as it breaks the 10Mb rule..  I've yet to see anyone be able to
accept an email into their inbox w/ more than 10Mb.
