Display but on't render
My first post. I tried IRC, but couldn't find anyone, or I was in the wrong
place.
Anyway, I've been working on my first polyhedron for a bit now. I got it
just like I wanted it, and everything displays fine. However, when I tried
to render, the polyhedrons just disappear. There is no message in the
console. All my triangles appear correct when I View->show edges. I was
hoping that someone might tell me how to go about troubleshooting this. I'm
not sure where to look for debug information.
Here is my complete code, but the fins are what is causing the problem.
Thanks.

It's #openscad @ freenode (http://webchat.freenode.net/?channels=#openscad)

Some faces are flipped, you can see that in the "Thrown Together" view
(those show up in pinkish color).
See https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Primitive_Solids#polyhedron
Here is my complete code, but the fins are what is causing the problem.
Try with:
faces=[[0,2,1],[0,3,2],[0,4,3],[5,6,7],[5,7,8],[5,8,9],[0,1,5],[1,6,5],[1,2,6],[6,2,7],[2,8,7],[2,3,8],[3,9,8],[3,4,9],[5,4,0],[5,9,4]]
ciao,
Torsten.
Maybe "Thrown Together" view could be renamed to something more
descriptive. Maybe:
polyhedron-check-view
Or is there another use for the "Thrown Together" view that I`m not aware
of?

I think it would be more useful if it was transparent (a=0.5 say).
ATM it doesn't show internal inverted faces.
