Grain Auger... Help

[not registered yet]

Hi, Ive been working with Sketchyphysics for about 3 days now and have not been able to figure this one out. Im trying to make a "grain auger" type thing. Just take a look at the skp and you will see what i am talking about. Anyways, the problem is that I cant seem to find a shape that sketchyphysics knows what to do with.

Ive tried doing this several different ways but nothing seems to be working.

I am looking for ideas on how I can make this work.

Its purpose will be to get some balls from the bottom of a course to the top of it (roller coaster type idea)

Thanks for any input you can give, great fun here

ps.im building my version of your bridge

You need to make the "blade" out of a bunch of boxes. Here is an example by Google Guy from 3dwarehouse:

ahh, now i see how its done. what i wasnt doing was creating a bunch of convexhull shapes and then grouping them together.
