heh.. i didn't cheat either.. by cheating, i meant that i showed it in sketchup when it was modeled in a different application.
Ah. I see. I drew mine entirely in SketchUp.

You guys make me want to run and hide Here I was proud and happy that I finally got the screw created and then you guys just blew me away.
@box that is a really neat animation. Curios about the software you used for the animation.
@Jeff - that was a really interesting video.
@DaveR - I like the way you had multiple pitches to your helix and the transparency to the finished blade.
Honestly, I enjoy feedback like in this thread. For people like myself you certainly help me to advance my skills by reaching out and, at the very minimum, trying to learn new things which I do not normally use in the work I do. One never knows when one of he "tricks" you learn from these exercises will help solve something you are trying to do.

There is an auto intersection at one place!

I suppose yes
Else Albertsoft is like your Rhino!

haha.. i like your line choice for pointing out the problem in that picture

It's all Sketchup, just a very simple bit of Sketchy Physics.
Here's a quick one for those with an everlasting sweet tooth.
You'll have to take my word for it that there is a lifting mechanism inside bringing the balls back to the top.

It's done with a plugin called Sketchy Physics, one of the most frustrating and fun plugins ever sent to torture us.
There is a servo hinge on the little door at the top that opens with a slider and then it is simple gravity that makes the ball run.
The chains, pulleys, buckets and assorted clockwork machinery that is running on the inside to elevate the balls, is a tad more complex.
I'll warn you now before you rush off to try it, it doesn't work with 2015 yet. -

Another "learning" question: How do you achieve the indented curve look of your spiral blade? I have never had to do anything like this but when I learn tricks like that from you guys it helps me get a better overall grip of the tool.

Actualized and debuged by Anton
And a new other engine physic must be released always by Anton!

Oh I got all of that. It was not the array that was the problem, it was that when I copied the array and moved it up on the blue axis it did not line up? Guess I'll try it again...
Reason you have the unconnected points the line you are dealing with is really a diagonal of a rectangle and needs to be longer than the segment of the circle and the angle is established by how much you want the lead angle.
To get the correct angle and line length just extrude the top face of the circle for example 1 foot, draw a diagonal line from one circle end point to the next one on top the that circle, that will give the line length and the angle. The you can do the radial copy and they will match, then do a right to left select of those lines and use the array copy to copy to height you want or you could delete the lines you don't want and then copy up=> up to you.
BTW the 1 foot is probably bigger than you want since you are moving up 1 ft for each 15 degs. of rotation assuming you are using the default 24 seg. circle. That is your design decision. Moving up the end point will also work but you need to be very careful to use the inference engine or you can easily be in error by a small number -

Not exactly, Sketchy creates the animation within sketchup and I have simply used a screen recorder to capture it. I think the plugin has a way of exporting the animation, but I've not gone into that and I may be wrong. I know it does save animations that you can view from any angle though. Having looked further I see you can export the animation as PNG, JPG or SKP frames.

There are quite a few ways, everyone has their favourite, screw was mentioned a few posts back, curviloft will do it, some of tig's tools etc etc
This is one way, Eneroth makes some fantastic plugins but is very quiet about them, better known on the Extension warehouse I think.
This is done using her Upright Extruder.
