Michael,

Been playing with the flow command..twist very cool btw...and have been ending up with the surface tearing apart on the end which you can see in the screenshots. Only way it doesn't tear if I set it to rigid which kinda defeats flow on curve. Wondering if this is a bug or am I doing something wrong. I attached the file for you to look at. I had the twisted rope all closed at first - meaning ends capped and bottom closed..same thing - tears..I deleted the caps and bottom and same result.

Thanks for your help

Hi jpaluck, you're not doing anything wrong, this definitely looks like a bug, I'll check into it.

It looks like some kind of bad side effect from what was supposed to be a bug fix for flow.

Michael, This may be a bug too:

When I go to run flow on the wheel object, using the circle with the straight line as the base and the circle with the spiral line as the target -
All objects on the screen disappears when you run the Flow command.

Look at the two files: spiral_twist_ex02_1stBeta.3dm and spiral_twist_ex02_2stBeta.3dm files were made in the respective app versions.

You have to try to flow the wheel object in the new Beta to test it.




In the last beta, the flow works fine.

Note: that the above picture is from the first beta, where Flow worked. (it did NOT work in the new beta, everything vanished) The spike on the flowed object is just a product of the objects being flowed in the degenerate area, but not the bug I'm talking about.

Hi Mike - thanks, that's probably the same bug - it seems to be generating some massively mangled object that is astronomically large - if you push "Done" and then look at the properties panel you'll see it has a size of 54x54x66390776 units, that huge object size is what messes up the display.

I'll take a look at this one too. Maybe if I can figure it out today I'll put up a new beta.

That's great -

This morning I had another strange result with flow but didn't get a chance to save it.
I Twisted a box, then Flowed it along a curve. Very simple, right.
The result had some kind of exploded nastiness in the middle. Since I was flowing on a curve to curve basis, it didn't make sense.

Good luck!

Hi jpaluck & Mike - these problems with Flow that popped up in the 2nd beta that you reported in this thread here should be fixed now in the new one, please let me know if you still see Flow misbehaving like that again. I think I've got it tuned up pretty well now though.

- Michael

Riko, the above image is an object that was twisted using a "flow on revolved surface" technique.
See here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=4549.1
The twisting in the wheel object above was done by using a flat revolved circle for the reference plane and a surface that was twisted as the target.
So the Flow command will match the two surfaces and you will get an object that matches the point structure of the target surface.
The twisting of the target surface was really a cone that was twisted and then flattened.
I hope this explanation helps, I'm not sure how to else describe it.

The turbine shape in the second image looks like a Twist command was used.

Hi Riko - yeah like Mike mentions the first one is a little different using that technique with Flow that Mike cooked up.

The second one is kind of easier - that's using the new Twist command in the latest beta, you can get the latest beta here: http://moi3d.com/beta.htm and there's a new Twist command in there that you can find under Transform > Deform > Twist. You draw an axis for the twist and then enter in an angle for how much rotation you want at the top of the axis and it will twist your object around that axis line.

I'm still working (kind of bit slowly interspersed with some other work) on gathering some more descriptions of Twist.

Thanks for sharing that example Magic, really shows off the myriad possibilities of this new feature.
