The Follow Me Twist
-
Most of you know what happens when using the FollowMe Tool around a helix - the profile twists as in the following image:
It seems to me that the resulting twisted geometry is seldom the expected or desired result.
I was just curious if anyone relies on this twisting behavior, or uses it to advantage? Or should the default be to not twist?
-
I don't think I've ever had any benefit from the twist. How does one predict it?
-
I have only heard complaints about it but cannot remember a case where it would've been useful to anyone. It doesn't mean that it cannot be useful of course but it has always been mentioned as a "limitation", not an advantageous feature.

Does anyone know how to get rid of this undesired result and effectively extrude around a helix?

I'd like to keep this topic about the behavior of the Follow Me tool, and not about how to make a screw. For that, please refer to this topic. Thanks.

There is always the Follow Me and Keep ruby script, but it has the disadvantage of distorting the cross section shape and creating double the amount of faces compared to the built-in command, so for round tubes I always use that, despite the twisting.

i think it might be predictable but i haven't ever tried to figure it out (and frankly, i don't care too
)SU follow-me keeps all the faces coplanar as if you were extruding the shape around a circle. that's the limitation that causes the twist.
1001bit will break the faces thus allowing for a non-twisting helix followme.

My guess is it has something to do with what SU calls an "arbitrary axis rule" (pulled slightly out of context from the API).
Followme works nicely on a sphere. Try drawing a helical path over a sphere, then follow me along it. The face will align itself nicely onto the sphere.
