Howto: Bend (and twist) a long rectangular box for 400 degrees

ZBrush Usage Questions
#1

I’ve been struggling with this for a while now and I can’t find a way to make some sort of helix that spans about 400 degrees. I would get the effect by making a long, rectangular box and arc-bending it for 400 degrees. But in that case the ends would overlap, which in a helix is not the case.

I’ve tried using the helix primitive with four sides, but I can’t get the sides turned 45 degrees.

I’m on zbrush 2018

Here’s an example that’s almost what I’m after, but as you can see it is still twisted, it isn’t like a large rectangular box that has been arc-bended.

If starting with a helix I run into the following issue: Is there a way to enter the ‘twist’ values by hand instead of dragging the points in the small window? That’s just not precise enough.

Initialise (settings for stuff like this with input boxes for all the basics) To set up parameters…

Thx, but the thing is that there are no input boxes for ‘twist’, only a window where you have to drag/draw a curve to set the values. And that simply isn’t precise enough.

#5
Try using the Spiral3D primative instead of the Helix3D primative.

The Coverage slider and Twist slider is in degrees. Click on the slider to get a red box where you can enter numerical values.

Thanks! That’s almost what I’m after, but this is still a square that is extruded and bent, not a rectangular shape.
