How can the spiral showing be done in Hexagon?

First make the spiral using the “helix” tool under the “lines” tab.

Then make a circle of the thickness you want, centered on one end of the helix.

Now with the circle selected, use the “sweep line” tool under the “surface modeling” tab and click on the helix.

Set “taper” to zero (or some small number, you can play with the value to your liking).

That should give you what you want.

HOWEVER…  smile

If the thickness of the spiral is backwards (IOW, thick at the narrow end and narrow at the wide end), then undo it so that you have just your circle and helix lines showing.
Go back to the “lines” tab, and all the way on the right is the “reverse a curve” tool.
Select the helix, click the “reverse a curve” tool, and then click on the helix.
Now go back and sweep the circle as above. When you taper it, it will now taper in the proper direction.

Thanks for the reply I’ll get it a try.

Related question: suppose you used an ellipse to sweep, instead of a circle. Is there a way to make the ellipse rotate at the same time? So the helix would seem to be made of a twisted ribbon?

(What I really want to do is something related to a Möbius strip, but this seemed like a good general question to ask.)

Sorta - kinda - I guessa…

Without knowing exactly what will make you happy, all I can do is tell you to hack your way in by trying it. There’s 3 sweep modes and a twist function for you to play with, and even after you validate, you can still play with its dynamic geometry before you collapse it.

Thanks afreaginname it appears that your method is going to work just fine.
I’m going to have to tweak the settings to get what I want. Thanks again.
